Robotic manipulators that may offer high gripping force in hazardous environments still would like delicate management - and what higher thanks to offer that management than directly from somebody's hand? that is the thinking behind ExoHand, a prosthetic developed by Festo of Germany - a veteran maker of robots - and modeled by activates the herring gull, penguin or maybe the elephant's trunk.
ExoHand could be a pneumatically-driven exoskeleton that matches the hand of the user sort of a glove. The operator's hand movements are detected and then transmitted to a robotic arm that controls its own version of the hand.The glove is created to suit the human operator perfectly; a scan of the user's hand is created and a 3D printer creates the ExoHand in polyamide plastic. Eight pneumatic actuators move the fingers, so they will be opened and closed.
As the video on top of shows, the hand permits pretty precise movements to be transferred to the robot glove. higher still, the system will amplify the force the user exerts to confirm, as an example, that crucial items aren't dropped. The user conjointly feels what the robot feels through force feedback via two-way pneumatics, in order that they do not overdo it.
Festo, however, is way from alone in doing superb things with automated hands. Prosthetics firms like bit Bionics in Livingstone, UK, have built some astonishingly lifelike bionic hands with independently motorised fingers and joints that have totally modified the lives of these who use them - permitting them to tie laces or develop objects with nearly natural dexterity.
