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.

Hazbot fantastic! that time has its battery autonomy? Lipo is a 2 or three elements? how many milliamps?
R2D2, for his trip up to the letterbox and back Bob used the battery that came with the tank, a 7.2 volt 1700mah Nicad Battery pack, whilst his EZ board and servos run off a 11 volt Lipo with a 6 volt regulator.
On the subject of batteries, my research points the same direction as the advise given from Bobs tech support crew (Richie - RC and Robotics ) - Lipos are the way to go. They are light, can punch out the amps and fast charging. You do need to nurse their charging with a quality charger that balances the cells but they more than make up for any down side. I learned how good they are through RC aeroplanes and helicopters. Eventually Bob will have 3 seperate Lipos (Board & Servos) (Tank from H-Bridge via board) (Tank direct via RC Transmitter).
HAzbot, Bob really turned out Great! If you don't mind sharring your script with me, i would like to see it. My Marty (George-ous) is all working great accept Object avoidance.
Thanks,
Mel
Cheers Moviemaker, I'm in the process of testing a new H-bridge on Bobs Tank base. once I install it and get his radar working again I would be glad to share the script but it's nothing fancy. Simple Ping collision detection should be working for you, I had no real problems. As you would know - you need to tweak interval and distance in the config menu and be sure the sensor has a clear scan range (so it's not picking up any edges of the robot as it scans out).
Thank You, my friend.
Woo hoo... He did it
Ok MovieMaker, This could be a case of der..Hazbot.. I know that anyway and I'm not sure about using the camera with script to be autonomous but to run autonomous with ping I have to have Radar Scan, Ping collision and ping distance all running. Once running I just use the Movement Panel to start him forward and he just keeps going, roaming around and avoiding things. I have reverse back before turning checked in the Radar Scan control and Bob reverses back away from chairs and tables with no problems.
Bob went to the operating table today to have his motors H-Bridge enabled. No fancy switches at the moment, just simple connections to enable him to go from RC to EZ. The operation was a complete success.
