In this month's Servo, in the "Menagerie" section, there is a picture of a cool-looking robot that's humanoid from the waist up, but on a three-wheel base. It's inspired me; I'm thinking that something like that would be great for working the crowd at robot events, especially ones held in public places (malls etc.), where it could easily entice passers-by to stop in and see what's going on.
I've also long wanted to make an R2-D2-style robot, and have even gathered up some pretty powerful motors, but I'm totally stymied at building a chassis and mounting the motors to it, and wheels to the motors. I'm a software engineer; this mechanical stuff is hard for me, and the base seems to be the hardest part.
All this has me thinking: is there something I could cannibalize to make the base of such a robot? The one pictured in Servo almost looks like it might be such a stock item (or if it's custom built, it's very well done!). I've poked around, and looked a bit at motorized wheel chairs and golf caddies, but neither seems quite right. Is there something else I should consider?
Thanks,
