The firm has an automated warehouse in Andover, Hampshire, where robots select crates containing specific items that make up customer orders.

They are currently brought over to a human team for selection but, in future, the hand could replace them.

Also in development is a humanoid maintenance robot called SecondHands.

It will work alongside a human colleague to maintain the warehouse.

The fruit and vegetable picker is part of a five-year research EU-funded collaboration between five European universities and Disney called Soma (Soft Manipulation), said Ocado spokesman Alexandru Voica.

The demonstration device is an early prototype, he said.

"People have tried suction cups, robot hands with three fingers... What we are trying to do is to actually mimic the human hand.

"The gripper is based on air pressure, which controls the movement of the robotic fingers.

"What we are trying to do is combine computer vision - being able to recognise products by looking at them - with the control aspect which is the gripping aspect."
