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 …
Intel provides an open source ROS Package for their RealSense D400 series cameras. Here we install the package on a NVIDIA Jetson TX development kit. Looky here: Background The RealSense D400 cameras are the next generation of the Intel RealSense camera product line. In the video, we install a ROS Read more …
With the advent of L4T 28.2, we freshened up the ROS installers for the Jetson TX1 and Jetson TX2. Looky here: Background In a previous article, Robot Operating System (ROS) on NVIDIA Jetson TX2, we discuss the history of ROS and why it has become the most popular operating system 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 …
So you’ve been working on your Jetson TX1 project for a while, and need a little inspiration. It turns out that there’s a group of people at Skydio that put together a very impressive product around the Jetson TX1. Here’s a very nice and informative preview video of the Skydio 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 Note: Newer versions of RACECAR J use a VESC 6. Please see the article RACECAR/J – Programming the Electronic Speed Controller. For RACECAR/J, we replace the Read more …
In the previous article in our RACECAR/J Build Series, we finished the initial assembly of the base robot. Now it is time for the Software Install. FOCBOX replaced by VESC6 Plus Important Note: Currently the RACECAR/J Kits are shipping with the VESC 6 Plus. There are two installation scripts in Read more …
The course MIT 6.S094: Deep Learning for Self-Driving Cars is currently in session. Course instructor Dr. Lex Fridman states that “Our goal is to release 1 lecture every other day until all 20 lectures and guest talks are out. It’s important to me to make this course free and open Read more …
In Part One and Part Two of the RACECAR/J Series, we built the chassis and platform decks. Now it’s time to put them together. Looky here: Introduction Building even a simple robot like RACECAR/J usually means several assembly steps. Now that we’ve built the chassis and the platform decks, it’s Read more …
