Asia Tech Wire (Nov 11) -- Tesla is improving the design of its Optimus robot so that it can be mass-produced, Tesla CEO Elon Musk revealed in a post.

Musk also said that Optimus is already performing a number of tasks in the factory and that the scope of its ability is expanding rapidly.

"The toughest part by far is improving the design of Optimus for ease of manufacturing and tooling up a complex supply chain, so it can be made in significant numbers," he added.

At last month's "We, Robot" event in Los Angeles, Musk said the robot would sell for between $20,000 and $30,000, and would essentially serve as the perfect assistant for anyone who needs help.
