Scientists Invent Battery-less ‘RoBeetle’ that Runs on Methanol
The RoBeetle is just 15 millimeters in length which according to its inventor Xiufeng Yang is “one of the lightest and smallest autonomous robots ever created,” “We wanted to create a robot that has a weight and size comparable to real insects,” Yang added. Priorly, most robots needed motors that are themselves heavy and require electricity, which as a result makes batteries necessary. The most trivial batteries available weigh 10-20 times more than a tiger beetle which is a 50-milligram insect the team utilized as their reference point. To deal with the problem, Yang and his associates invented an artificial muscle system which is based on liquid fuel, in this case, methanol. it stores 10 times more energy as compared to a battery of the same weight. The RoBeetle working mechanism is as follows, The team examined their RoBeetle on different flat and inclined surfaces made from a variety of materials that were both smooth and rough. The mini robot could carry a payload of up to 2.6 times its own weight on its back and can operate nearly two hours on a full tank. Check out?
