Researchers at the Massachusetts Institute of Technology (MIT) Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a robotic system in which machines help people lift objects by monitoring their muscle movements, producing a smoother robot-human collaboration.

The system, called RoboRaise, involves putting electromyography sensors on a user’s biceps and triceps to track muscle activity. Then, algorithms continuously detect changes in the person's arm level, as well as minute up-and-down hand gestures the user might make for finer motor control.

During testing, users worked on tasks with a robot and were able to control it to within a few inches of the desired heights by lifting and then tensing their arms.

The system was more accurate when gestures were used, with the robot responding correctly to about 70% of all gestures.

Said CSAIL director Daniela Rus, "Using muscle signals to communicate almost makes the robot an extension of yourself that you can fluidly control."
