Tesla’s effort to scale production of its Optimus humanoid robot is running well behind schedule, with output so far this year measured in the hundreds of units, The Information reported, citing people familiar with the program. The figure leaves the company far short of Chief Executive Officer Elon Musk’s publicly stated goal of building about 5,000 robots in 2025. Engineers have struggled to fabricate the robot’s hands, leaving some completed units without operable forearms, according to the report. The bottleneck has slowed broader assembly inside a project that Tesla has kept largely under wraps. Musk has recently urged shareholders to look beyond electric vehicles and focus on a “future filled with robots,” positioning Optimus as a key driver of the company’s long-term growth. The production shortfall underscores the technical hurdles Tesla must clear before deploying the machines at scale in its factories or offering them commercially.
