Tesla's Optimus robot is going through growing pains

Tesla wants to build 20,000 Optimus robots every week. A new report says it is far from that. The Information reports Tesla made 'several hundred robots a week' last month. Tesla turned its Model S and Model X car lines over to robot building earlier this year. Robot parts are much smaller than car parts and must line up very precisely. The hands and forearms alone have over 100 screws and tiny pieces that workers still fit by hand.

Elon Musk has called Optimus Tesla's 'biggest product of all time' and has promised it for years. For now the robots only do limited jobs inside Tesla, and not general work. The company plans to lease them first instead of selling them. Other firms are trying less human-like robot designs. Chinese regulators have also reportedly held back some listings for humanoid robot makers.

Humanoid robots are still far from doing everyday jobs. This shows how hard it is to build robot hands that work as well as our own.
