| OUR TAKE | The first full-size humanoid built to be looked at rather than put to work. Fabric-wrapped, 27 degrees of freedom, and a motion stack that does runway walks and full splits. It will not do a single chore. | The volume play. Tesla is converting car production lines to build it - if any robot hits mass-market pricing first, it's this one. |
