Microcontroller
Microcomputer
Raspberry Pi 4 Model B
A low cost, pocket-sized computer with processing powers similar to economic-grade laptops, it is a widely used microcomputer utilized in many small-scale projects.
Typically using a Linux-based operating system known as ‘Raspbian’, it is capable of running several coding languages such as; Python, JavaScript, Scratch & etc. With control General-Purpose Input/Output (GPIO) pins on the Raspberry Pi, it uses your preferred coding language to control electronic components such as displays, sensors & more.

Automation
Pixhawk 2.4.8
Flight controller utilized in autonomous system projects.
If you are someone who is interested in learning to utilise Flight controllers such as this, I highly recommend reading up on Firmwares available (eg. Ardupilot, PX4 Flight Stack, BetaFlight). We recommend Ardupilot as it is the most well-documented and loved in the RC community. Thoroughly read through the documentation and carefully plan the type of Motors, Telemetry and Ground Control Stations (GCS) you will be using. Good luck! You’d need it. 💪

Digging Mechanism
CNC Z Axis Slide Table 50mm + NEMA17 Stepper Motor
The slide table uses the NEMA17 stepper motor, which is a brushless DC motor that is able to break down the rotations into steps, allowing for precise movement of the slider.
A4988 Stepper Motor Driver Module
The A4988 Stepper Motor Driver Module acts as the logic for the NEMA17 stepper motor. Input controls from RPi are converted to outputs that control the electromagnetic coils in the Stepper motor to finely tune its direction and steps.

MG995 Metal 360 Continuous Servo
Servo motors allow for precise control over attached components, such as angular/linear positions and acceleration.
The Continuous Rotation Servo can turn in a Clockwise or Counter-Clockwise direction. Turning speed and direction is determined by the pulse width modulation (PWM) signals, in other words, the length of the pulse.

Micro Submersible Water Pump DC 3V-5V (Amphibious Type)
Power System
3300mAh 3S 30C LiPo Battery
Even electronics need to ‘eat’. Be careful when using lithium-ion polymer(LiPo) batteries! These things can start a fire really easily.
XL4005 5A Buck Converter
A DC to DC power converter utilized to step down voltage from the input to an appropriate level on the output for its load. This is used for both creating appropriate voltage levels for components and reducing average drawn current.
Motor Driver
Mini 20A ESC
A brushed ESC, it controls and regulates electric motors through pulse width modulation (PWM) signals, allowing for forward movement, reverse movement and dynamic breaking.
Typically consisting of a microcontroller & H-bridge, the firmware installed within the microcontroller interprets input signals from the Pixhawk or RC receivers and outputs the PWM signals to the brushed DC motors for movement.
