Elon Musk’s ‘Optimus’ robot prototype unveiled at AI Day 2022 event. Prototype managed to rotate its arms, then tottered to the forefront to give the audience a wave, before walking back as a screen failed to close. ‘I think it will walk in a few weeks,’ Musk said, ‘but we wanted to show you something that’s fairly close to what will go into production’ ‘This is essentially the same self-driving computer that runs in Tesla cars by the way,’ an Autopilot engineer proclaimed. ‘We’ve designed it using the same discipline we use in designing the car, which is to say to design a form of manufacturing such that it is possible to make the robot in high volume at low cost with higher liability’ . . .
