Where does this market start and stop?
Industrial robotics overlaps with warehouse robots, cobots and plain factory machines, so we start by drawing a clear line.
A welding arm on a car line is in. So is a cobot that loads parts into a machine, and the software that plans its moves. A machine tool that only runs a fixed program is out, and so are robots built for homes or operating rooms.
That way, the size we give and every company we compare refer to the same market.
