It's just a concept right now but I wanted others to see that the scale doesnt quite match. Right now its just stacked on there and neck is a little too long.

Have you thought about a wheel hub bearing? $19.90 free shipping on ebay

Hub Bearing

Thanks for the links Dave and rgordon! I think a high quality lazyrobot would be cheaper and less vertical height....though the wheel bearing is ultra strong! ...Troy , I am sure you'll post a vid !with! the arms and head:) when you can

@irobot58, I sure will. Some things are just trial and error.

@rgordon, the second one looks promising because its open in the middle. The other two won't work because I need to have a hole in the center for the center axle with sprocket to come through.

Update: I just ordered this one. I think it will work fine and it's only $10 total.

I decided to sketch out a new frame where I can get the batteries as low as possible and still access them.

@Troy keep up the good work! are you using a jigsaw to cut the ABS? if so make sure you use the correct blade(I am sure you know that!)
