Here’s how we got our Jetson Nano working reliably with an Intel Wireless AC 3165 PCIe WiFi card. This post outlines the steps someone else used to solve this issue on the Nvidia developer forums, but the solution was spread over multiple posts whereas this one puts all those steps in one place.

For years, power has always been something we have constantly been seeking to improve. Most robots and other remote/portable applications utilise LiPo batteries. While flexible and providing lots of power in a small package, LiPo batteries do have a lot of concerning characteristics. In particular, they are quite prone to overheating and catching fire, as...Read More

The new polyurethane tires were excellent, they had plenty of grip, were basically indestructible and they maintained their grip over many hours of use.

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...Read More
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...Read More

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...Read More
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. The algorithms used in this part are by far the most complicated. Rather...Read More
