The Martian

This year marks the 50th anniversary of the first moon landing. The world no doubt thought following NASA’s incredible achievement in 1969 that lunar exploration would become routine. As it turned out man last visited the moon just 3 years later, leaving a vast 47 year wait (and still counting) for a return.

Space it seems, is now pretty boring (we suppose it is mostly empty anyway), only utilised in 2019 to enable aubergine emojis to be sent around the world and to allow drivers to completely ignore road signs.

Hollywood however hasn’t forgotten the romanticism of a proper space adventure, and in 2015 ‘The Martian‘ showed us via incredible attention to detail how a manned mission to Mars might look. It even had it’s own star car, the funky and yet very probable-looking Mars Rover.

This is that vehicle, albeit in Technic form, as built by Samolot of Eurobricks. Underneath the movie-realistic exterior Samolot had included an array of clever remote control functionality, all of it powered by LEGO’s own Power Functions motors and controlled via the third-party SBrick bluetooth brick and mobile app.

Each of the rover’s four enormous wheels is powered independently by a separate L Motor which – due to their size – are ingeniously housed inside the wheels themselves. All four wheels steer too, courtesy of a Medium Motor, whilst independent suspension allows the model to traverse the rocky martian landscape.

Finally two more Medium motors power the rover’s winch and rear crane (switchable via a gearbox) and an on-board compressor that feeds air to the crane’s pneumatic cylinders and those that open the cockpit doors.

Samolot’s creation is superbly accurate to the ‘real’ vehicle that starred in the movie and there’s loads more to see at the Eurobricks discussion forum via the link above, including a video of the model in action. Click the link above to make the trip, and remember that help is only 140 million miles away…

M-Strider

M-Tron have gone badass! This marvellous contraption was found on Brickshelf by one of our Elves today, and it continues M-Tron’s transformation from nerdy magnet collectors to fearsome space heroes. Or something like that. This M-Tron ‘M-20 Neon Strider’ by CP5670 not only looks bloody brilliant, but feed it compressed air and eight pneumatic cylinders and fourteen switches will cause it automatically (and probably very spookily) march its way across the floor. Now there’s a way to terrify your cat. Head to the Brickshelf gallery via the link above to check it out!

Tow Two

Every so often a creation arrives here at The Lego Car Blog Towers that makes us all go ‘…woah!’. This is one of those times. This beautifully presented model is Lucio Switch’s ‘Tow Truck MkII’ and it’s ridiculously brilliant.

As you’d expect for a model of this size (c10K parts and weighing 12.5 kgs) Lucio’s tow truck is motorised and remotely controlled, but before we even start looking at the electric functions there’s a host of non-motorised features to detail. These include all-wheel suspension (independent up front and live-axle at the rear), a fully suspended and pneumatically tilting cab complete with opening and locking doors, pneumatically suspended seats, and a V8 piston engine underneath. Storage lockers open on each side of the truck and five sets of Power Functions LEDs light the head and tail lights.

Which leads us nicely to the motorised functions, all of which are driven by LEGO’s Power Functions system with three on-board batteries hooked up to four third-party SBricks, allowing programable bluetooth control.

Nineteen separate Power Functions motors are present in Lucio’s model, with four XL motors powering the 8×4 drivetrain and three Servos turning the front two steering axles. Next are eight Medium motors, the first of which drives the pneumatic compressor that operates the aforementioned tilting cab and suspended seats.

The remaining seven Medium motors power the rotation and extension of the two enormous front outriggers, the extension of the two rear outriggers, the towing arm, and the rotation of the crane boom, whilst four Large motors power the crane lift, boom extension, and the two independent winches.

The four SBricks allow all of that functionality to be programmed neatly onto a smartphone from which the truck can be controlled remotely via bluetooth (take a look at the video below to see this in action), as otherwise you’d need a very large joystick controller indeed!

It’s one of the most outstandingly impressive Technic creations of 2019 and furthermore Lucio has presented his model beautifully, with superb high quality images and an excellent video demonstrating the truck’s functions. You can watch that video below, and you can see all the images at Lucio’s ‘Tow Truck MkII’ Flickr album here, join the discussion at the Eurobricks forum here, and read full details at Lucio’s own website by clicking here.

