Using the left overs from my Battle Bots days, it's basically a Super heavy weight bot, with a mash-up of Johnny 5 / Judge Dredd ABC bolted on top. Plan to add a number of swapable arms with different attachments (water cannon, taser, foam darts, etc). As well as two way radio and camera for interacting with people.
Right now I’m using a simple R/C radio to control the two roboteq Speed controllers.
I’m working on programming a DFRobot Playstation controller and an arduino with 2 xbee chips…but the internet is a bit lacking for tutorials in this area so it’s been slow going so far.
