Brax is a fast and fully differentiable physics engine for large-scale rigid body simulations, built on JAX. It is designed for research in reinforcement learning and robotics, enabling efficient simulations and gradient-based optimization.
Open source 3D physics and dynamics engine and library written in pure Java. This is a Java port of ODE / OpenDE (Open Dynamics Engine).
THIS PROJECT HAS BEEN MOVED TO A NEW LOCATION: http://www.ode4j.org
A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.
DVC2D is a physical simulation library capable of simulating and animating planar systems of rigid bodies experiencing intermittent and steady unilateral contacts with friction. One can also include friction between the bodies and the plane of motio
Yaobi is a fast collision detection library for general triangulated objects. It uses a hierarchical representation based on oriented bounding boxes. Yaobi compares well with other libraries when it comes to speed and memory consumption.
OpenSim - Open Simulator. Primarily a 3D simulator for multiple indoor and outdoor mobile robots. Includes 3D real-time rendering (via OSG) and a physics engine (via ODE). Current emphasis is on manipulators.
The mechSym toolkit is a set of classes that support
modelling classical mechanics systems with particular interset in robotic designs.
Classes simulate sensors, motors, mechanical linkages, and power.
visual time-elapsed simulations provided.
