dg3f_m_gz ROS 2 Package 🚀

📌 Overview

It provides detailed Gazebo simulations of the Delto Gripper-3F-M using ROS 2 control joint trajectory controllers.

📦 How to Install Dependencies for a Single ROS2 Package (dg3f_m_gz) Using rosdep

Follow these steps to install dependencies specifically for the dg3f_m_gz package only, excluding other packages in your workspace.

1️⃣ Navigate to the workspace root

cd ~/your_ws

2️⃣ Update rosdep (without sudo)

apt update
rosdep update

⚠️ Important: Do not use sudo when running rosdep update.

3️⃣ Install dependencies only for the specific package (dg3f_gz)

rosdep install --from-paths src/DELTO_M_ROS2/dg3f_m_gz --ignore-src -r -y

• --from-paths: Limits dependency checking to the specified path
• --ignore-src: Ignores packages already present in your workspace
• -r: Recursively checks dependencies within subdirectories
• -y: Automatically confirms installation of dependencies

✅ Verify Installation by Building the Package

After installing dependencies, confirm the package builds successfully:

colcon build --packages-select dg3f_gz

This command builds only the dg3f_m_gz package, ensuring it compiles correctly.

🎮 Simulation Usage

Below are detailed instructions for launching the Delto Gripper-3F simulation and executing control commands using ROS 2 Control.

🎛️ Controlling Left Delto Gripper-3F

1. Loading a URDF model into Gazebo

Launch the Left Delto Gripper-3F simulation with:

ros2 launch dg3f_m_gz dg3f_m_gz.launch.py

This command initializes Gazebo, loads the specified URDF robot description, and activates all necessary ROS 2 control plugins.

2. Sending control commands using ROS 2 Control

• Python Example: dg3f_m_left_gz_test.py

Run the Python test script:

ros2 run dg3f_m_gz dg3f_m_gz_test.py

• 💻 C++ Example: dg3f_m_left_gz_test.cpp

Execute the C++ test node:

ros2 run dg3f_m_gz dg3f_gz_test_cpp
