Tesla's Robotic Revolution: Optimus Hand Takes a Giant Leap with 22 Degrees of Freedom
1min read Tesla's recent progress in humanoid robotics has taken a significant leap forward with the introduction of its latest Optimus robot, which now boasts a sophisticated hand featuring 22 degrees of freedom. This development marks a milestone in the realm of robotic dexterity, as the human hand is typically associated with 27 degrees of freedom. This advancement allows the robot to perform more intricate and precise tasks, highlighting Tesla's continuous innovation in robotics.
On November 28, Tesla's official robotics account unveiled a new demonstration video where the Optimus robot effortlessly caught a tennis ball and set it down, showcasing its dexterous fingers that can bend with relative ease. Milan Kovac, an engineer on the Optimus team, described this enhanced hand as a "milestone achievement," doubling the degree of freedom from its predecessor.
This latest model integrates a vastly expanded tactile sensory integration, enabling more nuanced control via tendons. While all drive units have been moved to the forearm, thereby increasing its weight, the team is actively exploring ways to reduce it. A fascinating challenge is equipping the fingers and palm with a protective layer that retains softness without compromising sensory perception.
The previous generation of the Optimus robot had a hand equipped with 11 degrees of freedom, focusing primarily on forearm flexibility, enabling it to perform tasks such as folding clothes and sorting objects. Now, the 22-degrees-of-freedom hand allows for even more complex movements, potentially even playing musical instruments, as Elon Musk suggested during his comments at Tesla's stakeholder meetings.
At Tesla's October "werobot" event, the new dexterous hand made its debut, displaying both new motion capabilities and an exoskeleton featuring external actuators housed in the forearm, alongside a wrist with increased mobility. This design aligns with expectations around Tesla's use of hollow cup and screw drive mechanisms that mimic human-like joint structures.
The evolution of the dexterous hand as a core component in humanoid robots has seen notable manufacturers like Tesla and other innovators actively developing proprietary solutions. As robotics advances, industries are seeing rapid enhancement in hand freedom, steering towards higher integration and smart features. Meanwhile, new patents and prototypes unveiled in the market consistently push the limits of what robotic hands can achieve, both in performance and cost efficiency.
Tesla’s latest advances in its Optimus robot hand not only enhance its functional capabilities but signal the potential for exponential growth in the related industrial sectors. These enhancements create significant opportunities for industries involved in motor, transmission, and sensor technology development. As the market adapts to these innovations, companies across the robotics supply chain are poised for substantial growth, driven by Tesla's technological breakthroughs.
