The Electrical subdivision is an important aspect of creating a functioning robot and revolves around wiring up all of the sensors, motors, batteries and processing devices. In short if it uses electricity and resides on the robot it is Electrical's job to make sure it functions as intended.
Electricity as a concept is pretty simple. The flow of electrons through a conductor such as copper or silver wires. In the realm of electrical engineering there is always more one can learn, so for the purpose of this wiki I am only going to go into detail on how to Wire a FIRST robotics robot and get it into a functioning state.
