Robotics in Canada

Robotics is the branch of engineering that concerns robots: reprogrammable, multifunction manipulators designed to move objects and complete tasks through a variety of programmed motions. The field includes the conception, design, manufacture and operation of such machines. Robotics overlaps with a variety of other electronic and engineering disciplines including artificial intelligence (AI), bioengineering, computer science, mechatronics (the engineering of both electrical and mechanical systems) and nanotechnology. In the late 20th century, Canada distinguished itself in the field with the development of the Canadarm for space missions. Despite the challenges of competing in the international market, Canadian companies, institutes and researchers are now world leaders in the development of AI applications for robotics.
