The Harvard Ambulatory MicroRobot (HAMR) is a 1.3g quadrupedal robot manufactured using the PC-MEMS fabrication process and assembled using techniques inspired by pop-up books. Using six piezoelectric actuators, HAMR is capable of tethered locomotion up to 37 cm/s using a 70 Hz gait frequency. In addition, HAMR can successfully carry greater than 1.3g of additional payload, and maneuver using two simple control inputs. A previous prototype integrated power and control to demonstrate autonomous locomotion of a 1.7g walking robot.
HAMR was developed in the Harvard Microrobotics Lab and was funded by the NSF and Wyss Institute for Biologically-Inspired Engineering.
