Realistic physics via GPU-accelerated engines and RTX ray tracing. Multi-sensor simulation (RGB-D cameras, Lidar, Radar, IMU, contact sensors). Extensible via platform APIs and can integrate into custom USD-based simulators.

Isaac Lab is an open-source modular robotics learning framework built atop Isaac Sim. It simplifies research workflows across reinforcement learning, imitation learning, and motion planning by offering robust, GPU-accelerated simulation with realistic sensor and physics fidelity—ideal for sim-to-real robot training. Compatible and optimized for use with Isaac Sim versions (e.g., Sim 5.0 and 4.5). GPU-accelerated, high-fidelity physics and sensor simulation suitable for complex learning tasks. Offers a variety of robotic environment simulations on both Linux and Windows.

QVM is a quaternion, vector, and matrix class set in C++ for 3D kinematics.

Critterding is a "Petri dish" universe in 3D that demonstrates evolving artificial life. Critters start out with completely random brains and bodies, but will automatically start evolving into something with much better survival skills.

VirtualVEX is an open-source simulator platform for the VEX robotics design system. It features full competition simulation, with automatic scoring and timing and multiple robot designs to choose from. VirtualVEX is also programmable: users can write and upload code using the bundled VVDevelop IDE, which has one-click deployment and testing support. VirtualVEX also supports dual-pad joysticks similar to those used by the actual VEX platform, allowing users to get realistic driving practice. The software is free and is distributed under the GPL v.3

A Java client for the Player/Stage robot platform.

Aquila 2.0, an open-source cross-platform software architecture for cognitive robotics that makes use of independent heterogeneous CPU-GPU modules with loosely coupled dynamically generated graphical user interfaces.

FEMM procedures to analyse rotating machines.

A very simple java simulation of the human body to simulate a 3D drawing manikin,with plenty of freedom of movements of the limbs and rotation of the body to implements a 360 degrees view.Source code available.No openGL.Improvements to come !

The Mars Rover Simulator project is based on the evolutionary robotics paradigm where an artificial agent acquires its skills through the process of artificial evolution. This simulator can be useful to evolve neural network controllers for the rover

openSDK is a free and open-source implementation of Sony's OPEN-R Development Kit. OPEN-R is a trademark or a registered trademark of Sony Corporation.

- - - T H I S P R O J E C T M O V E D T O G I T H U B - - - A framework for the implementation of advanced real-time control systems which uses signal/block-based schematics (like Simulink) extended by several features like state machines and online-exchangeable sub-simulations. Besides, this framework properly handles multiple threads, their communication, allows to synchronise control systems to external events (e.g. variable timers or incoming network packages) and provides many other nice features. Because of a high-level schematic-description language -- in form of provided Scilab commands -- only a minimal implementation-effort (no error-prone C-programming) is required.

SB-MASE is aimed at students and researchers in AI, for simulation and control of agents and robots. It uses task based decomposition and the subsumption architecture as its core control mechanisms and includes numerous possibilities for adding plug-ins.
