The pill, which contains a tiny camera, is also fitted with tiny legs that can be activated remotely once it is inside the colon or intestine. The legs protrude outwards and are movable in order to make device to ‘crawl’ inside the patient like a spider. It can be moved back and forth, giving doctors more flexibility during the examination.
