Medical researchers in Japan have developed a prototype* miniature* robot that can be used to perform medical procedures deep inside the body. The prototype is the result of three years of work by researchers from Ritsumeikan University and its partners.

The tiny beetle-shaped robot which weighs five grams and measures two centimeters in length and one in diameter, can be inserted through an incision*.

It incorporates* various medical devices including a small camera, sensors* and a drug delivery injector*, which could reduce the need for surgery. Data is sent to a computer through a slim cable and researchers are hoping to develop a transmitter*.

Previously miniature robots designed for inside the body use have been made to be swallowed and can only take pictures, however U.S. researchers are also working on a small robot that enters though an incision to treat heart problems. (SD-Agencies)
