The robot helped test vision preservation technologies four times faster.

In Japan, the humanoid robot Maholo processed 200 million possible conditions through trial and error to grow retinal replacement layers from human stem cells to restore vision. He continuously repeated a series of precise movements and evaluated the results of his experiment, changing the conditions for the next - and so on thousands of times in a row. The main task of the robot was to select the optimal type, dose and duration of action of various reagents. In 185 days, he completed experiments that would have taken humans two and a half years to complete.
