In this project we’re building a cricket powered paddle wheel rover.
This simple water bot is 3d printed and features a tripod mount for capturing underwater photography.
The rover stays afloat with the help of pool noodles that are mounted to the 3d printed enclosure.
We used NinjaFlex filament to 3d print watertight mounts for the motors and components!
You can find the list of all parts used to make this project linked below!
We used MakeCode and programed our water bot to maneuver around obstacles. You can use the on-board sensors to make it interactive!
3D Printed Parts
These flexible motor mounts press fit together to help prevent water from getting into the components.
There's resources in these guides that go beyond what's covered in this tutorial. MakeCode guide is all about setting up your Circuit Playground Express board. TheCircuit Playground Express introduction guide walks you through all of the pinouts, sensors and everything you need to know.
We found the pool noodles have enough support for gopro session, but a slightly larger one like a GoPro hero should hold up. You can adjust the position of mini ball head to adapter for different water depths!
