1. I have a new circuit board that does the bot location and orientation. It has GPS, a compass, 3-axis accelerometer, 3-axis gyros, and a barometer. All on a board 4.5 cm x 3.5 cm (roughly). The design will shortly be available on the ranarchy.com pages. Also, the bare boards will be available to the public at Cheap Dirty Boards.
2. The LED controller to drive the leg servos didn't work out. Instead, I'm making a board using 18 one-shots and a good-ole 555-timer (with digital pots to control the servo pulse-width) that should drive the six legs of the BuckyBot.
3. Extruder for the bot is almost complete. Most of this development will be parallel with the rest of the effort.
