Ages ago, I got sent some very nice 125mm Rotacaster wheels (actually the first to have them) and I built a simple large robot with them.
Now, with the UK's largest LEGO show coming up, I thought I would build something a little bigger.
Work in progress, 2nd version as first version broke when I sat on it!
Its going to look like a car, drive like a tank, hopefully be NXT2WIFI controlled. 13-14 NXT's
When it broke
The main base area supports my weight and moves quicker than the wheelchair, my aim is for this to work outside.
Once I get the subframe finished I post a video!