JCB 5CX Wastemaster | Picture Special

Lego Technic JCB Remote Control

Every so often a creation comes along that shifts what we thought possible from LEGO bricks. This is one such creation. Created over the course of a year by Technic-building legend Sariel this is a fully working replica of JCB’s 5CX Wastemaster backhoe, powered by pneumatics, eleven Power Functions motors, and two third-party SBricks.

Lego Technic JCB 5CX Remote Control Underneath the brilliant Technic exterior are nine motors that drive all four wheels, the three-mode steering (two-wheel, all-wheel and crab), backhoe arm rotation and traverse, and powering a combination of pneumatic cylinders and linear actuators to control both the front and rear arms and their respective buckets. A further two motors power the pneumatic ‘remote control’, compressing the air which travels down twelve separate hoses to the model itself.

Lego Technic JCB 5CX Remote Control

A motorised remotely rotating driver’s seat and a suite of LED lights from third-party lighting specialists Brickstuff complete the electronics, making this 2.4kg, 75 stud-long masterpiece one of the most technically advanced Technic creations to date. There is much more to see of Sariel’s amazing remote control JCB at the Eurobricks forum, on Flickr, and at Sariel’s excellent website, you can watch it in action via the video below, and if you’d like to build your own model with many of the features of this one we highly recommend LEGO’s own 42054 Claas Xerion 5000 set, which share its wheels and amazing three-mode steering with Sariel’s fantastic creation.

Supersized 6668

Lego MAN Container Truck

LEGO’s 6668 Recycling Truck from 1994 is one of this writer’s favourite ever sets. Released during the golden age for LEGO Town it looked great, featured the clear everlasting decals that we constantly wish that LEGO still used, and included a neat rubber-band powered container-hook mechanism controlled via a little wheel on the side.

Flickr’s Krzysztof Cytacki (aka Dirtzone) has channeled this high-point of the Town range and supersized that humble truck, building a remarkably similar-looking MAN F90 hook truck in Model Team scale. Being a big bit for rubber band power, Krzysztof has chosen LEGO’s Power Functions motors and Technic pneumatics to control his hook mechanism, plus his creation features remote control drive and steering, a raising/lowering third axle, and working suspension on all wheels.

Lego MAN Container Truck

It’s a treat to watch in action and you can do just that via the YouTube video below, plus you can check out all of the images of Krzysztof’s MAN F90 truck at his Flickr album by clicking the link above.

Un Petit DS

Lego Technic Citroen DS

DS. The answer to the question ‘I’d like to buy a Citroen, but can I pay more money for one?’ which literally no-one has asked ever. Citroen’s modern reinvention of the DS nameplate, which is now a stand-alone brand, is – frankly – complete bollocks. But it wasn’t always like that.

This is the Citroen DS19, launched in the mid-1950s it looked like nothing else on earth, and it is very probably the car that was, and always will be, farthest ahead of its time.

With headlights that swivelled with the front wheels, disc brakes, a clutch-less automatic transmission, power steering, and incredible hydro-pneumatic self-levelling independent suspension, the DS19 was a technological marvel.

To build one in small-scale Technic therefore, is not an easy feat. However previous bloggee Anto of Eurobricks has done just that, and his little Technic DS looks as wonderfully, unfathomably, complicated as the real thing.

Squeezed inside the reasonable Technic approximation of the DS19’s remarkable shape is a fully functioning pneumatic suspension system, allowing Anto’s model to raise and lower itself as per the real car, plus of course, it can suspend the car from bumps in the usual way that suspension does.

In addition there’s also working steering which, like the real DS19, is linked to the swivelling headlights,  opening doors, hood and trunk-lid, and even a basic interior. How Anto has fitted all that inside we don’t know but you can try to figure it out for yourself via the Eurobricks discussion forum.

Click the link above to jump to the full gallery of images, build details, and a video of Anto’s Technic Citroen DS in action.

Scorpion King

Lego Technic RC Ponsse Scorpion King Forester

The Scorpion King may be a truly awful movie spun off from a merely not very good one (although this TLCB Writer will watch it at every opportunity for one simple reason), but it managed to spawn both an even more pointless sequel and give name to an obscure Finnish forest harvester range.

