Elon Musk, CEO of Tesla Motors, the prominent electric vehicle company, says one of his next ventures will involve development of a Tesla humanoid robot that will look and move like people. Some robotics experts are skeptical, pointing to many dexterous human physical capabilities that no machines have been able to mimic precisely. Roboticist Heni Ben Amor, a Fulton Schools assistant professor, says the human hand is extremely complex, and that making a robot that could match all of the hand’s skills would be a daunting technological challenge. But Ben Amor says if Musk’s aspiration leads only to a few advances toward his goal, it could still yield significant progress in robotics.
