Yes. The difficulty is that the more joints there are, the more possible solutions there can be.

- k__ 9y agoI see, but are all valid? I have the feeling my hand/arm works like this and always does it the same, probably so the least work is required?
- pgorczak 9y agoOur arms have an entire subspace of possible solutions (you can move your elbow around while keeping your hand in place). In robotics, there are a couple of measures that can be minimized/maximized while computing inverse kinematics. Work is one of them but also time to reach the goal configuration or its "dexterity" for moving on in a future command.
