I'm over at Cal Poly SLO doing a project where I'm going to design a spherical robot. This is my first robot design, however I have worked with a Motorola MC6811 MCU a bit (yes, I know its old school), worked with steppers, and dc motors a little. I've decided that I'm not going to use the 6811 and the Mini Board 2.0 that it came with because I'm having finding a programming environment for windows and there's not much documentation or support for this chip/board combo. I'm thinking of going with an Atmel MCU, but would like a board combo.
Drive 2 hacked hobby servos, 1 DC motor, and 2 optical encoders.
Small in size, free software, USB support, and can interface with a radio controller.
Ideas. I have 4 weeks to get this thing going.
