Updates to Burro self-driving platform

I’ve been busy implementing some cool updates to Burro, the self-driving RC car/robot platform I’m building. Here’s a summary: The Adafruit Motor HAT is now supported in addition to NAVIO2. Both boards are fully supported , and in fact you can use the same SD card in different cars/robots, without the need to reinstall anything, as

VL53L0X as an Altitude Rangefinder

I recently ordered a VL53L0X sensor carrier from Pololu, with the aim of using it as a lightweight rangefinder for my latest build. VL53L0X is a Time-of-Flight (ToF) sensor; it measures distance by measuring the time it takes for a pulse of light to travel to a target and back. This is some serious stuff for

On the Road to a Full-CF Aircraft

The main driving force behind my current UAV experiments is lowering aircraft weight and noise. In principle though, this should not come at the expense of other factors, such as flying time, rigidity, responsiveness and crash-worthiness. So with these in mind, and after the eventual success of my last build, I’ve been planning for some

Flash & Burn, ESC edition

Many ESCs produce a high-pitched whining noise while running the motors. This is a result of the current switching that happens at the ESC. In many models, the frequency of switching is in the high audible range, and this translates to whining noise. If you’ve been following this blog for some time, you’d know that one of my
