large autonomous robot brain and drive system ideas? Answered
So I have been looking at several different instructables and articles online and I'm really interested in trying to build a large robot of my own, similar to but updated and maybe more refined than the robot butler instructable here. Right now though I'm trying to figure out what I would run it off of (computer, micro controller etc) and how to interface the motors with this control system. Wheelchair motors seem to be a great option for the motors and wheels so what sorts of options do I have to interface that with a computer or how could I interface it with just an arduino or something similar? The robot butler instructable used phidgets and several relays to control everything but I'm wondering if there is a simpler or better way. I want to be able to control the two wheelchair motors and wheels as a base as wells as probably several servo motors for the robot's arms and potentially a webcam and some speakers. Any help anyone can give on ways to do this sort of thing or guidance on how to even begin is greatly appreciated. Thanks!
