In order to get access to cameras using OpenCV on the NVIDIA Jetson AGX Xavier, you need to build the library from source. Looky here: Background Using JetPack 4.1, you may install OpenCV as an option. However, that particular version of OpenCV does not support CUDA or camera input. What Read more …
The NVIDIA Jetson AGX Xavier GPIO Header Pinout table has been updated with the Linux GPIO numbering and work sheets mapping the Tegra pins all the way to the GPIO Expansion Header. Note: The table is kept on a separate web page for easier maintenance. There’s a lot of info Read more …
For robotics application, one of the leading set of tools is Robot Operating System (ROS). The version of ROS that runs on the Jetson AGX Xavier is ROS Melodic. Installing ROS on the Jetson Xavier is simple. Looky here: Background ROS was originally developed at Stanford University as a platform Read more …
NVIDIA recently began shipping a new product, the Jetson AGX Xavier Developer Kit. Looky here: Jetson AGX Xavier Overview The Jetson Xavier is the next generation of the Jetson line of development kits. Xavier ups the game from the previous generation Jetson TX2. The Jetson Xavier introduces a new module Read more …
This is the first step of building a RACECAR/J. Here we prepare the chassis by removing parts we do not use, and upgrading the springs and bumper. Looky here: Background RACECAR/J is derived from the open source MIT RACECAR, an “open-source powerful platform for robotics research and education”. The first Read more …
JetPack 3.0 is a tool that installs the software tools and operating system for a Jetson Development Kit. In the following video, JetPack installs on a Jetson TX2 Development Kit. Looky here: Note: Catherine Ordun has a quite wonderful blog post Setting up the TX2 using JetPack 3.2, which is Read more …
One of the first things people like to do with their RACECAR is gather data. Using ROS we can record and playback actions. It’s easy! Looky here: Background The usual note here: You should definitely have the book “Programming Robots with ROS, a practical introduction to the Robot Operating System” Read more …
Exploring ROS is easy using the both the built-in tools and additional GUI based tools. Looky here: This is a little different than most the content on JetsonHacks. Basically we bring up a running ROS system using the MIT RACECAR stack and take a look around. This gives some background Read more …
After completion of the RACECAR/J robot assembly, ROS software installation and VESC programming, it is time to test teleoperation using a game controller. Looky here: Background In the software installation article, we installed a custom ROS software stack for the MIT RACECAR. There is a special node, joy_teleop, which is Read more …
In the first part of our Hokuyo UST-10LX installation article, we made a wiring harness and installed the lidar into RACECAR/J. After connecting the Jetson on the RACECAR to an HDMI monitor, keyboard and mouse we are ready to configure the Hokuyo and test it under ROS. Looky here: Hokuyo Read more …
Adding a Hokuyo UST-10LX Scanning Range Finder to RACECAR/J is probably the most difficult task in the build to replicate a MIT RACECAR. With a little patience, it’s not too difficult. Looky here: Background One popular approach to vehicle autonomy is to add lidar and use the output to map Read more …
Before we can run RACECAR/J, we need to program the electronic speed controller, called a VESC, for the motor and steering. Looky here: Background For RACECAR/J, we replace the stock TRAXXAS ESC with Vedder Electronic Speed Controller (VESC) version 4.12 compatible hardware. The major reason for the change is to Read more …
Viraj Padte from Oklahoma has been working on building a JetsonBot based on the articles posted on JetsonHacks. Background Viraj has a bachelor’s degree in Electronics and Telecommunications Engineering. Viraj has an interesting motivation for building a JetsonBot. Viraj states, “I choose to make the JetsonBot in order to learn Read more …
Jared Langbart from Columbia, Missouri has been working on building a JetsonBot based on the articles posted on JetsonHacks. Background Jared has a degree in Biotechnology and enjoys his work at a local hospital. Despite not having any formal computer or engineering training, Jared decided to build a JetsonBot to Read more …
The ability to play sound on a robotic platform provides an interesting dimension of interactivity. Looky here: Installation The addition of sound to a robot provides a wide variety of possibilities to expand the level of interactivity of the device. Fortunately this is easy to add to the JetsonBot. The Read more …
