Where Light Becomes Data

Project Iris is a full-featured Unreal Engine plugin enabling direct integration with ROS 2 via Fast DDS. It serves as a high-performance messenger between Unreal’s virtual worlds and ROS 2 robots, allowing real-time sensor streams, control signals, and data to flow seamlessly.

Built on the robust DDS (Data Distribution Service) framework, Project Iris emphasizes **speed**, **reliability**, and **ease of use**. Whether you’re an internal developer prototyping robotics simulations, a researcher pushing the limits of sensor realism, or a marketplace user seeking plug-and-play ROS 2 connectivity, Project Iris delivers a solution tailored to your needs.

Why Project Iris?

Seamless ROS 2 Integration: Leverages Fast DDS for native ROS 2 communication without bridges or external adapters, ensuring minimal latency and maximum throughput:contentReference[oaicite:2]{index=2}.
Full Sensor & Actuator Support: Transmit camera images, LiDAR scans, IMU data, joint states, and more using built-in support for standard ROS 2 messages (e.g. std_msgs, sensor_msgs, geometry_msgs):contentReference[oaicite:3]{index=3}.
High Performance Networking: Achieve real-time updates with DDS Quality of Service tuning. Fast DDS optimizations (like zero-copy transport) enable reliable high-frequency data exchange:contentReference[oaicite:4]{index=4}.
Easy to Use: Blueprint-friendly components let non-ROS developers connect Unreal assets to ROS 2 topics visually:contentReference[oaicite:5]{index=5}. No separate ROS 2 installation is required to get started:contentReference[oaicite:6]{index=6}.
Cross-Platform & Scalable: Compatible with Unreal Engine 5 on both Windows and Linux (with planned support for other platforms). Scales from single-robot tests to distributed simulations with multiple participants in the DDS network.

IrisCore

The **engine** of Project Iris. Manages Fast DDS communications, domain participants, and message serialization. IrisCore handles all low-level data transport, ensuring that information travels efficiently between Unreal and ROS 2.
