LEGO’s 42100 Technic Liebherr R 9800 is the largest Technic set ever produced. With over 4,100 pieces, seven electric motors, bluetooth control and a $450 price tag, we’re fairly sure that most MOCs will be quite a lot smaller than LEGO’s latest Goliath. Cyberdyne Systems hasn’t let that stifle his ambition though, building this tiny mechanical version of the mighty 42100 set and equipping it with all* the functionality of its much bigger brother.
The bucket arm can swing, raise and extend mechanically via linear actuators (and much finger twiddling we suspect), whilst the bucket itself can both tilt thanks to a worm gear and open by pulling on a string.
There’s more to see of Cyberdyne’s 42100-in-miniature at the Eurobricks discussion forum via the link above where you can also find a video of it in action.
