What each one is
Diffusion Policy
Diffusion Policy generates robot actions with a diffusion model — the technique that made visuomotor imitation learning finally work reliably.
- State-of-the-art results on manipulation
- Reference implementation from the original paper
- Widely reused as a baseline
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
Diffusion Policy is imitation learning, while MoveIt 2 is motion planning. Their licenses differ (MIT vs BSD-3-Clause), which matters if you ship a commercial product. In short, Diffusion Policy fits cloning a demonstrated skill rather than engineering a controller, and MoveIt 2 fits making a robot arm reach for something without hitting anything.
Which should you choose?
Choose Diffusion Policy for cloning a demonstrated skill rather than engineering a controller. 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 Diffusion Policy or MoveIt 2 easier to use?
Both sit at a similar level (Advanced). Your choice should come down to fit rather than difficulty.
Are Diffusion Policy and MoveIt 2 free?
Diffusion Policy is free and open source (MIT), and MoveIt 2 is free and open source (BSD-3-Clause). Neither charges for the core software.
Can I run Diffusion Policy and MoveIt 2 locally?
Diffusion Policy: yes · MoveIt 2: yes. Both can be used without sending your data to a third-party cloud where their setup allows.
Diffusion Policy vs MoveIt 2 — which should I pick in 2026?
