Other electrical components and sensors

Power supply

Powerbank 27000mah to supply 5V for micro-controllers and 12V to the DC motors
GELRHONR USB C PD Trigger Board Module to use power bank as 12V supplier
90 Degree USB C Extension Cable Male to Male
90 degree USB A to USB type C male

GPS sensor with antenna
Xiao RP2040 as main micro controller

Remark: the GPS sensor also comes with a cable that supports VCC, GND, RX and TX. This cable needs to be adjusted later on

Main controller (alias brain)

ESP32S3 as wifi server and central brain
Grove Vision AI module v2 for object recognizion.

Remark: The AI module v2 comes with a Grove cable that supports power and I2C. This cable needs to be adjusted later on

Camera module
Ribbon extension 300mm cable for camera to attach the camera all the way throught the duck to inside the platform/ hull

Waterjet pump

2x High Efficiency 380 Motor Water Jet Pump 6-12V Spray Propeller Accessories for RC Boats Remote Control, Black/White (Black)

If not already included then you need two DC motors as well

2x Micro Motor DC 12V 10,000 RPM 2.3mm

Magnets

8x3mm Powerful Neodymium Magnet N35 NdfeB Permanent Magnetic imanes Round Super Strong Fridge Magnets DIY

Sealing of 3D prints

To make the 3D prints water- and gas proof I used Dichtol It's safety sheet.

Note

According to the instructions it can fill holes between 0 and 0.2mm. I have printed with 0.25mm. SO DOES THIS WORK???

Software

2D/3D modelling

Install the latest stable version of Solvespace to read/edit my 3D platform designs
Use (browser-based) draw.io to edit the C4-models. To enable the C4 shape library click more shapes in the left panel, select the C4 shape library in the Software section, then click Apply.

Programming

I programmed in C using Arduino IDE (for the Xiao ESP32S3) and Visual Studio Code (for the Xiao RP2040)

Arduino IDE

Install Arduino IDE version: 2.3.8
Install the following libraries:
- Async TCP enabling trouble-free, multi-connection network environment for Espressif's ESP32 MCUs.
- EPA Async webserver to enable an asynchronous HTTP and WebSocket Server
- SeeedStudio SSCMA to communicate with sensors equipped with the SSCMA-Micro firmware
Install board manager for ESP32S3

Visual Studio Code

Install Visual Studio Code
Follow the instructions from SeeedStudio to install PlatformIO
Edit platform.ini
