LEGO BOOST Tracked Excavator
LEGO BOOST gets dirty!
I really broke the rules this time! I put this LEGO BOOST Tracked Excavator on real, dirty sand and controlled it to dig!
Watch this amazing LEGO Excavator move its boom and bucket, just like a real building site machine. I designed a mechanism that allows a single motor to give the boom this realistic motion thanks to cranks and levers.
Wanna start at once? Here are the instructions for the base of the excavator for free!
