This intriguing looking vehicle is an ARGO 6×6 XTV and, just like your Mom at a free buffet, it’ll climb over almost anything to get where it wants to go. The real ARGO is a fully amphibious vehicle, floating with its body above the water and propelled by its six wheels that sit below the waterline. Those six wheels are all driven and are skid-steered thanks to a set of brakes on each side, allowing the ARGO to turn in its own length.
This brilliant little Technic recreation of the ARGO XTV is the work of newcomer Andrew Millson, and whilst his version might not float it steers in exactly the same way as the real thing. In Lego form it would have been far far easier to skid-steer via the use of two motors, one driving the three left wheels and another the three right, but just like the real ARGO Andrew’s model uses a single motor and an ingenious left/right braking system that activates when the handlebars are turned. It’s seriously clever stuff and one of the neatest Technic tricks we’ve seen his year.
There’s more to see of Andrew’s ARGO and the brilliant braking system within it at both Flickr and the Eurobricks forum, and if you’d like to see what Jeremy Clarkson thought of the 8×8 version click here!
