The smallest quadruped robot is the Harvard Ambulatory MicroRobot with RF Communication (HAMR-F), which weighs only 2.8 grams (0.098 oz) and measures just 45 mm (1.8 in) long. The robot was demonstrated by researchers from the John A. Paulson School of Engineering and Applied Sciences at Harvard University (USA) and the Department of Aeronautics at Imperial College London (UK) in September 2017.

HAMR-F is the untethered version of HAMR, a robot that has been under development at Harvard for several years. The latest tethered variant of HAMR weighs only 1.43 g, and there is another, slightly heavier tethered variant (~1.6 g) capable of walking on water using electro-static foot-pads.
