Parameters in ROS2 What are Parameters? Parameters in ROS2 serve as configuration values for nodes, functioning similarly to variables that can be modified to alter node behavier dynamically. They provide a mechanism for runtime configuration without requiring code changes. Supported Paramter Types...
Topic Communication in ROS2 Topics serve as a fundamental communication mechanism in ROS2, implementing a publish-subscribe model where one node publishes data to a topic and other nodes can subscribe to receive that data. Publish-Subscribe Model The publish-subscribe architecture supports: One-to-o...
Method 1 - Backup within the Nano System Start the Nano and enter the system. Insert a USB drive and check if it is automatically mounted. If not, mount it manually. sudo fdisk -l The green box shows the SD card system information, which is the path for backing up the system. The red box shows the...
This tutorial demonstrates how to model a walking robot using URDF, publish its state as tf2 messages, and visualize the simulation in Rviz. We'll create a URDF model describing the robot's assembly, implement a node to simulate motion and publish joint states and transforms, and use robot_state_pub...
