General Overview
This repository provides a comprehensive introduction on how to simulate a 6DoF Robotic Arm from scratch using GAZEBO and ROS2. Additionally, it features a custom Reinforcement Learning Environment where you can test the Robotic Arm with your Reinforcement Learning (RL) algorithms. The goal is to facilitate the simulation and environment testing with a reacher target task, utilizing both RL and the 6DoF Robotic Arm to reach a visual target point.
Prerequisites
Before diving into the simulation, ensure you have the following prerequisites installed:

Understanding the Simulation: An Analogy
Imagine constructing a sophisticated robot arm, akin to how a sculptor molds clay into a masterpiece. Each line of code serves as a tool in the artist’s hands, shaping the robotic arm just as a chisel defines details in the clay. When you set up the robotic arm in Gazebo, visualize it as setting up an arena for a gymnastics competition—the stage is set, the audience (simulating environment) is excited, and the performer (robotic arm) is ready to showcase its magnificent moves. Through Reinforcement Learning, the arm learns to optimize its movements as a gymnast perfects their routine, performing better with every attempt at reaching its target.
Troubleshooting Ideas
If you encounter any issues during simulation, here are some troubleshooting tips:
- Make sure all prerequisites are correctly installed.
- Check compatibility between ROS2 versions and Gazebo.
- Ensure that custom configurations for the arm are set up correctly in the environment files.
- Monitor the terminal for error messages and documentation in the repositories used.
