Capsule Robots

The capsule robotCapsule robot is an intelligent miniature tool that can enter the human gastrointestinal tract for medical exploration and treatment, and is a new breakthrough in medical technology for in vivo interventional examination and treatment. It comes with a camera (image sensor), microchip and wireless transmission device. After being taken by the patient, the capsule robot can rely on the peristaltic movement of human stomach and intestines or external field energy to move in the gastrointestinal tract and take pictures of the gastrointestinal tract from multiple angles to record the subtle lesions in the digestive tract and gastrointestinal tract for the doctor’s diagnostic reference. After the examination, it is automatically expelled through the digestive tract (Zhi in Mod Phys Knowl 4:75, 2011). Capsule robot applied in the clinic can reduce the pain of patients, shorten the recovery time and reduce the medical cost.
