You can purchase it from amazon.de (search for 'propeller 10x4.7' in the search box). Apart from that you can buy it from hobbyking.com (EU warehouse), www.buildyourowndrone.co.uk (same as Arducopter props) are available there. Ebay.nl or ebay.co.uk are also good options, btw!
You do not need to order it from 3DRobotics, USA (it is way too expensive from there, esp. due to shipping). I never order small parts from them. For screws, other hardware items I order from farnell or hobbytronics.co.uk
Hi Shyam, I'm a drone sw developer, currently working on updates to the px4 firmware and qgroundcontrol (among other things).
I wonder if you've come across any academic projects involving precision multirotor landing and takeoff? What I'm looking for is tech that will essentially allow a multirotor to land in a box not much bigger than itself. If you think of anything, let me know. Thanks!
Thanks Shyam for your comments. Here are some flow diagrams of (stabilize)/(altitude hold) modes. I have downloaded them earlier but they will give you a good idea about the controller. Hope this will provide you a kick start to understand the basic working of PID controllers. Please find the flow diagrams of the controllers attached!.
1) I want to import all sensor data of apm board (gps, magnetometer...) to matlab/simulink and send trajectory data(a set of 3 axis coordinates of target nodes in order) 2) I want to get speed transfer function of motors real time in order to get PID parameters via matlab/simulink(i know that we can tune PID parameters via mission planner soft. but i want to learn about this method)
Which method is useful for the purposes above:
-mission planner soft-matlab connection via serial port
-apm 2.6 and arduimo ide connection via xbee-usb and then arduino ide and matlab connection via serial port. Thank you.
Greetings sir Shyam! I saw your MAVLINK TUTORIAL FOR DUMMYS on diydrones.com, and it was incredibly helpful! I would really like to thank you for such enlightenment. I'm currently working on PIXHAWK and Mission Planner, and I'm required to obtain the real-time x-y-z, roll-pitch-yaw, altitude etc etc...
I'm still new to this research, and I was wondering if I could ask a couple of things (to be honest, this would seem like dummy questions but I'm a little desperate, so any form of help would be highly appreciated):
1. Where can I locate the GCS_Mavlink.pde and the Arducopter.pde files? I can't seem to find it anywhere on the Mission Planner Program Files folder, so I couldn't see what was inside? Or am I still missing something? (Because so far all I've done is calibrated my PixHawk and installed it with the firmware using Mission Planner)
2. Is it possible for me to use these data to be taken as input to MATLAB as variables?
I just want to clarify some of the things that I'm trying to achieve. I'm trying to implement a Sliding Mode Control (Dynamic Control) of a quadrotor using PixHawk, and for now, I'm trying to obtain the sensor values for the dynamic control (as I mentioned before, attitude and altitude). So I would just like to ask some few more dummy questions...
so I've watched a lot of videos concerning the ardupilot stack and Mission Planner, although I don't completely understand how they are related.. I'm not quite sure how to use them together.. The problem I had with Mission Planner is that it doesn't give me the real-time values of those sensor values as they are what I am after.. I have found many solutions making use of a modified version of Arduino for working with the pixhawk without mission planner... although I'm just looking to obtain real-time data from the pixhawk and maybe process them in arduino or matlab... so I would just like to ask some fewer more things:
1. With the modified version of Ardupilot Arduino, would I be able to implement commands for motor speed control using the parameter values I obtained? And would this make the Mission Planner basically useless at this point(besides from GPS navigation)?
2. Or is there a way for me to meddle with the mission planner codes to obtain these values and implement my own control?
I'm sorry if I ask too many questions, but I'm REALLY APPRECIATIVE of your helpfulness and quick responses, so thanks again!
