Tesla CEO Elon Musk said on Thursday that the electric car manufacturer may launch a prototype of the “Tesla Robot” humanoid robot next year, designed for dangerous, repetitive or boring work that people don’t like to do. And design.

At Tesla’s Artificial Intelligence Day event, the billionaire entrepreneur stated that the robot is about 5 feet 8 inches tall and can handle tasks ranging from bolting a car to a car with a wrench or picking up groceries in a store.

Musk said in addressing labor shortages that robots will “have a profound impact on the economy.” He said that it is important to keep machines from being “super expensive”.

The Artificial Intelligence Day event comes at a time when the safety and capabilities of Tesla’s “fully autonomous driving” advanced driver assistance system are under increasing scrutiny.

Musk did not comment on the review of the safety of Tesla’s technology, but said he is confident of achieving fully automated driving, which is safer than humans who use current on-board cameras and computers.

Earlier this week, the US safety regulator launched an investigation into Tesla’s driver assistance system because the Tesla car crashed into a stationary police car and fire truck.

The two U.S. senators also called on the Federal Trade Commission to investigate Tesla’s claims about its “self-driving” system.

At Thursday’s event, Tesla also introduced a chip designed inside its high-speed computer Dojo to help develop its autonomous driving system. Musk said that Dojo will be put into operation next year.

He said that Tesla will also introduce new hardware to the autonomous driving computer of its Cybertruck electric pickup truck in “about a year or so.”

Tesla postponed the launch of this year’s highly anticipated Cybertruck in July, but did not give a time to market.

On Thursday, some people questioned Musk, who often touts technological advances in exhibitions, but then scaled back his plan, whether he can achieve his goals for robots.

“Is’Tesla Bot’ the next dream to drive the hype machine?” said Raj Rajkumar, a professor of electrical and computer engineering at Carnegie Mellon University.

“I can say with certainty that it will take more than 10 years for a humanoid robot from any company on the planet to go to the store to buy groceries for you.”
