Doug Field, the engineer who ran Tesla’s Model 3 program and later Ford’s entire EV operation, is now president of Mind Robotics, the industrial robotics startup Rivian CEO RJ Scaringe spun out of Rivian last year.

He lands at a company that has now raised more than $1 billion in under a year, and he’ll run product, engineering, and operations alongside Scaringe.

Tesla is now building several hundred Optimus humanoid robots per week at Fremont, roughly 10 times its Q2 output, according to a new report. But the robots coming off the line still can’t handle generalized tasks – limiting their usefulness.

The report also describes fragile hands, misaligned parts on the assembly line, and suppliers that can’t hold quality at volume. Those are the two problems that decide whether humanoid robots make money: generalization and reliability.
