Disabled veteran with a patent pending drone system needs YOUR help please.

I hope some of you will help me, I see many posts where nobody gets help or advice. I am putting together a prototype quad for a system i am developing for law enforcement. I have been desig ing for a long time and its time to compile a list of components. With all the choices out there i am hoping you can assist me in narrowing the field. I am trying to achieve a functioning drone for as much flight time as possible. I need an array of sensors to help create a semi autonomous aircraft which is only a part of the system I am creating at the end of the campaign. To get more investors I need a functional physical prototype. Prove the concept is my goal. I am a disabled veteran , I was a mechanic and pilot of helicopters and have had many r/c airplanes over the years but this is more complex. Anyone help me start with a list of hardware to start buying so I can assemble a drone that is upgradable? I am looking at a max weight with flir and 4K camera combo of around 2-2.5 kg. Thanks in advance everyone.

If you want to compare several configurations you can use this site : https://www.ecalc.ch/xcoptercalc.php

It will give you some info about flight time regarding motor, battery, propeller...

3520 T-Motors and 5000mAh 6s battery with 13'' propellers should be a good entry point

I knew about calc, my needs are. From scratch, what systems should I get, if I want video links what RX tx should I get, what sensors should I get, ect...

Their are plenty of Tx/Rx video system available, it only depends on range (and cost) you are expecting but also on quality and reliability. Some inputs you have to take into account :

  • HD video = high quality, some delay in transmission VS Analogic Video = lower quality, low delay, high reliability
  • 1.2GHz have a better range than commonly used 5.8GHz

Once again it depends on your constraints of your application

Before choose sensor, you have to explain what you are expecting by 'semi autonomous' :

Automatic flight path based on Waypoint and GPS? (if so go with Pixhawk 2 or 3 and Mission Planner Software)  You will be able to add sensor for altitude control (lidar lite for example). also you can add some basic Obstacle Avoidance features

If you are looking for a platform able to perform advanced OA features, you have to bring up a Companion Board in parallel of your Flight Control to process data from Camera or 3D Lidar sensor http://ardupilot.org/dev/docs/companion-computers.html

Once again, without informations on your applications, i can't go further in helping you

Sensors depend on flight controller , integration also depend on flight controller, video and telemetry systems also can depend on flight controller you need to choose FC, then Arial platform copter, airplane, or VOLT craft .  what is your patent pending system ?

That is interesting,  a companion computer is something I hadn't thought about. If I choose the pixhawk 2.1 and install the arduino board, will I still need  a companion, like a rasberry ?

Without an NDA I can't get into specifics

Why you want to install Arduino in addition to Pixhawk ? 

Caricaturing : Pixhawk is actually an Arduino, with low level capabilities for flight stabilization, but also supports high level commands through MAVLINK http://ardupilot.org/planner/docs/common-mavlink-mission-command-me...

With a Companion Board, like a RPi, you have a real computer running a Linux OS with all corresponding features

See, I need to know these things I thought arduino was a microcontroller and you need a different flight controller,  THIS is why I need you all.

You are right about Arduino : Both Arduino and Pixhawk/APM are based on microController

Although companion boards such as RPi are based on microProcessor

So...is arduino with raspberry better than pixhawk and raspberry and do I need to be a coder to work either?

The best combo and widely used is Pixhawk with Raspberry Pi as described here http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

'I need to be a coder to work either' --> You will need at least to understand linux commands. And depending on your application, code your own scripts

Awesome. I appreciate any and all advice, I have an engineer that can do the programming I just need to know the best hardware for him.
