Former SpaceX engineer says his pizza-making robot, located across the road from Elon Musk's HQ, sprayed cheese everywhere during testing

• Ex-SpaceX engineer said his pizza-making robot sprayed cheese everywhere during initial testing.

• CEO Benson Tsai, who worked at SpaceX for five years, said there was a bug in the robot's system.

• Stellar Pizza, which launches this spring, is just across the street from SpaceX HQ in California.

A former SpaceX engineer said his new robot that makes a pizza every 45 seconds, sprayed cheese everywhere when it was first built.

Benson Tsai, who worked at Elon Musk's space company for five years, said in an interview with Insider that he faced a number of failures while launching his culinary startup, Stellar Pizza, with two other ex-SpaceX engineers.

One of the failures happened three years ago when the pizza-making robot "dumped melted cheese everywhere" during testing, Tsai said.

Stellar Pizza's robot was attempting to make a cheese pizza, but the robot's motors started spinning the wrong way, pulled the cheese off the pizza and onto the automated peel, which slides the pizza in and out of the machine.

The cheese went in all the wrong places, according to Tsai.
