Deeper sensors for haptic interaction.
A Flexible Way to Grab Items with Feeling
MIT News, Rachel Gordon, April 15, 2022
The Massachusetts Institute of Technology's Edward Adelson and Sandra Liu have developed a robotic gripper with flexible fingers that can manipulate objects using touch sensors that can equal or surpass the sensitivity of human skin. The gripper employs two fin ray fingers, and the researchers hollowed out the inside to fit a camera that faces a layer of sensory pads made of silicone gel affixed to an acrylic sheet. The sheet is attached to the plastic finger piece at the opposite end of the inner recess, and the finger will seamlessly enfold an object. By measuring the silicone and acrylic sheets' exact deformation, the camera and accompanying algorithms can compute the object's shape, surface roughness, and spatial orientation, plus the force being applied by, and imparted to, each finger. ...
