Packages created using ROS Sugar
Kompass: a framework for building robust and comprehensive event-driven navigation stacks using an easy-to-use and intuitive Python API
ROS Agents: a fully-loaded framework for creating interactive embodied agents that can understand, remember, and act upon contextual information from their environment.
Overview
ROS Sugar is built for ROS2 developers who want to create robust, event-driven systems with multiple nodes that are easy to use and can be configured and started with an intuitive python API. It provides primitives for writing ROS nodes and events/actions which can start/stop/modify the nodes, in the spirit of event driven software standard. ROS Sugar is also a replacement for the ROS Launch API.
A Component is the main execution unit in ROS Sugar, each component is configured with Inputs/Outputs and Fallback behaviors. Additionally, each component updates its own Health Status. Components can be handled and reconfigured dynamically at runtime using Events and Actions. Events, Actions and Components are passed to the Launcher which runs the set of components as using multi-threaded or multi-process execution. The Launcher also uses an internal Monitor to keep track of the components and monitor events.
