This is a Robot I am building, I need to get my Project straight before I release more, but maybe someone is interested already.
Robot uses PI and arduino nano, l298n motor controllers, a self written, ros serial based motor controller and a hall sensor based magnetic wheel encoder, self designed, but unprecise as i attached it to the front gear. I will change that. gearbox is self designed, everything 3d printed.
Mounts this pi3 case:
Uses a powerbank to power itself.
Uses CDrom motors, same as in my fidget spinner project.
Complete robot is 5 volts.
Robot runs on ROS Kinetic on Ubuntu Mate ARM on pi 3.
gearbox is 3d printed and uses 6700ZZ bearings.
otherwise only m3 and m4 screws are needed. And two cdrom motors one l298n, pi camera, powerbank (check size on model with usb),2x hall sensor,2x resistor,cables)
