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! |

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. |
