Hello this guys, the above is my testing platform that I have been working on for the past two weeks or so. The only cool nerdy name I was able to come up with is R.A.I.D ( Robotic Artificial intelligence device.)
With the 4 D batteries, It is pretty heavy, walk to slow to roam around the house freely as a reasonable speed, So I added track wheels (Dagu Rover 5), awesome grip.
Need you guys opinion, should I take a step further and remove the Robosapien Legs to reduce weight? Also plan on replacing right arm with an actual robot arm.

Im currently testing,, but will eventually harmount the body into the chassis debating on the legs leave it to preserve the humanoid look, chop it off to reduce weight?

Cool! In my opinion, you don't need the extra weight of the legs so take them off.
I agree, but will have to create a voltage divider circuit. Each leg carry 3V of batteries power, which total to 6V. Tomorrow I will test the amount of current going to the circuit. I have 3x 9.6 rechargeable R/C cars batteries, and two 7.2V R/C batteries. Two of the 3 9.6V will be in parallel to increase the hours of operation, it will power EZ-b H-bridge, camera. I can use one of the 7.2V with a voltage divider along with resistors to power Robosapien upper half, should do the trick.
Seems like that will work.
I like it a lot, great job. If you were to remove the plastic it would be like C3PO in SW episode 1.
My little guy drinking too much juice. I am currently using two 9.6v batteries in parallel, lucky if I get about 30 min of play. Here is a list of thing all being power at the same time.
H-bridge, EZ-B, camera, Rover chassis, robosapien. I have a couple of voltage regulators coming in the mail, but still need to come up with a better power source for this little guy. Can't be a security robot and pet annoyance if can't stay charge:D.
any recommendation of a good small light 12v batteries.
Look at R2D2's first post.
