In this tutorial, we will create a ROS Range publisher Node on Arduino that publishes HC-SR04 ultrasonic sensor readings on ROS “/ultrasound” topic using rosserial and how to read range topic readings in ROS. Before that, we will introduce you to HC-SR04 sensor and interface it with Arduino to build the Arduino ROS range publisher … Read more
In this tutorial, we will show you how to subscribe to ROS topics using Arduino rosserial. We will see how to set up a ROS node on Arduino that we will receive data on a specific topic from ROS. In a previous tutorial, we introduced you to ROS and how to set it up with … Read more
In this tutorial, we will show you how to use rosserial with Arduino IDE and ROS (Robotic Operating System) and how to setup a ROS node on Arduino. Rosserial Arduino is a middleware software framework that combines with Arduino to build intelligent robotic models. We will use Arduino 1.8.19 with ROS Melodic in Ubuntu 64 … Read more
