Tesla may be putting a pause on the production of its humanoid robot, Optimus, due to major technical difficulties, according to a recent report by TrendForce, a well-known market research firm focusing on tech industry trends.
Citing sources from within China’s supply chain, TrendForce says Tesla is currently dealing with two big challenges: short battery life and problems integrating hardware and software effectively. While advancements in AI could help improve motion planning and energy efficiency, core issues—especially in the hardware—are slowing progress.
One major concern is the low efficiency of crucial parts like joint motors and transmission systems. These components are essential for the robot’s basic movements, and Tesla has reportedly not yet reached the necessary performance benchmarks.
Another major issue lies in Optimus’ dexterous robotic hand. Reports indicate that it has trouble handling weight and requires highly precise mechanical design, miniature actuators, and AI-based control systems. On top of that, simulating human-like behavior adds further complexity, meaning Tesla will likely need much more time to refine the design.
TrendForce also mentioned in its April 2025 report that many top robotics companies have revealed plans to begin mass production of humanoid robots in 2025 and 2026. However, it warned that missing key mid-year deadlines for locking in product specifications could lead to delays in those production schedules.
Tesla has not officially confirmed a pause in production, but the recent supply chain reports suggest the company may shift its timeline due to these unresolved technical issues.