OK, we’re not really sure if the marketing department at Ponsse actually named their eight-wheel harvester line after a terrible Dwayne Johnson film, but they do share the same name.

This goliath of a model is a fully-functioning Technic recreation of that Finnish forester, and it’s a work of engineering genius. Powered by eleven motors, marthart‘s Ponsse Scorpion King can drive, steer via linear-actuator driven central articulation, raise, extend and turn the harvesting arm, and do whatever-it-is that the thing on the end does to harvest trees, all via remote control.

There’s also an on-board compressor for the pneumatic system, an inline 6-cylinder engine, working suspension, and a detailed tilting cabin too.

There are more images available to view at marthart’s Ponsse Scorpion King album on Brickshelf via the link above, and here’s another bonus pic because something good had to come from that dismal movie…

Slowly Smushing

Lego Technic RC Dakar Truck

It’s been a while since the last episode of Elf-on-Elf violence (even Elven behaviour during this year’s FIFA World Cup even proved uneventful, unlike the last one), however today we’re back to earth with a bump, thanks to this (admittedly incredible) fully remote controlled Dakar rally truck by Lucio Switch.

Driven by four XL motors with a Servo for steering, plus live-axle suspension, pneumatically controlled differential locks powered by an on-board compressor, LED lights and SBrick bluetooth control, Lucio’s Dakar truck is an engineering masterpiece. All of that lot makes it supremely capable off-road, where it can slowly climb over almost anything. Elves included.

Lego Technic RC Dakar Truck

As is the way with heavy remote control Technic models Lucio’s truck is pretty slow, and certainly no match for a fleeing Elf. But if a trap of sticky-side-up parcel tape has been laid by one of the little scumbags, the truck’s slow speed (but massive weight) are – if anything – advantageous to a good smushing.

So cunning was this inventive new use for sticky tape that we almost respect the Elf that did it. Almost. Because not only did we have to collect some thoroughly smushed Elves, they had to be pulled off the parcel tape too, which was not appreciated by them one bit.

We’re now going to look into a more secure stationary storage solution whilst you can check out all of the superb images of Lucio’s amazing creation on Flickr, plus you can join the discussion and watch the truck in action via the Eurobricks forum.

Elven Eviction

Lego Caterpillar D11T Bulldozer RC

All was quite in The Lego Car Blog Towers this morning. The Elves were asleep in their cage room and we were quietly watching the Monaco Grand Prix qualifying, er… we mean working studiously in the office.

And then came the sound of several soft thuds, kind of like a series of bean-bags falling off a table, followed by great Elven rage. Sigh.

A wander down to the cage room revealed the cause, where an enterprising Elf had returned early in the morning whilst its colleagues were still asleep, and promptly driven a remote control bulldozer through the Elves’ cages – much to its own amusement – pushing them out and onto the floor below. Cue the Elven rage.

Unable to escape by riding atop the ‘dozer due to its limited speed, the unhappily awoken Elves had caught their attacker and were trying to feed him into the VHS machine. Mr. Airhorn was deployed to restore calm (which definitely awoke any Elves fortunate enough to avoid the original incident) and we’ve now taken control of the offending vehicle.

Lego Caterpillar D11T Bulldozer RC

And what a vehicle! Based on the Caterpillar D11t bulldozer, Piotr K‘s creation is a superb example of how to utilise both Power Functions and pneumatics.

Two Power Functions L Motors drive the tracks, which are suspended by a pendular equaliser bar, whilst three M Motors power the pneumatic systems, with one driving an on-board compressor (with an auto shut-off) and the other two activating the pneumatic valves. This gives Piotr’s model a continual supply of compressed air to power the huge front blade and the rear-mounted ripper which can be operated remotely via LEGO’s IR system.

It’s very neatly engineered set-up and one that works – as the Elves found out – really effectively. You can see more images and read about the build on MOCpages via the link above, plus you watch the model in action via the YouTube video below.

