To develop an untethered, autonomous, insect-scale soft robot powered by low-voltage dielectric elastomer actuators capable of carrying its own electronics and power source.
Engineered low-voltage stacked dielectric elastomer actuators (LVSDEAs) operating below 450 V to drive a 40-mm-long, three-legged soft robotic body weighing 190 mg.
Fabricated and integrated a 780-mg flexible printed circuit board carrying optical sensors, a microcontroller, a battery, and dual-channel drive electronics delivering up to 450 V at frequencies up to 1 kHz.
The unloaded 190-mg robot achieved a locomotion speed of 30 mm/s and supported payloads up to 950 mg, exceeding five times its body weight.
The integrated subgram robotic platform successfully performed autonomous navigation by independently tracking printed trajectories.
