One of the challenges of making large stuff is making it move. The past 2 robots had been driven by tank tracks but I thought I would try something else. So I posted on Eurobricks asking about giant wheel designs as Lego don’t make large wheels. I had some awesome feedback and here is the result.
I must actually update the video as it works a lot better now. I have replace the 16 long technic studded beams on the outer rim to be 15 long studless beams so that it does not lock up (clicking noise on video).
I have also removed the front set of balancing wheels and counter balanced the back ones so that it looks more impressive. I will post an update soon.
