Tesla showcased Optimus' dance moves in two demonstrations this week, with the second demo surprising many.
Optimus' initial demo featured rhythmic actions trained in simulation, with a safety cable attached at the back for falls.
A follow-up demo showed Optimus performing ballet and modern dance moves untethered, as Elon Musk hinted at perfecting ballet movements.
Tesla VP Milan Kovac shared insights that the movements in the second demo were in real-time, fully learned in simulation, and required significant robot model improvements.
