The Robotics and Mechanisms Laboratory (RoMeLa) of the College of Engineering at Virginia Tech has developed a unique robotic hand that can firmly hold objects as heavy as a can of food or as delicate as a raw egg, while dexterous enough to gesture for sign language.
Named RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments), the fully articulated robotic hand is powered by a compressor air tank at 60 psi and a novel accordion type tube actuator. Microcontroller commands operate the movement to coordinate the motion of the fingers.
“This air-powered design is what makes the hand unique, as it does not require the use of any motors or other actuators, the grasping force and compliance can be easily adjusted by simply changing the air pressure,” said Dennis Hong, RoMeLa
