In the ever-evolving world of robotics, simulation serves as the backbone for testing and perfecting robotic behaviors without the risk of damaging actual hardware. The Spot Mini Mini OpenAI Gym Environment provides a robust platform for simulating quadruped robot movements using reinforcement learning. This blog will guide you through the essential steps to set up and run this environment effectively.

Motivation

The Spot Mini Mini environment was born out of the necessity for flexible and accessible simulation tools for the Spot Micro community. By using PyBullet, this simulator allows you to experiment with algorithms and control tactics without the threat of damaging physical robots.

Understanding the Code: An Analogy

Think of the Spot Mini Mini OpenAI Gym Environment as a virtual training ground for your robot, much like a sports training facility for athletes. Just as athletes practice different techniques in a safe environment to enhance their performance in real competitions, the Spot Mini Mini environment allows you to simulate various challenges and refine the robot’s movements without the risk of injury or failure. The core concept revolves around teaching the robot to navigate using defined gait patterns, like a dancer perfecting their routine.

How To Run

• Dependencies:
  • ROS Melodic
  • Gazebo
  • Pytorch
  • Pybullet
  • Gym
  • OpenCV
  • Scipy
  • Numpy
• Joystick Control with ROS:

  If you have a joystick, you’ll first need to set it up:

  • Get Number (you will see something like jsX): ls /dev/input*
  • Make it available to ROS: sudo chmod a+rw /dev/input/jsX
  • Ensure param name=dev type=string value=/dev/input/jsX matches your setup in the launch file.
• Non-Joystick Testing Environment:

  If you don’t have a joystick, simply navigate to spot_bullet/src and run .env_tester.py. This opens a PyBullet simulation with controls using scrollbars.

Troubleshooting Ideas

While everything is designed to run smoothly, you may encounter some hiccups along the way:

• If you’re having trouble with joystick connectivity, ensure that the device permissions are set correctly and match what your launch file is configured for.
• If the simulation crashes, check to see that all dependencies are installed and compatible with your version of Python and ROS.
• Be sure to check the console for error messages, as they typically provide guidance on what went wrong.
