This large video is about the project that Murray and me have being doing in the MAST Lab. It's about doing automatic position control and trajectory tracking of a micro unmanned aerial vehicle, being more specific is our 3D printed quadrotor platform,…Continue
PID loops can be pretty confusing when you're first getting started with autopilots.
Here's my attempt at explaining them "intuitively", i.e. with no math.
I'm working on plugging in a physics engine into the demo. Two more videos in this series are planned:
- Understanding the math behind PID controllers.
- Tuning PIDs…Continue
As my first blog post in diydrones I'd like to show, specially to other noobies what is the so much talked PID so much used in our Arducopters and Arduplanes.
This video has substitles also in english and russian but you have to select it to activate them.
It shows in a very dummy but effective way what PID is, and hope it makes things more clear for…Continue
Take a look at my heavy lift hexacopter.
It flies very stable with the standard PIDS.
Couldn't get loiter to work though.
NTM 910kv (changed to MK3638 on 4S)
Turnigy plush 30 amp ESC
UAP 1 frame
For booms i have 12mm kite tubes
5000mah 3S (now 4S)
Turnigy 9x + frsky
I use the hex to take aerials, with…
If you've been wanting to understand a bit more about PID controllers, unit 5 of Sebastian Thrun's Udacity course "Programming a Robotic Car" has some nice coverage of that topic and the theory behind it.…Continue
DISCLAIMER: This could be dangerous and might crash your copter.
OK! I made some new changes to the autotuning algorithm and I have tested it again in the simulator. I think this is ready for some real world testing from some VERY BRAVE users, or some simulation testing. Unfortunately I do not own a quad and my octo is out of commission until Tuesday, or I would be testing this right now outside.
Video of ROFL Tuning Session with spectacular crash when we deliberately detune one of the PID values! No quadcopters harmed (much) in the making of this video. Video of stable flight below.
By the way, the ROFL quadcopter kit is still on sale on my website:…Continue
Finally, someone has created a PID tunning howto video, from scratch to perfect stabilize flight, that I think will be very useful for the arducopter community, specially for those flying non stock frames.
The concepts are already in the AC2 PID tweaking guide developed by Jason, but a visual howto helps a lot!
The guide has been created by…Continue
