Robo-chefs have shown off their cooking skills at the International Food Machinery and Technology Expo in Tokyo.

The robots included one that made Japanese pancakes and another which served sushi with a life-like arm.

There was also a robot which came in the form of a table on wheels and served drinks and food, and another which chopped vegetables at great speed.

Most of the robots on display at the expo were for demonstration only and not yet for sale.
