Really excited to release mjviser, a web-based MuJoCo viewer, powered by Viser. It has almost all the features of the native MuJoCo viewer, but runs in your browser. Load and simulate any MuJoCo model with a single uv command 👇 uvx mjviser

wow i literally built a crappy version of this for my (relatively basic) needs so cool to see a full featured version of this concept 🔥

Awesome! I was literally looking for something like this earlier today when I was prepping to port a new bot into mjlab

What's the difference between this and the Vizer in MJLAB?

Kevin Zakka6 months ago

It’s basically the mjlab viewer, but standalone. mjlab will directly depend on it in an upcoming PR. For context, some users wanted the viewer for other non RL projects, so decided to separate it out to be maximally useful.

hey @kevin_zakka quick q abt mjx/warp :) in practice, can you backprop through a long contact-rich trajectory w.r.t. contact params, or is that only reliable under specific smoothing assumptions / only in MJX-JAX and not MJWarp?

Wow this looks great! No more mjpython?!

How does performance compare to the native viewer? Seeing that many humanoid models running smoothly in the browser is surprising. Or just my graphic card sucks?

Kevin Zakka6 months ago

The 100 humanoid example is running C MuJoCo. The viewer works for both C mujoco and Mujoco Warp.

Of course mjlab supports the native MuJoCo viewer. Makes it a breeze to pause, slow down, inspect contacts, perturb the robot, etc. There's also a brand new pane for reward visualization :)

mjlab v1.3.0 is out! It's packed with features: a revamped viewer built on mjviser, a preset-based terrain system, simplified actuator config, and new MDP primitives. Here's a Go1 quadruped trained in the stair terrain with the new terrain-aware foot height sensor.

The first universal 3D robot viewer for the browser… load URDF, MJCF, or USD in seconds. No installs. No setup. Developer Victor Oldensand has built Mechaverse, a universal 3D robotics viewer that works on desktop and even mobile (if your phone is strong enough). No installs. No setup. Just drag and drop your robot model. Mechaverse merges and improves the work of several open-source projects, including: ✅ Mujoco_wasm (MuJoCo in the browser) ✅ USD-viewer (OpenUSD) ✅ URDF-loaders … into one clean, cross-platform tool. 💻 Try it here: Built in just 4 days, it supports URDF, MJCF, and OpenUSD formats via Three.js, with rendering powered by WebAssembly. Perfect for quickly inspecting robot models or scenes without heavyweight desktop software.

Guess whose state of the art rigid body simulator that can support up to 200k rigidbodies is accurate enough for the microduck to walk in Not a single bit of this is run with mujoco. This is entirely my rigid body simulator (based on box3d) and runs entirely on cuda

Ever wanted to simulate an entire house in MuJoCo or a very cluttered kitchen? Well now you can with the newly introduced sleeping islands: groups of stationary bodies that drop out of the physics pipeline until disturbed. Check out Yuval's amazing video and documentation 👇

The ultimate test of any physics simulator is its ability to deliver real-world results. With MuJoCo Playground, we’ve combined the very best: MuJoCo’s rich and thriving ecosystem, massively parallel GPU-accelerated simulation, and real-world results across a diverse range of robot platforms: quadrupeds, humanoids, dexterous hands, and arms. Best of all? You can get started today with a single command: pip install playground

This is a demonstration video of in-hand object rotation with new Torobo Hand. By leveraging large-scale parallel reinforcement learning in NVIDIA Isaac Sim, the learned policy can perform object manipulation in MuJoCo and on the real robot without any additional training.

Someone built a Chromium browser that runs entirely in your terminal. It's called Carbonyl, and it renders actual web pages in your command line. The best part is it runs with 0% CPU usage when idle. - Full Chromium engine in the terminal. - dles at exactly 0% CPU. - Fast, lightweight, and completely terminal-native. 100% Open Source.

Pretty excited about the new SuperDex robotics simulator by Meta. 1. It's contact-first simulator in C++ designed for smooth, non-convex rigid–soft physics (vs mujoco designed for convex shapes) 2. Rather than standalone simulator, it includes a full suite of tools (RL/gym environments ("Superdex Lab"), GUI authoring tool ("Superdex Studio"), VR teleop). 3. It runs well on Mac! Trying it out below:

hi all, excited to join! i'm building an expressive mini "shoggoth" robot which will eventually be hooked up to gpt4o realtime voice. i'm currently working on the low-level policies, which are trained in a mujoco simulation with RL. to delay working on raw-pixels for now, i trained a pose-estimation model using deeplabcut and triangulate the position in 3d space using the stereo cameras. eventually, i'll use gpt4o's tool calling capabilities to activate several of these policies (closed and open loop) based on the dialog flow! captions: manual actuation of the tentacle / 3d pose estimation / target design

🚀 GeoLibre just passed 5,000 stars on GitHub, in only two months! GeoLibre went public on May 27, and the community has already pushed it past 5,100 stars and 500+ forks. Thank you to everyone who starred, forked, filed issues, opened pull requests, and shared the project. For those just discovering it: GeoLibre is a free and open-source, lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It runs everywhere you do, in the web browser, on the desktop, on mobile, and inside Jupyter notebooks, all while keeping your data local and private. Key features of GeoLibre: - Runs anywhere: the same app ships as a native desktop app, a browser web app, a native Android app, and a Jupyter widget. - Local and private by default: load and analyze GeoJSON, GeoParquet, GeoPackage, Shapefile, COG, LiDAR, 3D Tiles, and more, right in the browser. - Powered by open source: built on MapLibre GL JS, DuckDB-WASM Spatial, Tauri, React, and TypeScript. - Spatial SQL in the browser: query your data with DuckDB Spatial, PostGIS via PGlite, and Apache Sedona. - Extensible: a growing plugin system for cloud data, federal web services, and custom tools. - Supports 12 planetary basemaps: Earth, Mars, the Moon, Mercury, Venus, and more. Two months in, we have already shipped 25 releases, the latest being v2.4.0. There is a lot more to come, and the best way to shape it is to jump in. Try it out - Launch GeoLibre Web: - GitHub: - Documentation: - Release notes: If GeoLibre is useful to you, a star on GitHub and a share here go a long way. Thank you for an incredible first two months. #geospatial #opensource #MapLibre #GeoLibre