The Other Challenger

Lego Challenger MT-865 Tractor

The Dodge Challenger has appeared here numerous times over the years. This isn’t that Challenger. Nope, this one is made by Caterpillar, and it comes from a series of tractors that were the first to be specifically designed to run on tracks.

This brilliant Model Team recreation of the latest Challenger MT865C comes from the appropriately-named Eric Trax, who has done a simply astonishing job replicating the Caterpillar in Lego form. And Eric’s creation is far from a static model…

Lego Challenger MT-865 Tractor

Inside the beautifully constructed exterior are a wealth of electronic and pneumatic components, allowing Eric’s Challenger to drive, skid-steer, and power both an on-board compressor and power-take-off.

Hooked up to the back of the MT865 is a Kinze 1050 grain trailer, complete with its own Medium motor and pneumatics to control the unloading auger.

Lego Challenger MT-865 RC

All of these functions can be controlled remotely via bluetooth, thanks to the third-party SBrick concealed within the build. This enables the models to be controlled by a phone or, as Eric has done, by a Playstation 4 controller!

There’s much more to see of this amazing Caterpillar Challenger MT865C tractor and Kinze 1050 grain trailer at both Brickshelf and the Eurobricks forum – click the link to see all of the images and to read complete build details.

Mighty Mercedes

Lego Technic Mercedes-Benz Zetros Truck RC

This stunning looking Mercedes-Benz Zetros 6×6 crane truck is the work of newcomer JRX, and it’s might just be the most technology and feature packed model of the year so far.

Underneath the realistic exterior are fourteen Power Functions motors, fifteen pneumatic cylinders and ten pairs of LED lights. Oh, and a third-party BuWizz brick to provide the power required and control the working functions. Now concentrate, here comes the science part…

Lego Technic Mercedes Zetros 6x6

All six wheels of JRX’s Zetros are independently suspended and powered by four LEGO Buggy Motors, with the three differential locks activated by a Servo motor and four pneumatic cylinders. These pneumatics are powered by an on-board compressor consisting of a Large motor and four pneumatic pumps, which also drive the crane extension and boom lift via a further five pneumatic cylinders.

A Medium motor and a further three Servo motors power the crane winch, rotation and elevation, whilst another Servo, Medium motor and two more pneumatic cylinders drive the outriggers. One final Medium motor powers the front winch and ten pairs of LEDs light the headlights, tail-lights, floodlights, warning lights and flashing turn signals.

JRX’s Mercedes-Benz Zetros has more squeezed inside it than your Mom’s corset, and just like your Mom there’s a video of it action available to view online. You can watch the Zeros is action via the video below, and you can see all of the photos and read further build information at both JRX’s Flickr photostream and via the Eurobricks discussion forum.

Trucavator

Lego Technic Tatra Truck Excavator

We don’t see this type of vehicle in TLCB’s home nation, and we’re not really sure why. A hybrid of truck and excavator it seems like quite a useful design, being fast enough to drive on roads without annoying everyone and diggery enough to do some digging when it reaches its destination.

This pneumatically-powered Technic version is based on a Tatra 815 with a UDS excavator mounted to the rear. It’s been built by newcomer Ivan MOC and it features working steering, a V4 piston engine, suspension on all axles, pneumatic stabilisers and boom elevation, manual boom extension and 360° excavator rotation.

There’s more of Ivan’s build to see at Eurobricks and Flickr – click the links if you dig it.

Candy Crush

Lego Technic Volvo FMX 4x4 Crawler RC

It’s been a slow (read ‘hungry’) week for The Lego Car Blog Elves. However, with their empty stomachs ‘motivating’ them it was only a matter of time before we’d have a creation to share with you.

The hungry Elf responsible for today’s find was duly awarded a meal token and Smartie, upon which something remarkable happened… the Elf ate about half of its Smartie, and it then proceeded to break the rest into pieces. Were we about to witness the first ever moment of Elven compassion and sharing? Were we balls.

The aforementioned Elf scattered the Smartie pieces opposite a curtain in the office and then scurried off. Soon several of its colleagues had sniffed out the unguarded confectionary and landed on the abandoned loot like seagulls on an open bin.

But unguarded the confectionary wasn’t, and the curtains suddenly parted as a huge white truck powered through them. The nearest Elf had just enough time to point and scream before being squashed forcefully into the office carpet, before its scavenging colleagues met the same fate.

