This is Bob, our 3 ft tall house robot using the Ez-Robot kit and leftovers from plastering angle beads (lengths of perferated coated- right angle tin use to finish edges of plasterboard).
The angle beads are super cheap, can be cut to any length and can be easily riveted together. The big plus is the material is super light but strong. Bobs head comprises of 2 X 1.25 ltr plastic bottles. We are soon to retrofit Bob with Electric drill motors so he can venture up the driveway and down the street.

Gasp, Bobs tank base only got posted today - the wait is frustrating me and the Robot
(Bob without Legs/Wheels)
Poor Bob.
This is the hardest part for me. Waiting for parts. I have no patience.
Still waiting ...AAAAAAAAAAAAAAAhhhhhhhhhhhhhhhhh !!!!!!
Me too. It's poopie isn't it? Ugh....... Has it at least shipped already?
They sent an email saying it was shipped Tuesday (3 days ago) - There is no telling when it will turn up and that's the frustrating part - meantime I'm experimenting with arms that can grab things -
Whilst waiting for his legs (tracks) I've added arms and claws but having issues running 6 servos through the board (Bob gets the jitters) - even blinks out at times. I think it's power related. Is there a simple way to run the servos from a H bridge or a voltage regulator ? UPDATE - Richies tip to run a pc fan over the board fixed everything - pretty sure my problems were from the board overheating - no there are no shakes and Bob is back to behaving whilst running off the 11.1 Lipo. looking forward to stronger servos for Bobs shoulders.
Bobs latest photos
Bobs head - removed the plastic bottles and now his head is much lighter and stable
Strips of perspex hold Bobs head in place
Perspex is so handy and easy to glue, rivet or screw to the frame.
The CD's help keep his arms rigid.. They are still work in progress
Bob from above
This PC fan makes all the difference - running him off 11.1 volts with no problems - fan is direct to battery.
