A Blog Post About Two-Way Audio

A brief history of two-way audio In previous years, we have used a few methods to do two-way audio. Initially we had a speech to text and back again system to transmit data. Needless to say, this was quite limiting and not particularly… well, good. This was replaced in 2018 with Mumble, a basic VoIP...

SIGHTS Set On The Future

Here at S.A.R.T. we are proud to announce the release… of SIGHTS. No, it’s not a network of spy satellites. We aggressively forced the name for that sweet secret service-style acronym. It stands for “SART Integrated GUI and Host Teleoperation Service”, and that’s just what it is: A complete teleoperation interface written by the Semi-Autonomous Rescue...

The Cops Get Involved

On the 16th of October 2019, the Australian Federal Police Bomb Response unit was called to the premises of SFX. Fortunately, it wasn’t because there was a threat of a LiPo fire (this time), but they were there to let us play around with get inspiration from some of their robots. The Bomb Response unit...

Hazmat Part 3: Choosing the Class

Hey there, it’s Anthony, ready to bring an end to this epic trilogy of identifying hazmat signs. In this part we will cover how we solved the second half of the generic object detection problem (as detailed in the first part): classification.

Hazmat Part 1: Detecting the Danger

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...

Using the UDOO x86’s Arduino with Arduino-CLI

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...

Mmmmmm. Yummy PyPot.

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...
