What physics simulators exist which are open source/free? AI Gym uses a proprietary for-cost physics engine making it nonviable.

  • $\begingroup$ -Gazebo is hard to use. I don't know anything about webots which was the only other one. But it looks borderline properitery also. The MS robotics studio idk if it is still active or not. $\endgroup$ Mar 20 '20 at 21:11
  • $\begingroup$ Welcome to Robotics FourierFlux, but I'm afraid that shopping questions really aren't a good fit for a stack exchange site. We prefer practical, answerable questions based on actual problems that you face. Take a look at How to Ask and tour for more information on how stack exchange works, and the Robotics question checklist for details of how to write a good question. $\endgroup$

As for as I am understanding your question, you are asking about open source physics engines for simulation, So here's a short list:
1. Box2D,
2. Bullet Physics,
3. Chipmunk,
4. Chrono::Engine,
5. DynaMo,
6. Moby (Physsim),
7. Newton Game Dynamics,
8. Open Dynamics Engine,
9. Open Physics Abstraction Layer,
10. OpenTissue.

  • $\begingroup$ Thanks, I tried pybullet but there aren't any sensors actually built into it, that's probably the same with the other ones also. Not sure why Ben has an issue with this since simulators are a core part of robotics. $\endgroup$ Apr 1 '20 at 14:46
