Narrator: This is Science Today. Engineers at the University of California, Santa Cruz have developed a prototype of wearable, robotic exoskeleton arms for therapeutics purposes which feature two innovations that distinguish their prototype from other designs. Medical robotics expert Jacob Rosen says one is the ability to allow the user to reach 95 percent of their natural range of motion and the other is a method for using the body's own neurological signals to control the exoskeleton arms.
Rosen: We are trying to anticipate what patients are trying to do and the way to anticipate that is by putting electrodes on the skin. You essentially, with these electrodes, you can sense the signals the brain is sending to the muscles to contract. And the idea is that you can take these signals, you can run in parallel muscle models and you can predict what the physiologic muscles will do in a fraction of a second later.
