The primary purpose of a robot is to perform repetitive and / or precise tasks. Robots can also perform tasks in work environments that are too dangerous for humans. Robots can perform automatic tasks, but some are also endowed with a certain intelligence. Their adaptability requires qualities of perception in order to interact with their environment. Robots are generally present in different fields of application such as the manipulation of objects, welding, assembly of parts in the automotive industry, for example. Robots are therefore used in factories but also in pharmaceutical laboratories and hospitals. However, it should be noted that the automotive industry uses more than 50% of all industrial robots.
