  • You should say that the NCR20700A cell at 20A has his capacity down to 2800mAh

    and the rated 3300mAh capacity is only for 0.5A load.

    These cells are not for heavy UAV but for ultra efficient UAV, it is a different thing.

  • Cristian , I have work with Li-on batteries and I do not completely agree to what you wrote about.

    - These are not "real" 6S packs since the maximum tension of Li-on battery is not the same of Lipo batteries, look at the graph belòw , the blue line fit best scenario.

    - The pack capacity in real world is not 21Ah , looking at the datasheet by Panasonic it is quite clear that the usuable capacity correspond to voltage low as 3 volts, so lets say 3100mAh if you have 1C discharge rate, blue line.

    3702367359?profile=originalThese type of batteries can be used on drones with very high efficiency and low Ampère draw, should be around 1C during hovering so 2C during normal flight.

    I have done some maths , and the example you gave with 70' flight 5kg AUW works only with a quad with 26" propellers and a 1200 grams payload.

    Copters with "normal" props around 15-17" will raise the Ampère drawn and make these batteries type more and more difficult to use because of their maximum 3.1 C rate of discharge.

    As you, we are passionate about drones and agricultural applications. At the moment, we have developed a low-cost camera that would let you know about health of plants and crops through NDVI multispectral analysis.  The good news is that we will launch it by a crowdfunding project in Kickstarter. Here there are the main features of uSense camera.

    To drive our product to the right market we would like to know your comments and thoughts regarding the next questions:

     

      1. Type of uses that you will do it with a camera like that.

     2. What are the features that you will love add it?

     3. How much you will be willing to pay?

     

    Thank you for your comments, we appreciate the time and any link that you think could help us as well.

     

    If you want to know more, don't hesitate to contact us!

    Cheers,

  • Hi Silvio

    I used a My Fly Dream flight controller.
    I am based in the UK.
    I  was involved with RC airships 20 years ago  and have recently returned to it to  develop an update electric powered system that would be practical and affordable for commercial and leisure market, using off the shelf drone components etc.
    regards
    Martin
  • @Martin Hill Compliments, your LED is amazing! What flight controller do you use? we're super interested in testing that vehicle with VOLTA 4Gmetry (http://diydrones.com/group/volta) - write me silvio@voltarobots.com and we will arrange something for sure! Once again, it's one of the most interesting projects I've seen here!

    If anyone is interested, I'll process some imagery for you using Pix4d. I'm not setting out to be a data processor, but I'm spending a lot of time in the program and just finished setting up a new server for processing our images. 

    The weather is crap right now and I'm tired of playing with the same old data sets. If you have some you'd like to share, upload the unedited files to drive/dropbox and PM me the link.

Open Source Drone Payload Project Supporting In-Flight AI

I'm leading a project to develop a completely open source system for deploying artificial intelligence and computer vision on a drone. We are trying to make the system as general purpose as possible, but one application would be supporting precision agricultural. The real-time, in-flight processing aspects of the payload are probably less interesting for precision AG, but the data collection and curation capabilities might be. We are getting started with a few specific missions, we are…

Ground Station for Spraying Drone

We need a GSC for a small spraying drone base on Pixhawk. It should be capable of pausing the mission whenever the tank is empty, return to launch, and after refueling or changing the battery, return to the last waypoint that the mission was paused and continue the mission. The GCS should run on android and be swarm cable (at least in the future). Could this be done in Qgroundcontroll or should I consider doing it using DroneKit or FlytOS on a companion computer? Or is there any other…
