    Joysticks

    The standard input device supported by the WPI Robotics Library is a USB joystick or gamepad. The Logitech Attack 3 joystick provided in the KOP from 2009-2012 comes equipped with eleven digital input buttons and three analog axes, and interfaces with the robot through the Joystick class. The Joystick class itself supports joysticks with more capabilities as well such as the Logitech Extreme 3D Pro included in the 2013 KOP which has 4 analog axes and 12 buttons. Note that the rest of this article exclusively uses the term joystick but can also be referring to a HID compliant USB gamepad.

  • Once commands are defined they can run in either the teleop or autonomous part of the program. In fact, the power of the command based programming approach is that you can reuse the same commands in either place. If the robot has a command that can shoot Frisbees during autonomous with camera aiming and accurate shooting, there is no reason not to use it to help the drivers during the teleop period of the game.

    Getting Started with the SmartDashboard

    The SmartDashboard typically runs on the Driver Station computer and will do two functions:

    1. View robot data that is displayed as program status as your program is running.
    2. View sensor data and operate actuators in Test mode for robot subsystems to verify correct operation.

    The switch between program status and test modes are done on the Driver Station.

    Configuring an Axis Camera

    Three different Axis camera models are supported by the FRC software, the Axis 206, Axis M1011 and Axis M1013. This document provides instructions on how to configure one of these cameras for FRC use. To follow the instructions in this document, you must have installed the NI 2015 FRC Update Suite and Configured your radio

    RoboRIO User Accounts and SSH

    Note: This document contains advanced topics not required for typical FRC programming

    The roboRIO image contains a number of accounts, this article will highlight the two used for FRC and provide some detail about their purpose. It will also describe how to connect to the roboRIO over SSH.

    Creating groups of commands

    Once you have created commands to operate the mechanisms in your robot, they can be grouped together to get more complex operations. These groupings of commands are called CommandGroups and are easily defined as shown in this article.
