École polytechnique fédérale de Lausanne (EPFL) researchers in Switzerland have developed an innovative robotic arm with a detachable hand that can crawl around and grab things. This required refining the design using a genetic algorithm and testing it in the MuJoCo physics simulator.
This genetic algorithm and tests enabled the researchers to determine the optimal position as well as number of articulated fingers needed. A magnetic connector at the wrist allows it to attach and detach from an arm autonomously. Its fingers can bend in both directions to help the hand lift objects while the rest function as small legs.
