If a gripper misses its mark, it's back to the starting point, where the controller must map out a new plan. > Looking to give robots a more nimble, human-like touch, MIT engineers have now developed a gripper that grasps by reflex. Rather than start from scratch after a failed attempt, the team's robot adapts in the moment to reflexively roll, palm, or pinch an object to get a better hold. It's able to carry out these "last centimeter" adjustments (a riff on the "last mile" delivery problem) without engaging a higher-level planner, much like how a person might fumble in the dark for a bedside glass without much conscious thought.
