What changed
A robot can look perfect in simulation while its virtual fingers quietly pass through an object.
Google DeepMind released MuJoCo 3.14 on September 22, 2026.
How it works
The release notes add an experimental IPC contact mode to the discrete integrator for penetration-free flex contact.
MuJoCo is used to simulate bodies, joints and contact before policies are tested on physical machines, so contact behavior directly affects what a robot learns.
Why it matters
Cleaner flexible-body contact could make experiments with deformable objects more credible, though the new mode is explicitly experimental and needs task-specific testing.
