Unlike this snake with robotic legs, MIT’s RoboCap might actually save lives in the future.This robotic pill is capable of tunneling through mucus in the GI tract to administer large protein drugs like insulin, thus replacing traditional injections completely.Put simply, this robotic pill has a cap that spins and tunnels through the mucus barrier when it reaches the small intestine, enabling drugs carried by the capsule to pass into cells lining the intestine.RoboCap could also be uased to deliver vancomycin, an antibiotic peptide that currently has to be injected.The spinning cap helps erode the compartment carrying the drug, which is gradually released into the digestive tract."
