SMALLBug: A 30-mg Crawling Robot Driven by a High-Frequency Flexible SMA Microactuator
RA-L 2020
We present the design, fabrication and experimental testing of SMALLBug, a 30-mg crawling microrobot that is 13 mm in length and can locomote at actuation frequencies of up to 20 Hz. The robot is driven by an electrically-powered 6-mg bending actuator that is composed of a thin shape-memory alloy (S
