A burger-flipping robot has been switched off after it failed to keep up with orders. The robot that started work this week in a California restaurant has been forced to take a break because it was too slow.

The robot was installed at a Cali Burger outlet in Pasadena and replaced human cooks. But after just one day at work the robot has been taken offline so it can be upgraded to work faster.

Its human helpers are also getting extra training to help the robot keep up with demand. The robot is believed to have been given time off because news about it spread widely, and led to more interest and orders than the restaurant could handle.

In a statement Miso Robotics, which made Flippy, said it was testing the code that controls the robot to ensure that it can cook quickly enough to fulfil orders at peak times. Prior to starting work, Flippy was said to be capable of cooking up to 2,000 burgers a day.
