Step 1: Assembling the drone suite Once all components are obtained, start assembling the drone: put the black frame together and put the electric motor on top. Use some tape to secure the ESC (Electronic Speed Controller) to the frame and connect them to the motor. Place the ESC's power (red) and ground (black) end in a single cable (later connected to the battery), then secure all parts under the frame. Adjust the power module connector to the battery connector. There are several ways to do this, but there is a quick way: cutting the connector, welding the battery and power modules together. Turn off the other end of the power module and then refold the battery connector (previously cut). Finish! This will enable us to easily connect "Battery + Power Module" to the drone. Putting the Battery + Power Module Pack below and completes using the dimensional riders contained in the package.
Step 2: Prepare the automatic driver as shown below, connect the PXFMINI shield to the top of the Raspberry Pi Zero:
PXFMINI (Represents Pixhawk Fire Cape Mini) is an automatic driver shroud for the Raspberry Pis. It is used to build robots and drones. You have already completed it, but you still need to get the right software on the Raspberry Pi Zero + PXFMINI kit. This should include a flight stack, an appropriate kernel, which is enabled to start the daemon and other advantages when starting.
Fortunately, if you purchase PXFMINI from Erle Robotics, you can access the Debian image containing all of these content, so you can simply get the debian image compatible with PXFMINI and flash it into the MicroSD card.
Step 3: Install the automatic driver
PXFMINI is mounted in a raspberry zero assembly to install automatic driver (Raspberry Pi Zero + PXFMIN) on the drone. Take you and connect the JST GH cable from the power module to PXFMINI. After connecting the battery, this will supply power to the automatic driver. Next is to install the PWM channel in the automatic driver. Take the ESC cable, then connect the ESC 1 (corresponding to the motor 1) to the PWM channel 1, connect the ESC 2 to the PWM 2, and so on.
Step 4: Install the propeller and make it fly! There are two propellers in clockwise (labeled "R") and counterclockwise. The propeller in the clockwise direction is placed in the motor 3 and 4, and the propeller in the counterclockwise direction is placed in the motor 1 and 2. Finally, you need a way to control drones. I propose a few ways: WiFi + Game Handle: Let the Automotive Driver creates its own WiFi network using a USB software (Erle Robotics image supports this feature) and uses the general game path to control drones through the ground control station. WiFi + Ros: Do you know the robot operating system (ROS)? You can use the ROS node to visualize flight mode, status and control drones. Traditional RC: You can also purchase an RC controller with a receiver that enables PPMSum, and connect it to an automatic driver (connected to the PPM-SUM input channel).
