Self-righting mechanism

As of 2016, the U.S. Army Research Laboratory (ARL), based at Aberdeen Proving Grounds, MD, developed self-righting robots for bomb defusal and reconnaissance.

[5] Cockroach exoskeletons inspired researchers to manufacture a robot that can move around rapidly in both open and confined spaces with self-righting capabilities.

[5] In 2016, ARL and its collaborators published additional research, "Cockroach-inspired winged robot reveals principles of ground-based dynamic self-righting", demonstrating a bio-inspired design.

[6] Biohazard was the first robot to self-right in combat, against Vlad the Impaler in the 1996 tournament, however since the match had ended it made no difference to who actually won.

The next year Vlad the Impaler fought Biohazard again, and the former used its special pneumatic lifting arm to self-right numerous times, yet it still lost the judge's decision.

These varied in design and effectiveness; examples include Razer's side wings, Hypno-Disc's srimech bar and Panic Attack's top lid.
