Easier to work with. Robotic automation is much easier to work with than humans. Robots don’t require coaching or ongoing training. Once one Robot is trained to do the work, all other robots immediately learn the same things. Robots don’t require the same supervision as humans and can work 24 hours a day, 7 days a week, without a break.
You see, there was an interesting article in Business Insider Tech News titled ”Foreign robotics companies find success in China,” written by Jonathan Camhi published on September 22, 2015 which stated:
Other robots use machine vision systems to perform complex tasks, such as weld inspection and optimization in the automotive industry. These usually involve elaborate actions and motion sequences, which the robot may even have to identify itself.
Pharmaceutical companies use machine vision systems in automated production lines to inspect injection needles, which are unusable if blunt or bent. Multiple cameras photograph needles as they flow through the system on powered conveyors. Sophisticated computer software analyses the captured images to determine needle sharpness and check the contour of the tube. Industrial robots use this information to separate and discard defect needles.
U.S. manufacturing is much more automated than it was thirty years ago. Automation equipment, such as welding robots, perform the manufacturing tasks. Human workers maintain and program the robots. This requires a lot of technical knowledge. The demand of robot programmers is high.
