New features

  1. Added simulation on GPU and TPU via the new MuJoCo XLA (MJX) Python module. Python users can now natively run MuJoCo simulations at millions of steps per second on Google TPU or their own accelerator hardware.

    • MJX is designed to work with on-device reinforcement learning algorithms. This Colab notebook demonstrates using MJX along with reinforcement learning to train humanoid and quadruped robots to locomote: Open In Colab
    • The MJX API is compatible with MuJoCo but is missing some features in this release. See the outline of MJX feature parity for more details.

  2. Added new signed distance field (SDF) collision primitive. SDFs can take any shape and are not constrained to be convex. Collision points are found by minimizing the maximum of the two colliding SDFs via gradient descent.

    • Added new SDF plugin for defining implicit geometries. The plugin must define methods computing an SDF and its gradient at query points. See the documentation for more details.

  3. Added new low-level model element called flex, used to define deformable objects. These simplicial complexes can be of dimension 1, 2 or 3, corresponding to stretchable lines, triangles or tetrahedra. Two new MJCF elements are used to define flexes. The top-level deformable section contains the low-level flex definition. The flexcomp element, similar to composite is a convenience macro for creating deformables, and supports the GMSH tetrahedral file format.

    • Added shell passive force plugin, computing bending forces using a constant precomputed Hessian (cotangent operator).

      Note: This feature is still under development and subject to change. In particular, deformable object functionality is currently available both via deformable and composite, and both are modifiable by the first-party elasticity plugins. We expect some of this functionality to be unified in the future.

  4. Added constraint island discovery with mj_island. Constraint islands are disjoint sets of constraints and degrees-of-freedom that do not interact. The only solver which currently supports islands is CG. Island discovery can be activated using a new enable flag. If island discovery is enabled, geoms, contacts and tendons will be colored according to the corresponding island, see video. Island discovery is currently disabled for models that have deformable objects (see previous item).

  5. Added mjThreadPool and mjTask which allow for multi-threaded operations within the MuJoCo engine pipeline. If engine-internal threading is enabled, the following operations will be multi-threaded:

    • Island constraint resolution, if island discovery is enabled and the CG solver is selected. The 22 humanoids model shows a 3x speedup compared to the single threaded simulation.
    • Inertia-related computations and collision detection will happen in parallel.

    Engine-internal threading is a work in progress and currently only available in first-party code via the testspeed utility, exposed with the npoolthread flag.

  6. Added capability to initialize composite particles from OBJ files. Fixes #642 and #674.

General

[!IMPORTANT] Breaking API changes

  1. Removed the macros mjMARKSTACK and mjFREESTACK.

    Migration: These macros have been replaced by new functions mj_markStack and mj_freeStack. These functions manage the mjData stack in a fully encapsulated way (i.e., without introducing a local variable at the call site).

  2. Renamed mj_stackAlloc to mj_stackAllocNum. The new function mj_stackAllocByte allocates an arbitrary number of bytes and has an additional argument for specifying the alignment of the returned pointer.

Changelog

Sourced from mujoco's changelog.

Version 3.1.3 (March 5th, 2024)

General ^^^^^^^

  1. Added the :at:inheritrange attribute to :ref:position<actuator-position> and :ref:intvelocity<actuator-intvelocity> actuators, allowing convenient setting of the actuator's :at:ctrlrange or :at:actrange (respectively), according to the range of the transmission target (joint or tendon). See :ref:position/inheritrange<actuator-position-inheritrange> for details.
  2. Deprecated :ref:mj_makeEmptyFileVFS in favor of :ref:mj_addBufferVFS. :ref:mjVFS now computes checksums of its internal file buffers. :ref:mj_addBufferVFS allocates an empty buffer with a given name in an mjVFS and copies the data buffer into it, combining and replacing the deprecated two-step process of calling :ref:mj_makeEmptyFileVFS followed by a direct copy into the given mjVFS internal file buffer.
  3. Added :ref:mj_angmomMat which computes the 3 x nv angular momentum matrix :math:H(q), providing the linear mapping from generalized velocities to subtree angular momentum :math:h = H \dot q. Contribution by :github:user:v-r-a.

MJX ^^^

  1. Improved performance of getting and putting device data.

    • Use tobytes() for numpy array serialization, which is orders of magnitude faster than converting to tuples.
    • Avoid reallocating host mjData arrays when array shapes are unchanged.
    • Speed up calculation of mjx.ncon for models with many geoms.
    • Avoid calling mjx.ncon in mjx.get_data_into when nc can be derived from mjx.Data.

  2. Fixed a bug in mjx-viewer that prevented it from running. Updated mjx-viewer to use newer mjx.get_data_into function call.

  3. Fixed a bug in mjx.euler that applied incorrect damping when using dense mass matrices.

  4. Fixed a bug in mjx.solve that was causing slow convergence when using mjSOL_NEWTON in :ref:mjtSolver.

  5. Added support for :ref:mjOption.impratio<mjOption> to mjx.Model.

  6. Added support for cameras in mjx.Model and mjx.Data. Fixes :github:issue:1422.

  7. Added an implementation of broadphase using top_k and bounding spheres.

Python bindings ^^^^^^^^^^^^^^^ 11. Fixed incorrect data types in the bindings for the geom, vert, elem, and flex array members of the mjContact struct, and all array members of the mjrContext struct.

Version 3.1.2 (February 05, 2024)

General ^^^^^^^

  1. Improved the :ref:discardvisual<compiler-discardvisual> compiler flag, which now discards all visual-only assets. See :ref:discardvisual<compiler-discardvisual> for details.
  2. Removed the :ref:timer<mjtTimer> for midphase colllision detection, it is now folded in with the narrowphase timer. This is because timing the two phases seperately required fine-grained timers inside the collision
