TREK2

TREK2 is an open-source software framework designed to support development and coordination of autonomous systems and real-time data processing. As the successor to TREK1, TREK2 emphasizes modularity, portability, and interoperability across robotics platforms and field operations.

Development and governance: The project is led by the TREK Consortium, a collaboration of universities and industry partners. Initiated in 2020, TREK2 uses a permissive license (MIT) and operates under a community-driven governance model that includes a steering committee and regular public roadmaps.

Architecture: TREK2 provides a lightweight core runtime, a plugin system for sensors, actuators, planners, and perception modules, and a publish–subscribe messaging layer. It offers compatibility with ROS 2, language bindings for Python and C++, and containerized deployment through Docker and Kubernetes.

Features: The framework supports real-time task scheduling, deterministic execution latency, fault isolation, and secure communications with authentication and encryption. A simulator bridge enables testing with common robotics simulators such as Gazebo. It is designed to run on edge devices as well as cloud-based orchestration.

Applications and impact: TREK2 is used in academic research and industry for autonomous mobile robots, unmanned aerial systems, and automated manufacturing equipment, enabling data fusion, localization, and navigation tasks.

Reception and status: As of the mid-2020s, TREK2 has an active developer community and regular releases. Critics point to reliance on external middleware, while supporters highlight modularity and ROS 2 integration.
