Optimus, Elon Musk’s humanoid robot, has been delayed. Tesla told suppliers in mid-June to halt orders for at least two months while Optimus’ design is adjusted to cope with problems and new suppliers may be found . Problems are said to be limited battery life, overheating joint motors, low load capacity in Optimus’ hands and short transmission lifespan. Optimus’ hand movements currently have 22 degrees of freedom and this might need to be reduced. The original head of the Optimus program, Milan Kovac, left Tesla last month and Ashok Elluswamy, Tesla’s AI software VP, took over. The original plan was for 5k units in 2025 and 50k in 2026 and these targets may not now be met. Recommended Articles
