Tesla's Optimus humanoid robot demonstrated a new milestone by jogging across a lab floor in a video shared on December 2, 2025. The footage highlights improved mobility with natural form, as progress accelerates toward mass production. CEO Elon Musk envisions the robot transforming labor by handling monotonous tasks and potentially making work optional within 20 years.
On December 2, 2025, the official Tesla Optimus account released a video showcasing the humanoid robot taking a light jog in the lab, described as setting a new personal record with notably natural movement. This demonstration marks the latest advancement in Optimus's mobility, building on prior progress in walking and other motions.
The robot's appearance at the Neural Information Processing Systems (NeurIPS) Conference around the same time drew attention, with attendees sharing videos of its charging rig, overall movements, and particularly its hand capabilities. However, developing a dexterous hand remains a significant challenge for the third-generation Optimus. During Tesla's Q3 Earnings Call, Elon Musk emphasized the complexity: “I don’t want to downplay the difficulty, but it’s an incredibly difficult thing, especially to create a hand that is as dexterous and capable as the human hand, which is incredible. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason.”
Tesla continues developing Optimus through its Artificial Intelligence and Robotics teams, aiming for initial mass production stages where units will be sold and shipped to customers in the coming years. Musk has positioned Optimus as potentially the biggest product in history, capable of eliminating monotonous tasks such as cleaning, mowing the lawn, and folding laundry. In late November 2025, he predicted that AI and robotics advancements could make working optional in less than 20 years, echoing sentiments from Tesla's 2025 Annual Shareholder Meeting where he suggested Optimus could eliminate poverty and provide advanced medical care globally.
While mobility has advanced considerably, the functional hand is crucial for broader utility, underscoring ongoing engineering hurdles.
