GPS Racer: worklog #9 – double rangefinder setup

My GPS Racer is less and less fun project. For last few weeks it acts as sensor platform for my attempts to bring rangefinders and terrain following modes back to INAV. This time in a way that will work.

Two weeks ago it was carrying HC-SR04 sonar (crappy device). Week ago it was carrying US-100 (much better device). This week it is carrying both US-100 sonar and VL53L0X lidar!

DigitalEntity apparently had too much spare time and he finally wrote (ported) a driver for VL53L0X and starting from version 1.8 (probably) INAV will be able to use this cheap lidar.

Yes, VL53L0X is cheap and that means it's not state-of-the art device. First of all, it has limited range. 2m is all it can do in a room. No idea how it will behave in sunlight. Hard to guess, but I'm afraid that 1m will be all it will able to do in real life conditions… But we will see in a next few days.

  1. I’m going to invest in a coupla these VL53LOX devices. looking at the spec sheet, i’m wondering if you’re going to use “continuous” or “timed” data collection or using an interrupt. also, i agree with your skepticism regarding outdoor accuracy. I’m hoping your testing will bear fruit, in the meantime, i’ll be testing these puppies out, indoors.
    keep up the great work!
