Auto mission with NicaDrone's EPM cargo gripper documentation

Hello all,

Cargo pickup / drop off in auto mission documentation using NicaDrone's EPM V3 and Pixhawk running APM :D

The OpenGrab EPM v3 (from NicaDrone.com) is a small (less than 4cm x 4cm x 2cm) Electro Permanent Magnet gripper capable of 200N of force meaning it can hold about 15kg of cargo securely. The gripping and releasing of the cargo is accomplished by delivering a short pulse to an electromagnet which reverses it’s field. Objects that it grips onto should be metal or have the included attached to them.
The device accepts a standard PWM servo input or UAVCAN and uses a 5V power supply. Significant amounts of power are only required for about 1 second when it first grips or releases the cargo.

    @Andreas

    I think Tom has already answered, this isn't about rivalry, it is about someone spreading lies. And I'm sure you understand that it is serious, not something we laugh at.

    And yes, we should go back to development talk and user support - it is just really sad that someone is trying to get people away from us by spreading lies, instead of trying to be better. And maybe that's the issue, they aren't able to be better.

    Yeab,..hmm....

    Your right I spoke in error. Please accept my apologies. Can we delete the comment(s)?

    Shall we get back to the task at hand and do user support?

    Auto pilot rivalry includes saying Ardupilot firmware has been depreciated and development will stop? That is not rivalry. That is... something else. You say you don't know enough to form an opinion which means someone simply told you. Who is spreading this outright lie?

    @ Fransicsco, 

    There seems to be some healthy rivalry between the PX4 and APM teams! 

    Point taken thanks

    @Andreas

    May we know who told you such a thing?

    If you are going with user demand, there's no doubt that you should focus on ArduPilot.

    APM firmeare; 

    Hahahahahaha, maybe I was misinformed :D Anways I am don't know enough to have an opinion 

    I'd still prefer to focus on the PX4 depending on user demand 

    @Anthony chat me up on skype; Andreas Jochum / Nicadrone and we'll have a chat with Pavel. And we'll post a pull request if we cock up something useful :D

    Andreas probably meant the APM autopilot which is not supported anymore since 3.2 and refers to using Pixhawk instead

    Andreas, I don't know where you are hearing that information but it is nonsense.  ArduPilot has more companies and more developers involved than ever before. http://ardupilot.org/copter/docs/common-partners.html

    Woah, where did you hear that? We're more active than ever! Averaging 400 commits/month at the current rate.

    APM is about to be deprecated and development will stop. 

    I think we should focus on PX4, what your thought Anthony?
