CHAMPAIGN, Ill. — Robots perform many tasks that humans can't or don't want to perform, getting around on intricately designed wheels and limbs. If they tip over, however, they are rendered almost useless. A team of University of Illinois mechanical engineers and entomologists are looking to click beetles, who can right themselves without the use of their legs, to solve this robotics challenge. The researchers presented their findings at Living Machines 2017: The 6th International Conference on Biomimetic and Biohybrid Systems at Stanford University, and later won second place in a student and faculty research competition at the international BIOMinnovate Challenge, in Paris, France - a research expo that showcases biologically-inspired design in engineering, medicine and architecture. "This idea came to life when a group of insect physiology students decided to take a closer look at what makes click beetles jump as part of a class project," said department of entomology research scientist and study co-author Marianne Alleyne. The beetles have a unique hinge-like mechanism between their heads and abdomens that makes a clicking sound when initiated and allows them to flip into the air and back onto their feet when they are knocked over, Alleyne said.
