What is Tesla’s Optimus robot? While tech like robotaxis is closer to becoming a reality in London, humanoid robots in the home also seem more plausible. According to Musk, the solution will be the Optimus robot, or Tesla Bot as it is also known. Musk said last year that an Optimus robot will be sent to Mars in 2026 on a SpaceX rocket. Home robots are already available from other brands like Neo, whose humanoid robot can be yours for £15,000.
