Hi, this is Anthony. I’ve not written a blog post about the vision stuff yet because I’ve been too busy actually working on it. The competition is done now though, and so I have free time to talk about what I’ve learned. Basically, there are two parts to the generic object detection problem: detection and...Read More

In a previous blog post, I wrote about using the official Arduino IDE with the on-board Arduino 101 on the UDOO x86 Ultra. Since our robot is headless, i.e. doesn’t run a display server, we wanted the IDE to run from the command line. While the IDE had support for using its functionality from the...Read More
Hello, It’s me Barney again! This time I am writing about motors. The S.A.R.T team ran into an issue with the motors constantly overloading and not going to the desired speeds. After a little troubleshooting, the issue was found. The pyax12 library doesn’t support the new MX-12w motors. I decided to replace the library with...Read More
Hello! It’s Barney again. I am here to give a few updates regarding S.A.R.T’s progress, considering we haven’t had an update for cough two months cough. We decided to remove the Xirrus XR-600 from the control unit and we are going to replace it with the Unifi AP AC PRO because the Xirrus access point...Read More

At the end of 2018 we were gifted a TurtleBot3 Burger by our new sponsor, Tribotix. A TurtleBot is a low cost robot that we built over a day during the holiday workshop. The TurtleBot has a Raspberry Pi 3 (Model B) and a 360° LiDAR, 3-Axis gyroscope, 3-Axis accelerometer and 3-Axis magnetometer sensors, OpenCR...Read More
Say hello to SFX’s new SART team! This year’s team consists of three year 11’s, Barney Bruckner, Martin Hosking, Anthony Gambale and two year 12’s, Michael Cavalli, and myself, Charlotte Drury. Barney’s role is in Autonomy. Barney’s been charging ahead with basic self-navigation and looking into ROS (Robot Operating System) as an option. Please refer...Read More
Hello! I am Barney, I’ll be taking over autonomy for the next two years for S.A.R.T. This post isn’t actually about the progress of autonomy, but rather my plans for it. The main goal for the Mk 4, is to be able to follow the left wall throughout the course. Though this will be inefficient...Read More
An issue we’ve commonly faced while operating our robot is that the servos will keep spinning if the script crashes or if we exit the script via CTRL+C. I’ve always had the stop_servos.py script for this exact purpose but it has to be executed manually after exiting the main script, i.e. python3 stop_servos.py. This script...Read More
