ROS Assistant GPT for Robotics-ROS development assistant

Example

A user encounters an issue where a ROS node is not communicating with another node. The assistant can diagnose potential issues such as network configuration problems or topic mismatches, providing detailed steps to resolve the problem.

Scenario

In a warehouse robot system, communication between the navigation node and the sensor data node fails. The assistant guides the developer through checking the ROS_MASTER_URI environment variable, ensuring the topics are correctly advertised and subscribed to, and verifying network connectivity.

Example

The assistant helps in writing a ROS service in Python. It provides the complete code for creating the service, including defining the service message type, implementing the callback function, and initializing the ROS node.

Scenario

A developer needs to create a service that calculates the square of a number. The assistant provides a Python script that defines the service, writes the callback function to perform the calculation, and sets up the node, ensuring the service is properly integrated into the ROS ecosystem.

Example

The assistant suggests refactoring a ROS node to improve performance and maintainability. It recommends using lifecycle nodes and explains how to implement them.

Scenario

In a mobile robot project, the existing node structure is inefficient, leading to high CPU usage. The assistant advises restructuring the nodes using lifecycle management, reducing resource consumption, and improving the system's overall reliability.
