1.1.2 - Bot Basics

Objective: Finish FIRST Module 2, then name the parts on a Team 2064 robot and say how power gets from the battery to a wheel.

Do this first

Module 2 is the required training for this page. It is about two hours. Open it, finish it, then come back here. A Dashboard login stores the credit. A school Google account does not.

Open Module 2: How Robots Work

When you return, you should be able to point at the main breaker, PDH, roboRIO, and radio and say what each one does. Tell a mentor the module is finished.

Check these parts

Mechanisms change every game. These do not. Use them to review what Module 2 covered.

Frame and drivetrain

The skeleton and the wheels. Tank runs each side together. Swerve steers each corner. If this fails, nothing else matters.

Battery

One 12-volt sealed lead-acid pack. Anderson SB50. No second pack in a match.

Main breaker

The big red 120 A switch. Robot on and off, and the last over-current stop.

PDH

Splits battery power into channels. Each channel has its own breaker or fuse.

Motor controller, then motor

A motor never wires straight to the PDH. The controller takes a command and switches battery power to the motor.

roboRIO

Runs the code and sends commands. It does not power the drive motors.

Radio

Links the robot to the driver station and the field. No link, no teleop.

CAN bus

Yellow and green wires between the roboRIO, the PDH, and the controllers. A bad wire can look like a dead motor.

Driver station

Not on the robot. Laptop, FRC Driver Station, controllers, and an Ethernet cable.

Bumpers

Required contact zone, team number, and frame protection.
