RoboSchool

Open source software for robot simulation, integrated with OpenAI Gym

Roboschool is a set of open source robot simulation environments for reinforcement learning, created as an alternative to the Mujoco physics engine. It integrates with OpenAI Gym and provides a variety of continuous control tasks, including humanoid locomotion, quadrupeds, and robotic arms. The library is built on the Bullet Physics engine, making it accessible without the licensing requirements of Mujoco. Roboschool includes training scripts and examples for applying reinforcement learning algorithms to its environments. While the project has since been deprecated in favor of more modern frameworks, it remains historically significant as a bridge between early reinforcement learning research and scalable, open-access environments. Its goal was to make reproducible robot learning experiments available to a wider audience without restrictive dependencies .

OpenLoco

An open source re-implementation of Chris Sawyer's Locomotion

An open source re-implementation of Chris Sawyer's Locomotion. A construction and management simulation video game that simulates running a transport company. OpenLoco is an open-source re-implementation of Chris Sawyer's Locomotion (CSL), the spiritual successor to Transport Tycoon. OpenLoco aims to improve the game similar to how OpenTTD improved Transport Tycoon, and OpenRCT2 improved RollerCoaster Tycoon. CSL was originally written in x86 assembly, building on top of the RollerCoaster Tycoon 2 engine. However, the engine has changed substantially enough that OpenLoco currently does not share its codebase with OpenRCT2. The reimplementation efforts of OpenLoco are gradual, aiming to ultimately rewrite the entire game in C++. In the earlier years of the project, the in-game UI has been completely reimplemented, and most of the underlying data and object structures have been uncovered. Recent efforts have focussed on reimplementing the game (command) logic.
