A team of researchers from MIT have developed a tiny origami robot that can perform specific tasks inside the body. The robot is sheathed in pig intestines, similar to those used in sausage casings, and unfolds itself for action once it enters the body. When the ice capsule delivery system melts on its way to the stomach, the robot unfolds and can then be controlled by an external magnetic field. Foreign substances can be picked up by the tiny robot and removed through the digestive system.
The creators hope to advance the robotic technology by adding more sensors so that it can control itself independently, eliminating the need for an external magnetic force. Click here to read more about the origami robot in MIT News.
