Sheldon robot: semi-autonomous motion control node

The overall architecture of the Sheldon robot is going to be modular. Aside from a central computer (probably a Raspberry Pi or some such), there will be multiple computers or microcontrollers each managing some sub-system. And the first of these is for motion control. I decided on this hierarchical approach because of previous experience building robots. Most of these were… Read more »

Sheldon robot: controlling the motors

Many beginners’ guides to electronics teach you how to build motor controllers using mosfets, H-bridge circuits and all that good stuff. And maybe I’ll get around to doing that one day. But to get this robot project up and rolling, I decided to go for an off-the-shelf motor controller. I’ve used many before, including Arduino shields from Adafruit and Snootlab…. Read more »
