Japanese Telepresence (“Telexistence”) Avatar Transmits Touch, Temperature and Vibration to Remote Operator
The TELESAR V’s hands and fingers are equipped with a number of sensors to capture and relay tactile information to its operator through special gloves. The primary sensor inside each fingertip is a vision-based force sensor which is comprised of a wide-angle camera that looks through a gel-layer mixed with thermochromic ink. When the gel compresses, the thermochromic ink becomes denser, which the camera interprets as force information.
Microphones underneath the robot’s fingertips convert low to mid level vibrations; when pouring marbles from one cup to another (as the robot), the operator feels the tactile sensation from doing so. Furthermore, the operator is able to sense changes in temperature at the robot’s fingertips, thanks to thermoelectric peltier devices which reproduce warm and cold temperature inside the operator’s gloves. Now even an object’s texture can be relayed to the operator.
