What are the features of Tesla's humanoid robot Optimus?

Elon Musk-led Tesla's Optimus Gen 2 robot was unveiled in December last year. The robot, which is still in the lab, features human body-like geometry. A video released earlier showed the humanoid robot doing squats, holding delicate objects like eggs without breaking them and more. Recently, Musk said it would be ready for sale by the end of next year.
