Easton LaChappelle, a high school sophomore from Colorado, built a wireless animatronic hand and entered it into his local science fair. He won first place with the device, which he controls with a glove worn on his hand. The animatronic hand mimics the gloved hand’s finger movements in real time to pick up objects.
