A team of scientists invested a great amount of work in developing a soft-robot ray that mimics the movements of its role model.
The small stingray consists of a gold skeleton and heart cells. These cells were manipulated so they would react to light. The cells were than grown in a zigzag pattern around the metal skeleton. Two sheets of silicone shaped this pattern.
Kedi Xu, a neural engineer at Zhejiang University in Hangzhou, Chine:
“One can imagine that one day we can use this technology to rebuild parts of the human body.”
The design of the artificial soft-robot:
When lit the heart muscles move like a real stingray would move. The researchers were able to move the stingray through a underwater parkour.
