PORTLAND, Ore. — Ever try to get the lid off a jar with one hand, or open an envelope, or 1,000 other two-handed tasks? Well now you can, that is if you are wearing the new wrist-robot from the Massachusetts Institute of Technology (MIT). Still in the prototype stage, the wearable robot nevertheless offers a new paradigm in assistive robotics called “synergism.”
“It is well known that the motion of the human hand is controlled by synergy — which is the idea that groups of muscles are activated together by a single control signal,” said MIT doctoral candidate Faye Wu in a video about her presentation this week at Robotics: “Science and Systems 2014” (July 22 through July 24 in Berkeley, Calif.) “We want to extend the synergy-based control to wearable robots.”
To do so, the wrist-worn robot has a glove attached that measures the angle and orientation of each finger, then passes a control signal to the extra fingers to react synergistically. For instance, if a large object is being picked up, the normal fingers only need grasp its top while the longer robotic fingers grab its bottom portion.
