Lumos - Spotlight Drone

A GPS controlled Spotlight Drone

Once deployed, Lumos will hover above the designated area until its battery reserves are depleted at which point it will return to the base location and where it will be collected and recharged. The process will repeat until the units are no longer needed. To reduce interference with rescue operations it will fly at a distance of 200 to 300 feet above the area as to be out of audible hearing range and most physical obstacles.

    Bellow is Basic calculations of thrust for the RS1106 Motor and Prop Combo.

    The single 18650 or Dual 18650 will be boosted up to the Desired voltage using 2-3 XL6008E1 running in parrell to achieve desired voltage.

    Power of a single 18650 is ~9.25W (~ 3.7V * 2.5Ah)

    Power of a Dual 18650 is ~18.5W (~ 3.7V * 5.0Ah)

    The weigh of motor, 4x Servos, ESC, LED and 1x 18650 is 114g

    The weigh of motor, 4x Servos, ESC, LED and 1x 18650 is 159g

    Using the Below Thrust tables Optimal flight time Configuration

    1) Single cell 18650 Boosted to 8V 

    2) RS1106 (4500KV)

    3) GF3020 Blade

    4) 3.5A Current at 8V

    Assuming no efficiency losses Flight time could be ~ 19min

    Realistically flight time could be as high as 13min

Oh wow. I'm working on something very similar! Have you already had a prototype and made it fly?

  Are you sure? yes | no

John Loefler wrote 11/07/2019 at 22:50 point

Not at the moment, I have been looking into different motors

  Are you sure? yes | no

Benjamin Prescher wrote 11/07/2019 at 22:55 point

What kind of flight controller are you going to use here?

  Are you sure? yes | no

John Loefler wrote 11/07/2019 at 22:57 point

I am just looking into designing.  No flight controller has this configuration.  It would need to be developed.

  Are you sure? yes | no

Seems will you be able to set the correct height from the ground? GPS possibly? 

  Are you sure? yes | no

John Loefler wrote 09/13/2019 at 11:55 point

GPS is capable but I envisioned throwing it like a ball and it go to heigh while it waits to connect to GPS (about 15S) this can be done with a barometric pressure sensor which has a relative accuracy of +-1.5m

  Are you sure? yes | no
