joystick_controller Package

The Joystick Control Package is a ROS package developed specifically for ROS Noetic. This package provides a convenient way to interface with a joystick input device and use its positional information for controlling robots or other ROS-enabled systems.

Features

• Read the joystick position (X and Y coordinates).
• increase & decrease the robot's velocity (linear and angular).
• Support for different joystick types (analog, digital).
• Publish the joystick position as ROS messages.
• Easy integration with ROS Noetic.
• Customizable settings and configurations.

Nodes

   • ~angular_speed_decrease_index (default: "2")

Installation

To use the ROS Joystick Control Package, follow these steps:

1. Create a ROS workspace (if you don't have one already):

   mkdir -p ~/catkin_ws/src
   cd ~/catkin_ws/
   catkin_make
   

2. Clone the repository into your ROS workspace's src directory:

   cd ~/catkin_ws/src
   git clone https://github.com/KroNton/joystick_control.git
   

3. Install any necessary dependencies using ROS package manager:

   cd ~/catkin_ws/
   rosdep install --from-paths src --ignore-src -r -y
   

4. Build the ROS package:

   cd ~/catkin_ws/
   catkin_make

Usage

Launching Joystick Node

To launch the joystick node and start reading joystick data, use the following command:

roslaunch joystick_control joystick_control.launch

This will start the joystick node, which reads the joystick position and publishes it as Twist message.
