## Health v2 (maintenance only)
Score: 23/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 8, longevity 100
- inputs: {"age_days": 2984, "days_push": 1247, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
SVL Simulator is a Unity-based multi-robot simulator for autonomous vehicles with ROS/ROS2 integration, sensor simulation, and Python APIs. LG suspended active development on January 1, 2022, and the project is no longer maintained.

## Use cases
- simulate self-driving car sensors like lidar and cameras
- test autonomous driving stacks with ROS or ROS2
- generate synthetic training data for perception models
- run reinforcement learning experiments in driving scenarios
- validate Autoware or other AD software in simulation

## When to choose
- you need a free open-source AV simulator with ROS integration and can build it yourself
- you are working with legacy Autoware or SVL-based research pipelines
- you want to fork and maintain a Unity-based driving simulator

## When to avoid
- you need an actively maintained simulator with support and updates
- you rely on the WISE cloud service, which has been shut down
- you want a supported alternative like CARLA or AirSim forks

## Facets
- artifact type: application
- maturity: abandoned
- function: simulation, machine-learning, computer-vision, robotics
- domain: autonomous-vehicles, simulation, robotics, machine-learning
- platform: windows, cross-platform
- tags: autonomous-driving, ros, ros2, unity, self-driving-car, sensor-simulation, discontinued, linux
