An electromagnetic anglerfish-shaped millirobot with wireless power generation

Target clamping and cooperative motion control of ant robots

Carpenter ants possess the characteristics of division of labor, communication between individuals, cooperation, and the ability to solve problems. Inspired by the carpenter ant, we designed electromagnetically controlled ant millirobots that can move, clamp, and work cooperatively. The robot can receive power wirelessly to actuate its ionic polymer-metal composite gripper. Further, two robots can be controlled to manipulate small components individually or cooperatively. Dual-robot manipulation is found to take 76.7% of the time required for single-robot manipulation. The results show that complicated manipulation can be performed by robots that are multifunctional and flexible by utilizing electromagnetic actuation, intelligent materials, and wireless power transmission.
