Re: If you have questions or comments post here!
3 wheel robot? or 3wd? slight difference. 2wd but with caster may be called a 3 wheel robot. a kiwi drive/killough platform 3wd robot would be really sweeet. a couple teams have already succeeded with those designs. and unstable.. well not necessarily. as loing as you have a nice big triangle it shouldnt be too unstable in itsself. just maybe a high cg will be bad. but that applies to all robots. and yes, as someone said. dont use swivel casters. omniwheels. skids, ball transfers, are a couple better options. but make sure if you use anything of the sort make sure they can support the weight. we destroyed a couple of our 'wheeliebarish' casters.
