Intro I came across a discussion on the DonkeyCar discord server about Hall effect sensors that can measure speed using Hall effect sensors and gears. Intrigued, I decided to do some research and came across an IC that seemed suitable for the task, utilizing a similar concept. I was specifically looking for a method to measure speed […]

In this post, we will discuss how to access the Realsense camera sensors on the NVIDIA Jetson Nano using ROS 2 Foxy. However, before we delve into that, let’s take a moment to recap what we have accomplished thus far. Introduction to my Jetson based Robot – DonkeyJet ROS 2 on Jetson Nano using Docker,

In our earlier post, I discussed reading joystick input in a ROS node. Now, I’m interested in learning how to utilize the joystick values to control the motors. Hardware There are two types of motors on board: a servo for steering and a DC motor for throttle control. Both are connected to an Electric Speed

Let’s get started with writing our first ROS 2 node! This particular node will be responsible for publishing commands received from the Bluetooth controller, and we will create a new message type for it using C++. If you’re new to ROS 2 nodes, I highly recommend taking some time to familiarize yourself with the basics.

Why ROS 2 and Docker One of my primary objectives is to acquire knowledge on ROS 2, and I strongly believe that this project would be an excellent opportunity to utilize ROS 2. Moreover, I am convinced that Docker could play a crucial role in this project, providing multiple benefits as follows: Docker can facilitate cross-compiling and building

Introducing my ongoing robotics project, currently named DonkeyJet, inspired by the Donkey Car project. This mobile robot is built on an RC car frame and powered by Jetson Nano, providing a hands-on platform for practicing robotics knowledge. The goal is to continually enhance its capabilities while exploring various aspects of robotics technology. While I’m not
