Imagine that you are designing a two-segment robot arm that has the sole function of bending and straightening at a single joint. When designing the robot joint, which joint in the human body would you try to copy?
What features would your robot joint share with the biological joint? Would mobility or stability be your priority?
What will be an ideal response?
While varied answers might be acceptable, one imagines a uniaxial hinge joint that resembles the elbow. It should be highly stable and designed with features that minimize friction and provide an effective fulcrum.
