Hi, I'm calling out for help in selecting motors for a graduation project for my elecric mechanics course. I'm planning on building an R2D2 (Star Wars) robot, driven by 2 motors, controlled by motor drivers and picaxe controller using R/C controller/reciever). The dimensions i have in my head are about 35cm height(14"), 25cm width(10") including legs, leaving us with about a 20cm(8") can. I currently have in mind some geared motors(low amps) so weight should be around 2kg(4lb). I plan on add a few things in the future, like a spinning head, sound system, led's etc.
