Re: Arm swings when turning, how to brace it?

Our arm twisted a bunch the first time we built it, we found the weak points and redesigned them, and now it twists a bit, but it's acceptable.

But we used tubular materials for the long parts.

If you can use the robot, and it doesn't get damaged by things moving around, then some deflection is acceptable.

Did you ever sit in an airliner and watch the wings bounce up and down?
