Build Smart Drone For Pandemic Time

Drone technology has evolved very much as is much more accessible to us than before. Today we can build a drone very easily and can be autonomous and can be controlled from any where of the world

Drone Technology can change our daily lives. Delivery drones can deliver packages very fast by the means of air.

We can build similar kind of drone.

How Drone in a Box Solution Works?

Note: This Project is in Work-In-Progress and will be heavily modified on later versions

My apologies for only 3D rendered photos since was unable to finish to build the drone due to supply shortages during the Covid-19 Pandemic.

For this project we will require the bundle containing these items-

You can use The HoverGames drone kit

• HoverGames drone development kit components include:Flight Management Unit: RDDRONE-FMUK66FMUDC-to-DC power moduleGPS: GPS NEO-M8N module with mount, Safety switch, Buzzer, and bright RGB status LEDDebugger: SEGGER J-Link EDU Mini / FTDi USB-TTL-3V3 cable / Debug breakout board with cablePlastic enclosure and stickerBLDC brushless motors 2212 920 kVESCs motor controllers 40 A OPTOPropellers 9450 self-lockingRC remote control: Touchscreen FS-i6S transmitter and FS-iA6B 10 channel RC receiver with IBUSMiscellanous cables, screws, and tools

The HoverGames drone kit is a single, modular, and flexible NXP development platform with the RDDRONE-FMUK66 flight management unit at its base. It can be used to build any autonomous vehicle, from drones to rovers to flying cars. As part of the kit, participants receive a complete reference drone including the flight management unit (FMU).NXP HoverGames drone kit including RDDRONE-FMUK66 and peripherals

Wiring the Pixhawk

Helpful link for first time set up>> https://ardupilot.org/plane/docs/arduplane-setup.h...

After finishing the first time setup connect the ESC of the motor to pixhawk and other servos for the control surfaces to pixhawk then configure them one by one in the Ardupilot software(https://ardupilot.org/plane/docs/plane-configurati...)

i'm using Pixhawk kit for making this

Autonomous Control Over 4G and FlytOS

. The Pixhawk 4, which has several different wires and connections with it. Included below is a picture of every wire needed with the Pixhawk and how it looks when connected.

Plugin Telemetry and GPS module to the flight controller as seen in Figure 20; plug in the RC receiver, all 4 ESCs to the flight controller as well as the power module as shown in Figure 21.

After finishing wiring our flight controller with the system we will start building the Autonomous Control system

This can be achieved by using Raspberry pi with a 4G dongle and a PiCam to receive the footage

The Raspberry pi communicates with the Pixhawk flight controller using a protocol known as MAVLink

For this project I am using Raspberry pi 3

Setting up raspberry Pi 3

• First download FlytOS image from their Site by Registering yourself and going to downloads tab-

https://flytbase.com/flytos/

• then create a bootable media using Balena etcher and the plug it in to raspberry pi.
• After booting flytOS contect to your LAN cable and then go to this link in your PC browser

http://ip-address-of-device/flytconsole

in the "ip address of device" type your rasp pi ip adress

• Then activate your licence(personal, trial or commercial)
• then activate rasp pi

Fully assembled, the kit looks as shown below:

Now Configuring in your PC

• Install QGC(QGroundControl) on your local machine.
• Connect Pixhawk to QGC using the USB port at the side of Pixhawk.
• Install the latest stable PX4 release in Pixhawk using QGC by following this guide.
• Once done, visit parameter widget in QGC and search for parameter SYS_COMPANION and set it to 921600. This would enable communication between FlytOS running on Raspberry Pi 3 and Pixhawk.

You will need to select the Holybro S500 airframe (Quadrotor x > Holybro S500).

Then perform the mandatory setup/calibration:

• Sensor Orientation
• Compass
• Accelerometer
• Level Horizon Calibration
• Radio Setup
• Flight Modes

Ideally you should also do:

• ESC Calibration
• Battery

Delivery Drop Mechanism

The Delivery bay door is controlled by servo motors. They are configured in the autopilot software as servo

and they open and close when the aircraft reaches the delivery waypoint

When the aircraft reaches delivery waypoint it opens its cargo bay and drops the delivery package which land gently to the delivery point with the help of a paper parachute attached to it.

After delivering the package the drone will return to its base
