Here is a project that involves 3D printing a robot hand powered by NVIDIA Jetson Nano. The Robot Nano Hand has tendon driven fingers. It also comes with AI vision system. It has 4 independent fingers and a partially opposable thumb. Each digit can rotate from side to side at the knuckle.
This robot hand has 11 degrees of freedom in total. Each finger can pinch and handle small objects. The above video gives you a better idea how this robot hand works. This is a project by Rob Knight from therobotstudio.
