I’m putting together a two-wheeled bot using a Sabertooth 2x12 to control the motors (via a serial connection). At the moment I’m remote controlling it via WebSockets over wireless. I’ve got an Edimax USB wireless adapter that doesn’t seem to draw too much. I’m powering my BeagleBone Black through the Sabertooth from a 13.2V LiPo, the Sabertooth has a 5V, 1A output that is perfect.
BeagleBone code is all written in Python using the Adafruit_BBIO library.
Client side is HTML/Javascript (Bootstrap, JQuery and a bit of glue code).
I’ve got some rudimentary obstacle avoidance working on both the BeagleBone side and also on the Client side on receipt of a message from the BeagleBone.
What sort of distance resolution/accuracy do you get from your range finders and are you using the PRUs for precise timing, or just using GPIOs?
