Apparently, Tesla (NASDAQ:TSLA) CEO Elon Musk wasn’t always eager to put robots on the production floor. However, it seems that Musk is now ready to accept and even embrace the automation revolution. He’s even getting ready to unveil a robotics project with implications far beyond car manufacturing. It’s a risky proposition, to be sure, yet I am bullish on Tesla stock nonetheless.

Electric vehicle (EV) manufacturer Tesla is known for its controversy-courting chief executive as much as its sleek, powerful cars and trucks. Musk pioneered, or at least popularized, the vehicle electrification movement in America.

Now, however, he’s preparing to expand into a new but related business venture. Consequently, Tesla stock investors will need to be on board with Musk’s evolving vision of what EV production should look like – and who (or more accurately, what) will make the clean energy vehicles of today and tomorrow.

Tesla’s Investors Should Mark Their Calendars for September 30

Get ready, Tesla shareholders, as September 30 will be a day to remember. No, it’s not an earnings report or even a new vehicle release. It could actually be more impactful than any recent Tesla event, as “AI Day” just might unveil the future trajectory of the company, and of automation technology in general.

On that day, Tesla plans to reveal a prototype from the company’s project known as Optimus (presumably, a reference to the Transformers film series). Optimus is designed to be a labor-saving robot with applications in Tesla’s production factories, but also potentially in people’s homes someday.

In typical fashion, Musk teased the development of Optimus with a tweet, writing that Tesla’s “Autopilot/AI team” is working on the robotics project. This tweet, which hinted at an end-of-the-month deadline, garnered thousands of likes and hundreds of retweets. Moreover, Musk has been reported as stating that Optimus production could commence next year.
