Prosthetic Arm Biomimics The Arms Of An Octopus
Kaylene Kau, a recent graduate from the industrial design department at the University of Washington was challenged by a professor to 'push the boundaries of prosthetic design.' So she did, and here, inspired by the fluid movements of an octopus's arms, is her multi-jointed Prosthetic Arm.
Kau's research on prosthetic arms revealed that they are used primarily to assist the dominant arm, rather than to mimic the actions of the dominant arm. Her flexible design enables two important functions of her inspiration, as the octopus arm is great at picking up and holding things of various sizes.
The Prosthetic Arm is fitted to the remaining portion of the missing arm and has a number of separate links which act as joints to enable a variety of bending skills, even a tiny snail curl at the furthest end of the arm to grasp something small.
The Arm is operated by controls located on the upper surface of the device. They direct a motor and cables that run through the Arm contracting and relaxing the joints to enable their actions.
This Prosthetic Arm may not look very lifelike, but it certainly appears to be accomplished. Ms. Kau... maybe you have a career in biomedical engineering ahead of you. Congratulations on both your observations and your exceptional biomimetic design plan.
P.S. Octopuses don't have tentacles.
