Imagine: You accidentally swallowed the battery. To get it out, you need to take a tiny robot. Researchers from the Massachusetts Institute of Technology, the University of Sheffield and the Tokyo Institute of Technology have developed a new origami robot that transforms into your stomach. Embedded in the middle there is a magnet that allows you or your doctor to control from using another magnet on the outside. It also removes the battery or seizes other objects inside your stomach.
The LED lens itself is a precision optical accessory, so it has extremely high requirements on the accuracy of the mold, especially the processing accuracy of the lens optical curved surface must reach 0.1μm. Generally, the following equipment must be provided for the processing of such high-precision molds: ultra-precision processing machine, CNC comprehensive processing machine, precision grinder, precision milling machine, drilling machine, CNC precision spark machine, surface profiler, interferometer, etc.

This new design is a follow-up to the old origami robot. It has a completely different design and uses its corners that can stick to the stomach surface to push itself. The team decided to focus on battery retrieval because in the United States, people swallowed 3,500 coin cells alone. Although they can be properly digested, they sometimes burn the stomach and esophagus. This robot can be easily taken out before a person's organs are in danger.
