Musk then brought out a much more recent prototype of Optimus. In fact, it’s the first version of the robot that Musk hopes to launch commercially. It’s capable of moving all of its fingers independently, with opposable thumbs on both hands with two degrees of feedback. Sensors are inside the hands, controlled by a computer actually built into the hand itself.
That means the hands can keep track of where they are in space — known as proprioception — as well as what they’re holding. The central computer, meanwhile, is a Tesla-designed SoC with WiFi and LTE for permanent connection. The battery, too, is Tesla-developed, a 2.4 kWh battery pack that’s built into the chest of Optimus.
It’s expected to last for a full day’s work, though what exactly that will comprise is unclear at this stage. “There’s still a lot of work to improve Optimus,” Musk concedes, “and refine it.”
