First Autonomous Indoor Laps – No Tracklines!

Here for a quick update on the state of the car, platform and Tensorflow/Keras models I'm currently building and testing in various environments. I've been working on lately on an indoor model to drive a car around the dining table in our home. It is a simple oval track, but it is visually cluttered and quite tight. Here's a video…

Build an Autonomous Car with RPi, NAVIO2 and Tensorflow/Keras, Part II: The Software

In the previous post I've outlined the hardware build of a "Robocar", a simple autonomous car platform using monocular vision and Deep Learning, using a small RC car with few modifications. The post focused exclusively on the hardware. If you've followed the directions in that post, you should be able to customize your RC car with a simple wooden or plastic platform, a…

Indoor holonomic rover with NAVIO2 and Wifibroadcast

I've thrown together a quick mockup of a holonomic indoor rover using an F450 base plate, some CF tubes, a bunch of micro DC motors and my NAVIO2 setup, with a TL-WN722 wireless card. I've used the Fingertech Mecanum wheels, but I was quite disappointed at their design and build quality; long story short, I had to spend some time…

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 sure, and from an initial…

Intermission: NAVIO2 Arrives…

(Breaking the timeline of this blog and time-warping to the present for a bit) My NAVIO2 order has finally arrived from EMLID. This is really exciting news, and I can't wait to get started building with it and sharing my results. NAVIO2 is a really well designed PCB, both in terms of quality, as well as from an aesthetic standpoint.…
