The RoBeetle is a lightweight micro robot powered by methanol.
The RoBeetle is an attempt to create small and efficiently powered robots that can move easily using sustainable fuel source. The lightweight robot (weighs only 88 milligrams) is the design work of Nestor Perez Arancibia, Xiufeng Yang and Longlong Chang at the University of Southern California.
The beetle-shaped robot features four legs consisting of two fixed rear legs and front legs attached to the transmission to receive commands to move forward. The body of RoBeetle is actually a fuel tank and its structure is designed in a way to modulate the flow the methanol by using a purely mechanical system. A full tank of methanol can be used for 155 minutes to make the tiny robot move and perform tiny jobs. There are two little horns that help to carry things more than its body weight. RoBeetle has an unadjustable top speed of 0.76 millimetres per hour and can move only forwards.
