taking him for a test spin

A project log for R8-D8 - a distant relative of R2-D2

a 12cm radius, 3d printed R2-D2 with some motors, servos and blinky stuff that follows lines, persons or just drives around via bluetooth

So 5V from one source seem to work just fine - a pcb might help correct loose wires an hot-glue mess ;)

I designed 2 iterations of rolls for the front but finally bought one on eBay for 5 Euros.

Hah! Was wondering if you ever got it working... looks good! No more power/noise-issues?

  Are you sure? yes | no

I had him running round a bit with the OSHPark L293D board, but the app I used to control it over bluetooth was sending some weird stuff so it was unrecognizable and the front roll got stuck and was actually more breaking than rolling. So I ordered the metal ball thingy which can be seen in the picture and installed it the day before yesterday. I controlled it via bluetooth serial terminal, just sending 't', 'r' and 'l' as characters.
