A robotic hand can pick up objects and can adjust the way it holds them when they start to slip. However, adjusting to cope with items that slip (e.g. butter) can be challenging. A recent improvement has made this possible.
The improvement was done by Thomas Thuruthel and his team at University College London. They made a soft robot hand that can keep a shifting object in its grasp with only wrist motions. The soft robot hand is made moulded silicone with flexible pressure sensors on the palm and fingers. The whole device is linked to an AI system. The wrist, which is the only movable part was able to avoid a drop 79 per cent of the time,
