We present the shape-memory alloy (SMA) robotic traveling insect (SMARTI), a 60-mg crawling microrobot that is driven by two 6-mg high-frequency SMA bending actuators and whose two-module configuration enables controlled differential steering and path following. During operation, the two modules are
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
We introduce Bee <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> , a 95-mg four-winged microrobot with improved controllability and open-loop-response characteristics with respect to those exhibited by state-of-the-art two-winged microrobots wit
