Genesis v1.2.3: More Realistic Friction and Rendering

Why it mattersNew physics engine prevents robots from slipping when pushing boxes, renderer handles multiple materials in one pass, LiDAR adds power-saving mode.

Genesis is a robot simulation platform. This update makes the physics world more realistic: robots no longer fake-slip when pushing boxes or screwing, making grasping and dragging more realistic. The renderer now handles rigid, soft, and articulated bodies in one pass, eliminating separate pipelines. LiDAR sensors have a new 'distances-only' mode that skips complex material interactions, significantly reducing CPU load. It also fixes bugs causing model twisting and phantom collisions, making lar

What changed

  • Introduced an elliptic friction cone model for more accurate static friction, preventing robots from fake-slipping when pushing boxes or screwing, making grasping and dragging more realistic.
  • The batch renderer now supports rendering rigid, soft, and articulated bodies together in a single pass, eliminating the need for separate rendering pipelines.
  • Raycasting sensors like LiDAR and depth cameras added a 'distances-only' mode, skipping complex material interactions to significantly cut CPU load for large-scale parallel simulations.
  • Added an option to ignore the default ground plane, making it easier to create custom terrains like slopes and pits, or run zero-gravity floating experiments.
  • Fixed a bug where rotation angle calculations conflicted, preventing unexpected twisting or deformation of models during simulation.
  • Fixed a collision detection bug for plane entities, eliminating phantom collisions or objects bouncing around for no reason.
  • Corrected the mass calculation for attached entities like tools mounted on grippers, ensuring the inertia and wobbling of the robotic arm match real-world physics.

Genesis Simulator v1.2.2: Tactile Sensors for Dexterous Hands and Collision Detection Overhaul

Genesis Simulator v1.2.2 makes robot training more realistic. Dexterous hands now have tactile sensors that simulate real-world imperfections like dead zones, making RL training more realistic. It also completely solves thin-shell tunneling and ghost collisions for complex shapes. If you are running large-scale reinforcement learning training, computation speed and stability have seen significant improvements.

  • Added tactile sensors to dexterous hands that simulate real-world imperfections like dead zones, making RL training more realistic.
  • Upgraded collision detection for complex shapes, completely fixing thin-shell tunneling and spurious contacts.
  • Optimized the no-slip calculation for grasping; it adds less than 20% overhead but makes holding objects much more stable.

dm_control 1.0.44: Physics Engine Upgrade, Adhesive Contacts & Conveyor Effects

dm_control 1.0.44 updates the physics engine MuJoCo to 3.11.0 and introduces several new features. You can now simulate adhesive contacts (contacts that pull like magnets) and conveyor/treadmill effects via surface velocity. For rotational joints (e.g., ball joints), control signals now handle rotations beyond 180 degrees more smoothly. Additionally, preparations for future MIMO actuators split actuator counts into inputs, objects, and outputs.

  • Update to MuJoCo 3.11.0, requiring this version
  • Add SO3 transmission and native orientation actuator for rotational control like ball joints
  • Add geom adhesion: contacts that pull via translated friction cones

Pink v4.3.0: Fix braking-distance calculation for continuous joints

Pink is a Python library for robot kinematics. This release fixes a critical bug where the braking-distance term in AccelerationLimit was incorrect for joints without configuration limits, such as continuous joints. It also updates the list of revolute-joint shortnames supported by ManipulabilityTask, and adds support for Python 3.13 and 3.14. New examples and dependencies are included.

  • Fixed braking-distance calculation in AccelerationLimit for continuous joints
  • Updated the list of revolute-joint shortnames supported by ManipulabilityTask
  • Added support for Python 3.13 and 3.14