A jubilant Elf then re-emerged, scooped up the Smartie remnants, and ran off cackling madly. Sigh. We thought they were getting bored of this.

Still, kudos the Elf in question, which had deployed some remarkable inventiveness to overcome its find’s lack of speed – which normally would have left it unable meet out any smushings.

The vehicular weapon, whilst slow, is a mighty impressive bit of kit though. Based on a Volvo FMX truck, the build features five Power Functions motors that power the four-wheel-drive system, generate air pressure for pneumatically locking differentials, and drive the centrally-pivoted steering, whilst pendular suspension with simply ludicrous articulation and oversize tyres from the 42054 Claas Xerion tractor set take care of truck’s impressive rock-crawling ability.

The build is the work of TLCB debutant dgustafsson1317 and there’s an enormous gallery of high quality images available to view on Flickr. Click the link above to see all of the Volvo FMX Crawler photos, whilst we scrape some very flat Elves out of the office carpet.

Pneumatic Crane Truck – Picture Special

Lego Technic Pneumatic Crane Truck

After a series of small creations we’re back with something big. Really big. Measuring almost a meter long, weighing over 8KGs, and constructed from around 8,000 LEGO pieces, Lucio Switch’s astonishing remote control and pneumatically-powered crane truck is one of the most complex creations that this site has published.

With seventeen Power Functions motors, eighteen pneumatic pumps / cylinders, and six switches, Lucio’s truck takes Technic construction to the limit of what is possible with Danish plastic. Four XL motors drive the rear wheels which are suspended on live axles, whilst the two front axles are steered by twin Servo motors and are suspended independently (which makes for no less than twenty-four shock absorbers in all!).

Lego Technic Remote Control Truck

Underneath the fully suspended and tilting cab (with a working steering wheel, suspended seats and an opening engine cover) is a working V8 piston engine, with twin LiPo batteries that power the motors and six sets of LED lights hidden within the chassis.

Nine M and two L motors then drive everything from the front and rear stabilisers, crane rotation, winch, and the pneumatic pumps which provide air pressure for the three-stage crane elevation and extension mechanism, all of which are controlled via four IR receivers through an SBrick bluetooth device.

Lego Technic Pneumatic RC Crane

Fortunately for us here in TLCB office that lot is much too complicated for our Elves to figure out, so Lucio’s incredible truck was unable to cause carnage and mayhem. It is however absolutely worth checking out, either at Lucio’s Flickr photostream or via the Eurobricks discussion forum, plus you can watch the truck in action via the video below. Prepare to be amazed!…

Two Technic Tractors Tuesday

Lego Technic Case 620 HD Tractor

Today’s blog post is brought to you by the letter ‘T’. Plus the Elves are learning about alliteration, which means that we have not one but two Technic tractors to show you.

They’re both remote control too, which also meant that we had something of an Elven showdown in the corridor this morning. Unable to squash any of their colleagues due to their finds herculean slowness, each Elf decided that the next best route to carnage was to turn their respective machines on one another. Cue the slowest vehicular joust in history, at the end of which the tractors calmly bumped into one another and the Elves at the controls left in disgust.

Well they may not be impressed, but we are, as each build is a masterclass in Technic engineering. Above is newcomer Brick_Sticker’s enormous Case 620 HD, driven by an XL motor and featuring an unusual (but very clever) pneumatic articulated steering mechanism, with an on-board compressor powered by a Medium motor providing the air pressure. Another Medium motor drives a power-take-off, and there are four pneumatic lines where tools could be attached.

It’s a spectacular machine and well worth your click – you can check out all the images and details via both Eurobricks and Brickshelf.

The Case’s gladiatorial opponent in the corridor joust comes from previous bloggee Damian Plesniak, and if anything it’s even slower. Driven by twin Medium motors, Damian’s tracked mini loader features skid-steering, plus a tilting and raising bucket powered by a third Medium motor and an XL.

It works a treat too, and you can see all of the (brilliantly taken) images on Flickr here, plus you can watch a video of the loader in action by visiting the Eurobricks discussion forum.
