Taller Pete

I made this yesterday and took him out for a walk but he was not balanced as well as the original Pete so he couldn’t really take more than a full step. I thought he looked cool though and it may be worth trying if you have better servos than the 645s I was using all around.

I took it apart today and built a Scout since I got my torso kit the other day. I’ve always loved the Scout and had to build one finally after all these years of seeing the pictures.

I know you said it is gone now, but just thinking about the pics it seems like it would have a very high center of gravity, which may be why it was difficult to balance. If you go back to the design at some point in the future it might be worthwhile to experiment with splitting the batteries (two smaller packs vs. 1 large one) and placing them on the shins or even the feet if you can manage it. :slight_smile:

I thought about doing that but think I was looking for an excuse to build something new :smiley: It was actually strong enough to stand and walk but would probably struggle to kneel or bend much with the 645s. Without arms, he would probably do OK though. I think with 5645s at least in some of the leg joints, he would probably be fine. My code was very rough and the high COG really amplified the imprecision. It’s also why I wanted to work with a Scout for now since it can at least crouch down and be stable.

Oh, and the battery was up that high because I was too cheap to buy him a real head :laughing:
