MIT researchers have developed techniques that enable a bug-sized aerial robot to sustain severe damage to the actuators, or artificial muscles, that power its wings.
They optimized these artificial muscles so the robot can better isolate defects and overcome minor damage, like tiny holes in the actuator.
Their repair methods enabled a robot to keep flying even after the researchers cut off 20 percent of its wing tip.
Researchers developed new techniques to repair damaged DEAs that would have been broken beyond repair.
They used electroluminescent particles in the actuator to see if they had successfully isolated a defect.
Even with damaged deAs, the repair techniques enabled the robot to maintain its flight performance, with altitude, position, and attitude errors that deviated only very slightly.
