Direct Drive Motors Make Robotic Touch More Human

Direct Drive Motors Make Robotic Touch More Human

The challenge of creating human-like robotic fingers may have just been solved. Continued development of motion control for robotic fingers and hands offers the promise of greater flexibility, especially for automated assembly applications -- and the ability to perform the same work as human hands. The availability of much higher torque, compact motors has been the obstacle, but now new direct drive servo technology and a “partial” motor concept is moving toward a solution. “If you look at the design of robots, they have a shoulder and forearm but not an ability to add hands and fingers,” Ed Neff, president of SMAC Moving Coil Actuators, told Design News during a recent interview. “Designs don’t offer that flexibility and instead have grippers, most of which are pneumatic, because there has never been a commercial robotic finger or robotic hand.” Robotic finger using small...
