We investigated the finger design and kinematics, mechanical joint coupling, and actuation methods of these commercial prosthetic hands. The empirical findings are supplemented with a compilation of published data on both commercial and prototype research prosthetic hands. We discuss numerous mechanical design parameters by referencing examples in the literature. Crucial design trade-offs are highlighted, including number of actuators and hand complexity, hand weight, and grasp force.
  The fibula is commonly known as the calf bone. It's the weight-bearing bone that extends to the ankle from the knee. It runs parallel to the tibia, which does is not w â¦ eight-bearing.he fibula is connected by a synovial joint to your other shin bone, the tibia. The â¦ fibula is what makes your outer ankle bone. And the tibia makes your inner 'ankle' bone. The main job of the tibia is to form a hinge joint with the femur, which allows you to walk, run, kick a ball, and generally have fun.
The fibula is the long, thin and lateral bone of the lower leg. It runs parallel to the tibia, or shin bone, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg.Compared to the tibia, the fibula is about the same length, but is considerably thinner.he fibula is the long, thin and lateral bone of the lower leg.
