Bots2D

Background

While building my sumobot I found myself wanting to simulate my driving strategy. My sumobot is simple, so I didn't need a fancy 3D-simulator, and I went looking for a 2D-simulator instead. To my surprise, I couldn't find an obvious candidate, so I decided to build my own.

Features

My initial plan was to build a 2D-simulator only for simulating sumobots, but I ended up creating a more general 2D simulation framework featuring:

• Open-source (MIT license)
• C++
• Linux and Windows support
• Physics based on Box2D
  • Top-view and side-view
• Lightweight rendering using OpenGL, GLFW, GLAD and ImGui
  • Basic shapes, Texture, Sprite animation
• Robotics assets
  • Complete robots (sumobot and line-follower)
  • Sensors (range sensor, line detector)
  • Actuators (DC-motor)
  • Playgrounds (Sumobot dohyo, Line follower path)
  • Isolated controller code (easy to transfer to a real MCU)
  • It's easy to add new assets...

You can read more about the project in my lengthy blog post.
