Machine learning and computer vision technology have enabled rapid progress in the field of robotics. As a result, domestic robots have become smarter and more affordable, and are increasingly taking over mundane household tasks such as floor and window cleaning, pool cleaning, or lawn mowing. In the future, their use will extend into new areas including education, entertainment, and elderly assistance. II-VI offers laser light sources and optical components for range sensors and 3D cameras that enable navigation, object recognition, and obstacle avoidance in domestic robots.
