Programming TeleOp

Getting Started!

This year's Starter Bot program offers a slightly more technical solution than previous years. If your team is new to FTC, or in need of a review, we strongly recommend checking out our updated Hello Robot Programming Guide before diving in!

To begin, let's take a look at the configuration and actuators used in this year's design.

Configuration

Before getting started with programming we needed to create a configuration file. Below is an overview of how the robot is configured for the TeleOp code to function as expected:

Port Type	Port Number	Device Type	Name
Motor	0	REV Robotics Ultraplanetary HD Hex Motor	arm
Motor	1	REV Robotics Core Hex Motor	wrist
Motor	2	REV Robotics Ultraplanetary HD Hex Motor	leftDrive
Motor	3	REV Robotics Ultraplanetary HD Hex Motor	rightDrive
Servo	4	Servo	claw
Servo	5	Continuous Servo	intake

Configuration File Download

Right click the file below and select "save link as". To put this configuration file on your robot, drag this file into the "FIRST" folder of your Control Hub's file system.

Wiring Diagram

Wiring diagram for the 2024-25 Starter Bot

Device Name	Device Type	Port
arm	UltraPlanetary Gearbox Kit and HD Hex Motor	Motor/Encoder Port 0
wrist	Core Hex Motor	Motor/Encoder Port 1
leftDrive	UltraPlanetary Gearbox Kit and HD Hex Motor	Motor/Encoder Port 2
rightDrive	UltraPlanetary Gearbox Kit and HD Hex Motor	Motor/Encoder Port 3
claw	Smart Robot Servo	Servo Port 4
intake	Smart Robot Servo - set to continuous mode	Servo Port 5

The Smart Robot Servo can be changed to continuous mode using the SRS Programmer!

Gamepad Setup

The 2024-25 REV DUO FTC Starter Bot is designed to use a split arcade drive for the default. Check out our Upgrades page for the arcade drive version of the program.

In split arcade drive, the left joystick will control forward and reverse motion of the robot, and the right joystick will control turning. This is similar to how some RC cars are driven and video games are played.

Not all gamepads have buttons labeled the same way. Check the manufacturer's documentation for accurate button mapping.

2024-25 REV DUO FTC Starter Bot Gamepad Layout:

Gamepad Input	Function
Right Joystick	Turn left and right
Left Joystick	Drive forward and reverse
A/Cross	Intake Preset Position Arm down, wrist out
B/Circle	Wall Grab and Unhook Preset Position Arm up to grab, wrist in - first click Arm up to unhook, wrist in - second click
Y/Triangle	Hover High and Clip High Preset Position Arm up to low basket height, wrist in Arm lower to clip, wrist in
X/Square	Low Basket Preset Position Arm up to low basket height, wrist out
D-pad Up	Arm Up
D-pad Down	Arm Down
D-pad Left	Wrist Out
D-pad Right	Wrist In
Left Bumper	Reset arm/wrist to Initialization Position
Right Bumper	Claw toggle to open or close
Left Trigger	Reverse intake flaps
Right Trigger	Run intake flaps

More information on programming gamepads for use with your robot can be found at Hello Robot - Using Gamepads.

The REV USB PS4 Compatible Gamepad (REV-31-2983) has two remappable M-buttons on the back side of the controller. By default, these are mapped to circle and cross.

Please see the product page for directions on remapping these buttons.
