Robotics technicians: [R.sub.x] for robots; the use of robots has opened the door for new career opportunities in the field of robotics and automated

Robots have intrigued humans for years. They have been portrayed in science fiction books and movies as lifelike, ready and willing to do their human master's bidding. In reality, robots don't typically look like R2-D2 or C-3P0 from Star Wars. They look more like large metal arms and hands.

The Robotic Industries Association (RIA) defines a robot as "a reprogrammable, multifunction manipulator, designed to move materials, parts, tools, or special devices through variable programmable motions for the performance of a variety of tasks."

Most robots are used in manufacturing plants, where they perform welding, painting, drilling, cutting, and material-handling tasks. They are controlled by a computer, not a human, and can be reprogrammed to perform different tasks as needed.

From Bolts to Computers

Robotics technicians are the people who install, repair, and maintain robots. These technicians use hand and power tools, testing instruments, manuals, schematic diagrams, and blueprints to perform their job duties.

"One minute they'll have a wrench in their hand, and the next minute they'll be fixing the program that moves the robot," says Jeff Chapman, president of The Chapman Group, an Arizona employment search company. Chapman has been involved in manufacturing automation technology for 20 years.

According to Chapman, technicians must be able to work with electromechanical systems. This means they must have knowledge of electronics (controls, computer monitoring, sensors), mechanics (movement of mechanical parts), and computer technology (systems programs).

Robotics technicians must possess a broad base of knowledge. "It is very involved; it's more than just programming," says Chapman.

Prior to installing a robot, a technician ensures that the site is ready for installation. Electrical wires, switches, and circuit breakers must be available and ready to go. Then the technician uses tools and equipment, sometimes even a crane for large robots, to position and then bolt the robot in place.

All robotics technicians must be able to communicate with robotics engineers, the people who design and develop new robots. Those technicians who closely assist the engineer with the design and development are sometimes referred to as robotic design technicians.
