What each one is
Gymnasium
Gymnasium is the maintained successor to OpenAI Gym: one API that every RL algorithm and environment speaks.
- The interface the whole RL ecosystem implements
- Dozens of environments included
- Actively maintained, unlike the original Gym
MoveIt 2
MoveIt is the reference stack for planning collision-free arm trajectories, grasping and kinematics on top of ROS 2.
- Battle-tested motion planning
- Deep ROS 2 integration
- Supports most commercial arms out of the box
Key differences
Gymnasium is rL environment API, while MoveIt 2 is motion planning. Their licenses differ (MIT vs BSD-3-Clause), which matters if you ship a commercial product. Gymnasium leans more beginner-friendly, whereas MoveIt 2 is more suited to advanced users. In short, Gymnasium fits learning RL, or benchmarking an algorithm against a known baseline, and MoveIt 2 fits making a robot arm reach for something without hitting anything.
Which should you choose?
Choose Gymnasium for learning RL, or benchmarking an algorithm against a known baseline. Choose MoveIt 2 for making a robot arm reach for something without hitting anything.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
Frequently asked questions
Is Gymnasium or MoveIt 2 easier to use?
Gymnasium is generally the easier of the two to get started with, while MoveIt 2 rewards more setup with more control.
Are Gymnasium and MoveIt 2 free?
