Tesla's main announcement coming from the company's recent "We, Robot" event was the Robotax i (or the CyberCab, we're still not sure about the name). But perhaps the biggest impression was made by Tesla's updated Optimus robots, which freely walked among the crowd, talked to guests, served drinks, played games, and danced.

On Thursday, October 10 Tesla hosted their much anticipated We, Robot event where they unveiled their robotaxi.

Tesla stock vacillated Monday as investors continued to digest what they learned from the company’s Robotaxi Day held Thursday evening. Shares of the electric-vehicle maker opened $220.13, up 1.1%, then slipped to trade as low as $213.
