The number of robots used in industrial applications continues to grow and their capabilities continue to evolve. The first stationary industrial robot, the Unimate, was installed in a factory by General Motors in 1961. According to the International Federation of Robotics (IFR), the World Robotics report released on Jan. 20, shows that more than 2.4 million industrial robots are currently operating in factories around the world. And this number is expected to grow dramatically in the coming years. Following the rapid adoption of stationary robots, the next development was the deployment of mobile robots in the form of automatic guided vehicles (AGVs).
