Genesis World: The Unified Multi-Physics Simulation Platform for Physical AI
Genesis AI's open simulation platform for physical AI: one Pythonic API over a multi-physics engine (rigid, FEM, MPM, PBD, SPH, Stable Fluid, IPC), the Nyx path tracer, and Quadrants, a cross-platform Python-to-GPU compiler. It is built to be the evaluation engine for robot foundation models rather than a data factory: 30,000 parallel environments at 43M FPS, and under a zero-shot real-to-sim protocol, sim-vs-real evaluation agreement of Pearson 0.8996 with mean maximum rank violation 0.0166. Apache 2.0, 29.9k stars.

Genesis World: The Unified Multi-Physics Simulation Platform for Physical AIDexbotic: A One-Stop VLA Toolbox for Pretraining, Fine-Tuning, Inference, and Evaluation
A one-stop VLA toolbox from Dexmal: the unified DexData format spans pretraining, fine-tuning (full/LoRA/RL), inference, and evaluation, supporting mainstream models (π0, CogACT, OFT, MemVLA, GR00T N1) plus the in-house dual-expert DM0; DB-pretraining brings consistent gains across five simulation benchmarks, with 62% average success on RoboChallenge Table30 real-robot evaluation.

ASPIRE is the continual-learning system NVIDIA open-sourced with the University of Michigan, UIUC, Berkeley and CMU (paper arXiv:2607.00272, Apache-2.0). No gradient descent: a coding agent repeatedly writes, runs and repairs robot control programs (code-as-policy) inside a closed-loop execution engine, promotes only verified fixes into a reusable skill library, and uses evolutionary search to escape single-trajectory patching. Driven by Claude Opus 5.5 it averages 99% success across all 80 LIBERO-Pro tasks and 100% on representative Robosuite and BEHAVIOR-1K tasks; perturbed manipulation improves by up to 77%, and unseen long-horizon tasks reach 31% zero-shot against a 4% baseline. On hardware, skills discovered in simulation transfer across embodiments to a real dual-arm station, and online learning even teaches the robot to solve a Rubik's Cube.

ASPIRE: Agentic /Skills Discovery for RoboticsBimo: a 45 cm Open-Source Hip-Head Biped Trained in Isaac Lab and Distilled onto an RP2040
Bimo is a 45 cm, roughly 1.6 kg hip-head biped kit: eight STS-3215 bus servos, a BNO08x 9-DoF IMU, four VL53L0X rangefinders, two 180-degree cameras, and a custom RP2040 board closing a 20 Hz control loop. The repository publishes the Python control API (1023 lines), three MCU firmware builds (1349 lines), a ROS2 wrapper (1431 lines) and an Isaac Lab training environment (874 lines: six reward terms, dense domain randomization, and a system-identified STS3215Actuator with 3.113 Hz bandwidth, directional gear backlash and a 5 ms bus delay), plus a 26MB Bimo.usd model. The CPG gait's 104 Fourier coefficients and per-joint amplitude gains are hardcoded in both Python and C, and a [256,128,64] PPO teacher distills into a [64,32] student that goes through onnx2c into the firmware, so the robot walks untethered on the MCU. All code is Apache-2.0, but the CAD and electronics the README promises are still marked coming soon: no STL, STEP, schematic, gerbers or BOM exist in the working tree or in git history, and neither release ships pretrained weights (zero assets) or a DIY assembly manual. Currently v1.1.0 with 198 stars, in pre-order status.

text-to-cad turns parametric CAD into a local agent skill: plain language or an image becomes a STEP model with STL/3MF/GLB exports, plus DFM review, dimensioned drawings, URDF/SRDF/SDF robot descriptions and 3D printing, sheet metal and CNC integrations. Kernel is build123d on OCP; the shape is twelve skills plus the cadgen engine and a local CAD Viewer. MIT, about 20.6k stars.
