/ref> The essence of the design is represented in three categories; 200, 500, and 700 series. The 200 series is a smaller desktop unit. Notably, this model was used for the first robotic stereotactic brain biopsy in 1985. The 500 Series and can reach almost 2 meters up. This model is the more popular design and is the most recognizable configuration. The 700 series is the largest of the group and was intended for assembly line, paint, and welding work. All designs consist of two main components: the mechanical arm and the control system. These are typically interconnected by one or two large multi-conductor cables. When two cables are used, one carries power to the servo motors and brakes while the second carries the position feedback for each joint back to the control system. The control computer is based on the LSI-11 architecture which is very similar to PDP11 computers. The system has a boot program and basic debug tool loaded on ROM chips. The operating system is loaded from external storage through a serial port, usually from a floppy disk. The control unit also contains the servo power supply, analog and digital feedback processing boards, and servo drive system. The arm appears in the film Innerspace. An arm was displayed in the "Bird And The Robot" attraction at the
