What is a simulator ROS bridge? Simulator simulator_bridge ROS based application stack Subscribes to commands to be applied in the simulator simulator Publishes simulator’s control commands Subscribes to ROS2 topics from the bridge Publishes sensor data as ROS2 messages Simulator commands request for sensor data Sensor data simulator’s

functionalities without modifying their compilers or breaking existing codebases. stl- preview works as a bridge, so the user can simply change the namespace from preview to std whenever they decide to use the 3. Discussion Although stl-preview can replace existing STL, its primary role is to serve as a bridge to the latest standard. Some core functionalities like coroutines or reflections cannot be implemented

Orthogonal Design Examples (continued) • Designs leveraging orthogonal behavior: Implementation Bridge: API provides no interface for an essential internal operation (which is internally bridged through interface is independent of internal execution and implementation Example: Synchronous/Asynchronous bridge (such as to implement proactive or reactive read/write) Fire-And-Forget: Function immediate-return

tasks that run on real life devices like embedded devices, phone, etc, do not have access to GPU. To bridge that gap, micrograd++ let’s any user train a neural network in C++ and ship that to any edge device
