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 …

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 …
