Parts of a Control System

The parts of a control system are the components necessary for the control system to be of any use. They provide greater functionality and an increased ability to create complex machinery. These elements are included in the kit of parts.

Robot Control System pieces

Robot Controller, controls the flow of information and processes said information based on what is programmed
12V battery, provides the power for the robot
7.2V backup battery, provides backup power (and is necessary for the servos to work)
RS 422 radio (RC), allows for wireless communication between the RC and the OI (not needed if system is tethered)
DB9 M-F cable (radio), standard 9 pin connector, connects the radio to the RC (not needed if system is tethered)
PWM outputs, allows direct control of servos and indirect control of motors through speed controllers
DB9 M-F cable (tether), standard 9 pin connector, connects the tether ports of the RC and the OI

Operator Control System pieces

Operator Interface, collects input controlled by human operator and sends it to the RC
AC adapter, lets OI run from a wall outlet (not needed if system is tethered or powered from competition port)
RS-422 radio (OI), allows for wireless communication between the OI and the RC (not needed if system is tethered)
DB9 M-F cable (radio), standard 9 pin connector, connects the radio to the OI (not needed if system is tethered)
Joystick, provides analog input to the OI from the human operator
