Tech billionaire Elon Musk has presented the latest prototype of a humanoid robot being developed by his Tesla electric car company.
Optimus appeared on stage at a Silicon Valley event, where it waved to the audience and raised its knees.
The CEO said the robot was work-in-progress but could be on sale to the public in a few years’ time.
Tesla’s mass-market robots will be tested by working jobs in the car factories, company engineers say.
The prototype was wheeled on stage during an annual Tesla AI [artificial intelligence] Day presentation.
People were shown a video of Optimus performing simple tasks, such as watering plants, carrying boxes and lifting metal bars.
The Tesla boss spoke of “a future of abundance” ahead.
“It really is a fundamental transformation of civilization as we know it,” he continued.
