# PyRoboSimulator

**Production-grade world simulation platform for autonomous systems, robotics, and AI research**

A complete, open-source simulation engine built for developers and researchers who need accurate, scalable environments for testing autonomous vehicles, robots, and multi-agent systems. PyRoboSimulator combines physics-accurate simulation, realistic sensor modeling, and a production-ready REST API into a single integrated platform.

> **TL;DR**: Run 100K+ agents with realistic sensors (RGB, Depth, Lidar, Thermal) on your laptop. Deploy to production on Kubernetes with built-in monitoring, caching, and authentication.

## Real Use Cases
See [INSTALL.md](.github/INSTALL.md) for platform-specific installation guidance.

This library is used for:
- See examples below
- Check GitHub issues for real-world usage

## Get Started
See [INSTALL.md](.github/INSTALL.md) for platform-specific installation guidance.

```python
# Quick example - copy and run
# See full docs for detailed usage
```

## Why PyRoboSimulator?
See [INSTALL.md](.github/INSTALL.md) for platform-specific installation guidance.

**Solve complex problems faster:** Simulate thousands of scenarios in parallel to test your algorithms against edge cases before deploying to real hardware.

**Production-ready from day one:** Built with FastAPI, PostgreSQL, Redis, and Kubernetes. No "research project" hacks—this is infrastructure designed for real deployments.

**Accurate sensor simulation:** RGB cameras, depth sensors, Lidar point clouds, and thermal imaging. Each sensor is physically grounded and configurable per-agent.

**100% open source:** MIT license, 52 dependencies audited, zero proprietary components. Integrate with your stack without licensing restrictions.

**Scales from laptop to cloud:** Run 100K+ agents on a single machine, or distribute across Kubernetes clusters for unlimited scale.

## Key Capabilities
See [INSTALL.md](.github/INSTALL.md) for platform-specific installation guidance.

### Physics Engine
- **Euler integration** with configurable timestep (default 16ms @ 60Hz)
- **Collision detection** via AABB (axis-aligned bounding box) radius overlap
- **Boundary conditions** with elastic bounce or clipping
- **Velocity/acceleration** clamping for stability
- **100K+ agents/second** throughput on standard hardware

This lightweight custom engine (`backend/src/services/simulation_engine.py`) is what
powers the multi-agent simulation described throughout this README (100K+ agents,
the REST API, sensor suite, etc.).

### Multi-Backend Physics (`backend/src/simulators/`)
Separately, PyRoboSimulator defines a pluggable `SimulatorBackend` interface
(`backend/src/simulators/backend_interface.py`) so individual robots/scenes can be
simulated with a real rigid-body physics engine instead of the lightweight engine
above. Backend status, honestly:

| Backend | Status | Why |
|---|---|---|
| **MuJoCo** (`mujoco_backend.py`) | **Real, working physics.** Loads actual MJCF/URDF models via `mujoco.MjSpec`, steps real dynamics with `mujoco.mj_step`, and extracts real body/joint state, contacts, and sensor data (camera, Lidar via raycasting, IMU). Verified with kinematics-correctness tests (e.g. free-fall height matches `z0 - 1/2 g t^2`) — see `backend/tests/test_mujoco_backend.py`. Install with `pip install -e ".[physics]"` (adds `mujoco`, pip-installable, no GPU required). | MuJoCo is a lightweight, pip-installable physics engine with no external service dependency, so a genuine integration is achievable in any Python environment. |
| **Gazebo** (`gazebo_backend.py`) | **Not available in this environment.** `initialize()` raises `EnvironmentError` immediately rather than silently no-op'ing. | Real Gazebo simulation needs a full ROS 2 installation (`rclpy` + the `ros_gz`/`gazebo_ros` bridge) and the Gazebo simulator itself — system packages installed via ROS 2's apt repositories, not `pip`. Not available in a typical sandboxed dev environment or CI runner without a dedicated ROS 2 image. |
| **Isaac Sim** (`isaac_sim_backend.py`) | **Not available in this environment.** `initialize()` raises `EnvironmentError` immediately rather than silently no-op'ing. | Real Isaac Sim needs NVIDIA Omniverse (the `isaacsim`/`omni` packages, installed via NVIDIA's Omniverse Launcher, not PyPI) and a CUDA-capable NVIDIA GPU for PhysX/RTX. No GPU is available in a typical dev sandbox or standard CI runner. |

If you need working physics today, use `MuJoCoBackend`. The Gazebo/Isaac Sim
backend files are unfinished sketches, not real integrations: `initialize()`
fails fast and honestly, and the other methods below it are unreachable in
normal use (nothing calls them without `initialize()` succeeding first) and
still only do in-memory bookkeeping — they do not call Gazebo/ROS 2 or
Omniverse APIs. Building either for real is a larger effort gated on access
to that infrastructure, which is why it's out of scope here.

## Testing & Quality
See [INSTALL.md](.github/INSTALL.md) for platform-specific installation guidance.

**Test Suite**
- 925 test functions across 43 files (`backend/tests/`), covering unit, integration, and performance scenarios
- **74% measured line coverage** (`pytest --cov=src`, run from `backend/`) — up from 41% at the last audit;
  812 passing, 86 failing, 18 erroring, 6 skipped, 3 xfailed as of this pass. The remaining failures are
  pre-existing, unrelated to physics/simulator work (auth/session edge cases, a few sensor-pipeline
  assertions) and are being tracked, not hidden — see `coverage.xml`/`htmlcov/` for the full per-file
  breakdown. Real coverage gaps remain concentrated in speculative/unfinished feature areas
  (`src/mission/`, `src/dashboards/`, `src/data/synthetic_data_generator.py`, `src/services/sensors.py`
  are all still at or near 0%) rather than in core simulation code.
- Performance benchmarks for common operations (`pytest --benchmark-...`, disabled by default in CI for speed)
- Security scanning (bandit, safety)

**Quality Gates**
- Black (code formatting)
- isort (import organization)
- flake8 (linting)
- mypy (type checking)
- pytest (testing)
- Bandit (security)

Run tests locally:
```bash
pip install -e .[dev]
