HiTechnic Rotacaster

For those of you looking for the perfect third wheel for your robot design, look no further. These omni-wheels allow smooth movement in every direction and don't have the annoying effect caused by a caster. During my four years on an FLL team we experimented with many forms of third wheels and I wish we would have been able to use these, but unfortunately they are not made be LEGO and not allowed. But for those of you just using them for fun, I have bought then and tested them and do not fail to amaze. Please take a look at HiTechnic's Rotacaster.
