A preliminary question before suggesting products / categories: Will the robot be a sumo type and/or do you need it to push other robots?
Also, do you have a general design? Two / four / six wheels or tracks? Can you provide a drawing or sketch?
Any and all additional details would be helpful.
if you could also suggest wheels as well. This is for a 220 pound wedge bot. It would need to push other 220 pound robots. I would also need a LED power indicator light.
You will need really powerful motors and wheels, and a controller to go with it.
Do you have access to a machine shop? Do you have a budget in mind for the robot?
You will really need to draft a design before choosing specific parts.
For the record I do have access to a machine shop. On top of that a buddy of mine is going to do the CAD work for me ( tried it myself once couldn’t get the hang of it). I was told I would need to choose the parts before the designing could be done.
Four CIM gear motors may work, but 220 pounds, pushing against another robot takes quite a lot. You might need to choose something even more powerful, which unfortunately we do not carry at this time.
