Research Notes
A distinguishing strength is the breadth of programming interfaces: the same simulation can be driven from embedded scripts, compiled plugins, or remote clients across seven languages, with MATLAB and Octave supported alongside Python, Java, and C++. That lets research groups and industrial teams reuse controller code they already maintain instead of rewriting it for the simulator.
The simulator offers several interchangeable physics engines and exposes exact distance and collision queries, so a team can trade simulation speed against fidelity without changing its tooling. Compatibility with its V-REP predecessor means existing scenes and licences continue to work, and an education-only edition removes the cost barrier for university teaching.
The commercial editions and the geometric and kinematics plugins are priced through individual contact rather than published terms, which makes budget comparison difficult against simulators distributed at no licence cost. The free education edition is restricted to schools and universities and may not be used commercially, or by companies, research institutions, foundations, or other non-academic bodies.
Its rendering and sensor models are built for control and algorithm development rather than photorealistic or large-scale synthetic-data generation, where GPU-driven simulators are chosen instead. The core library is published under the GNU GPL while the shipped application is proprietary, so the open-source component and the commercial product carry different terms.
CoppeliaSim descends from the V-REP robot simulator and is maintained by Coppelia Robotics from Zurich. The company states that development of V-REP was discontinued in favour of the successor offering, and that CoppeliaSim is a fork of the V-REP project, fully compatible with it and faster, which it characterises for existing customers as a name change rather than a new product.
The holding company changed hands when Blue Workforce A/S merged with Coppelia Robotics in December 2016 and became sole shareholder, and Coppelia Robotics continued operating independently from Zurich after Blue Workforce filed for bankruptcy in April 2019. Development has since been published through the vendor's own release blog and changelog, alongside a public code organisation hosting the core library, manual, and default models.
CoppeliaSim is a multi-platform desktop robotics simulator in which a scene is composed from objects and models that are each controlled independently through a distributed control architecture. Individual objects accept control from an embedded Python or Lua script, a C or C++ plugin, a remote API client in Python, Lua, Java, MATLAB, Octave, C, C++, or Rust, or a custom solution.
Simulation is driven by a choice of five physics engines and supports forward and inverse kinematics, volumetric proximity and vision sensors, collision and exact minimum-distance calculation, and path and motion planning through the OMPL library. It is applied to algorithm prototyping, industrial and factory automation simulations, robotics education, remote monitoring, safety verification, and digital twin work, and ships in Lite, Pro, and education-only editions.
