This ingestible robot delivers insulin to your body without external needles

Researchers from Italy have created a robot that could one day allow diabetes patients to get a dose of insulin without any needles. PILLSID involves two separate parts. One component is an internal insulin dispenser that a doctor would surgically implant in your abdomen. The other is a magnetic capsule loaded with the hormone. Anytime you need to refill the dispenser, you take one of the pills, and it travels down your digestive system until it reaches the point where the device is implanted near your small intestine.
