Scientists have used a tiny capsule robot to successfully perform intricate manoeuvres inside the large intestine. <br/><br/>The capsule is guided by an external magnet attached to an 18-millimetre robotic arm.<br/><br/>Researchers hope the capsule robot could be used safely and effectively in the future on humans to identify and remove pre-cancerous lesions and tumours detected during colonoscopy.<br/><br/>Colonoscopy is a test that allows doctor to look at the inner lining of the large intestine.
