A Harvard University professor, Kevin Kit Parker,  has produced a robotic stingray.

The robot is made of an elastomer body, a gold skeleton and a muscle layer made from artificial rat heart cells.

The rat heart cells have been genetically engineered to react to light.

The robotic stingray swims in a mixture of glucose, warm water and salt.  This mixture provides the cells with energy.

Artificial creations like this could help pave the best way to create a human heart.
