FDA approves lifelike robot arm

Amputees will now have access to a prosthetic limb known as the Deka Arm. The Food and Drug Administration (FDA) has approved the robotic arm, which is so lifelike that it allows a person to unlock doors, use zippers, and pick up utensils for eating.

The Deka Arm is seen as a major improvement over past prosthetic limbs because it has a wider range of movement. Advances in prosthetic arms and hands is lagging behind legs because of the intricate motions of fingers and hands.  The Deka Arm works by using electrodes to detect tiny muscle twitches from the user as they learn to perform the 10 different movements of the limb. It’s designed for people who lost arms at the shoulder, mid-upper arm or mid-lower arm.

U.S. Army veterans helped develop and test the arm and the project was funded by the U.S. Defense Advanced Research Project Agency for $40 million.
