Why existing robotic hands could not be used for tactile sign language
 |
Tatum Robotics originally expected to adapt an existing robotic hand for DeafBlind users. The problem was that American Sign Language requires precise finger positioning, while many standard robotic hands rely on rigid linkages that can create pinch points. That does not work when a person needs to hold the hand directly to receive tactile signing. The team instead developed a compliant, tendon-driven hand with additional degrees of freedom. DeafBlind users can place their hand on the robot and receive letters through movements designed to closely match a human hand. submitted by /u/Responsible-Grass452 |
