"Hi Mike!  This is so interesting that I feel like implementing it at home in my free time.  Do you have any videos? Will be good to see your drone in action :) "

Mike Isted replied to Khushal B's discussion Line follower project using a machine learning approach on Raspberry Pi and Pixhawk
"I think channel overrides are seen as an easy and effective way to do it - they also work indoors, so they work if you don't have gps.  Yes, Dronekit does mention they don't want to use them... So I think your choices are: 1. Channel…"

"This is exactly what the MAAXX Europe competition is about.  My blog on this starts here and links to other resources to hook up a RPi 3 to a Pixhawk, using Dronekit and Python. Hope it helps :-)"

Post 5. MAAXX Europe. Quaternions, control code and PIDs.

In this last post of the series I shall overview the main program including the control algorithms for the Groundhog.  Code is written in Python, using Dronekit and OpenCV all running on a Raspberry Pi 3.As we are flying indoors without GPS and also without optical flow, we are using quaternions to control the…See More

Mike Isted commented on Mike Isted's blog post Post 4. MAAXX Europe. Connecting the Pi 3 to the Pixhawk
"I posted this some while ago when I was using a Pi2 myself. Fig 18 shows the code segment.  Of course you do not need to worry about the bluetooth with a Pi2. I switched to a Pi3 using Dronekit to try to simply things somewhat.  With…"

"thanx for this guide since most people find connecting pi with pixhawk challenging despite lot of support on ardupilot.org and that's is specially true with Pi3. great you highlighted the disabling of Bluetooth on Pi3. I am using Pi2 but still…"

Post 4. MAAXX Europe. Connecting the Pi 3 to the Pixhawk

In this short blog series I'm outlining the hardware and software of The Groundhog, my entry into the recent MAAXX-Europe autonomous drone competition held at the University of the West of England, Bristol.Connecting the Raspberry Pi 3 to the Pixhawk took quite some working out, so I am hoping that by publishing…See More

"Hi Chris, I thought I'd looked at everything line following on YouTube, but this came on later than the competition.  It looks awesome!  Far more sophisticated than my efforts! I'll take a closer look and many thanks. …"

"Great post. This is almost exactly what we do with our ground rovers, using the same basic tools (OpenCV and RasPi). You can see some samples here and here.  You might also want to check out the OpenMV cam, which does the same…"

Profile Information

About Me:
A specialist in digital education supporting schools in Powys, Wales. In whatever spare time I have between job, family and house, I develop my UAV platform to do challenging things autonomously.

My first degree is in Physics and Computer Science and I am currently enrolled with the Bristol Robotics Laboratory on a Masters by Research in Robotics.
Please tell us a bit about your UAV interest
I was bought up with RC cars and worked on embedded systems in my early IT career. I have always been a proponent of the make revolution and the democratisation of technology. Having children reintroduced me into the world of UAV and I haven't looked back.

My interest is primarily around autonomous control augmenting ground based humanitarian activities. However I have quickly learned that once you go beyond gps 'point and shoot' control, it gets a whole lot more interesting. And that's where my interest lies, just outside of the standard flying envelope, so to speak.
