Teraranger not detected on Pixhawk/Arducopter

Started this discussion. Last reply by Mike Isted Jun 11. 1 Reply

I have recently purchased a Teraranger One with the i2c adapter cable.  It's all wired up and configured, but the sonar range on the Mission Planner flight display simply reads 0.Here are the things…Continue

"Hi All Apologies for my absence.  I have had to take a month out of the project, but now can get back into it. I have got as far as successfully sending some limited commands from a C++ program to the PixHawk (rather than from the command…"

"Hi Nicolas I see what you mean.  I have a little longer and will try and build on the other tutorial at http://qgroundcontrol.org/dev/mavlink_linux_integration_tutorial. I am also interested in integrating OpenCV at some stage, but that I think…"

"Hi Sergey It may be the answer lies with the instructions here: http://www.qgroundcontrol.org/dev/mavlink_onboard_integration_tutorial With this, it should be possible to build some software on the Pi to directly send Mavlink commands.  The Pi…"

"Hi Peluzza I see your point, but I am taking the same approach of using a PxH and Pi together.  Partly this is to keep the overall system modular and partly because I prefer to adapt the APM code as little as possible - it's quite complex…"

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.

Groundhog Autonomous UAV - Going faster with sunglasses

Posted on May 22, 2017 at 3:00pm 0 Comments

The Groundhog is being developed to line-follow at low altitude and higher speeds.  This video is of the field testing taking the speed up to 1.75 m/s.  It also explains why the Groundhog now sports sunglasses.

It's been a few week since tests were conducted of The Groundhog line-following a straight red line.  The Groundhog was an entry in the MAAXX Europe 2017 competition and although it didn't win, the lessons learned are being implemented so that it can be more competitive next year.

Time and…

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…
