Scientists recreate eye with camera

Using a camera and a muscle-based propulsion system, Georgia Tech scientists have succeeded in simulating eye movements. The technology can be used for robots and eye examinations.

According to the scientists, materials with piezoelectric properties are used to control the camera, which is designed to mimic an eye. The piezoelectric effect generates movement with electricity. The required actuators, the parts that generate movement, are based on the functioning of muscles, which means that the control of robot eyes can be improved. The actuators, which are connected in series or parallel with each other, have a structure that is comparable to the cellular structure in muscles.

By imitating muscles, the researchers ensure that different actuators that drive the movement can work together. The actuation of several actuators can therefore ensure that they reinforce each other’s movement, just as is the case with muscle bundles. Previously, it was not possible to generate sufficient movement with piezoelectric actuators, the scientists say.

Robots can be improved with the drive system for the camera. For example, robots with improved ‘vision’ can be used for operations in hospitals. Scientists can also study eye movements with the system.
