Have anyone of us wondered a nanorobot in the form of a capsule? Researchers at MIT are working on this project and have demonstrated a tiny origami robot that can unfold itself from a swallowed capsule and crawl across the stomach due to external magnetic fields to remove foreign particles. There are robotic surgeries being performed to remove tumors, for kidney transplant, heart surgery, hysterectomy which provides surgeons with better accuracy, flexibility and control. No wonder, robots are the greatest invention of mankind.
