Tesla robot slowly walks on stage at AI Day

Tesla revealed on Friday a prototype of a humanoid robot that it says could be a future product for the automaker. The robot, dubbed Optimus by Tesla, walked stiffly on stage at Tesla's AI Day, slowly waved at the crowed and gestured with its hands for roughly one minute. Tesla CEO Elon Musk said that the robot was operating without a tether for the first time. Robotics developers often use tethers to support robots because they aren't capable enough to walk without falling and damaging themselves. The Optimus' abilities appear to significantly trail what robots from competitors like Hyundai-owned Boston Dynamics are capable of.
