If everything goes well, a type of "capsule robot," which can both move automatically in people's stomachs and diagnose illnesses will be put on the market by the beginning of 2011.

Reporters learned on Nov. 7 from the Chongqing Jinshan Science and Technology (Group) that they have successfully developed the world's first moveable "capsule robot."

It is quite different from the traditional capsule endoscopy, which can only move passively along with the stomach's peristalsis. Meanwhile, the Jinshan PH capsule, which is used for diagnosing gastroesophageal reflux disease was also successfully developed by the group, making them one of the only two companies in the world that have successfully developed the PH capsule.

Wang Jinshan, Board Chairman of the Jinshan Group, disclosed that the traditional capsule endoscopy can only "travel through the alimentary canal passively" after being swallowed, but cannot be controlled remotely. The "capsule robot" took the Jinshan Group eight years to develop, and is only one-third the size of the traditional capsule endoscopy, but has integrated MEMS, communications and automatic control technologies.

After a patient swallows it, the doctor can examine suspicious areas of infection from different angles by using the advanced position controller so that diseases can be diagnosed more effectively. The "capsule robot" is sold at a price of about 2,000 yuan per unit.

What will be put on the market together with the "capsule robots" are the PH capsules developed by Jinshan Group. Compared to PH capsules developed by Medtronic Incorporated, one of the Top 500 Enterprises in the World, the Jinshan PH capsule can monitor patients for 96 hours and its price is only a little more than 1,000 yuan.

The Medtronic PH capsule can only monitor patients between 24 and 48 hours and the medical charge for one monitoring is as high as 2,000 U.S. dollars in foreign countries. According to the evaluation, after the Jinshan PH capsule is put on the market, its demand on the domestic market alone will be as high as 2.7 billion yuan.
