What do you do when you're in the MINDSTORMS booth at the FLL finals with plenty of robots around? Well, it might lead to some strange combinations. At some point I got the idea to combine a NXT Segway with omniwheels so that it could move sideways. In theory, this shouldn't have any influence on the robot's balance. See the practical experiment Xander and I did below.
Maybe I should patent the idea... If you motorize the sideway motion, Segways become even more capable of moving in narrow spaces.
Also, I wanted to try how well a Segway would perform on a randomly moving platform. This worked quite well, until you reach unexpected holes in the road. Pointless experiments, maybe, but certainly fun to do!
