Wires and Stuff�Lesson 1

How does electricity work?

In simple terms, electricity is the the movement of electrons throughout the metal wires.

Wires

Throughout our subteam, we use a variety of wires that accomplish different things. The color and size of wires is very important and something that we need to pay attention to.

CAN wire

The CAN wire on our robot is the 20 gauge green and yellow wire.

It connects all of our

• Motors
• Encoders
• RoboRio
• Pigeon
• CANivore
• CANdle
• PDH/P

CAN high: Yellow CAN low: Green

The CAN wire is one big loop, and is often called a CAN loop or a Daisy Chain.

• Purpose is to easily communicate with all components at once.
• Crimped with Ferrule crimps

PWM wire

​

• The PWM Wire has usually 22 gauge red, black, and white wires that can be easily pulled apart, and often are.
• Typically crimped with PWM Males and Females or occasionally Ferrules

What do the colors mean in direct current?

Red- Positive (+)

Black- Negative (-)

White- Neutral, signal

Power wire

About power wires

• Power wires are usually 10, 12 or 14 gauge. We often use 12.
• Use anderson crimp
• The purpose of power wires is to connect DC components to power sources or other DC components

Battery wire

About battery wires

• Battery wires are usually 4 or 6 gauge
• They use a large special anderson crimp and have a specialized crimping system.
• They typically have a housing on the end that holds the red and black wire. This is connected to the battery
• Our batteries consist of wires that are screwed on. They have a specialized assembly. See picture below. Veteran members will teach assembly in build season.
