Efficient manufacturing calls for coordinated systems of shop personnel, equipment and software. These systems increasingly include robotic technology, as manufacturers recognize the reliability, repeatability and flexibility that robots provide. According to the International Federation of Robotics, the number of industrial robots in use worldwide will increase to around 2.6 million by 2019, about one million more than in 2015. Approximately 70% of industrial robots are used in the automotive, electrical/electronics and metal and machinery industries.
