The robot is now able to move more confidently than before. It can now climb stairs, find and connect to charging stations on its own, and navigate unfamiliar spaces autonomously, relying only on information from its built-in cameras. While walking, Optimus can hold a weight of 11 kilograms in its hands. At the same time, its actuators do not overheat. When the battery is low, the robot is now able to find and connect to charging stations on its own without assistance. The connector is located on its back, the robot docks with the charger using the rear-mounted cameras, and after recharging, it returns to work on its own. Another major update is that Optimus has started learning how to interact with humans. Its neural network, for example, has been trained to hand people snacks and drinks lying on the table via gesture commands and voice requests. All of the algorithms Optimus uses to manipulate objects, detect obstacles, localize and navigate are run directly on the FSD's embedded computer, the same one used in the company's cars. The engineering team is currently working on training the Optimus robot to walk on uneven terrain. Judging by the published footage, it can already climb stairs.
