Our technical documantary report. Here, you can find everything about our design, electrics, coding and so on.
The picture shows our final robot. With this version we are qualified for the competition and we participated.
The aqua noodle we use as an uplift force and it is edge-mounted, is missing.
More features are:
- a grappler which we can manually spin up to 90 degrees
- a hose with whom we can blow up under water the liftbag
- vectorial orderd motors which promise a better stability
These are our four engine control units. One navigates two engines (reconstructed Bilge-Pumps).
The bronze caps are passive cooler, so that our technics won't over heat.
A small glimbse in our compartment which still looks cleaned up, because it's not wired yet.
For safety and for practical reasons we mounted the electrical parts on a black acryl slab which is removable.
Under it there is still some space for silika-packages, so that everything will stay dry despite moisture.
Here you can see for the first time our future ROV. Missing is the most important thing: the HARDWARE!
The hardware (RaspberryPi, camera, ...) will be placed in the transparent compartment and thorugh the back pane which is extra waterproof. After that the wires will be pooled in a tether with a safety line and transfered with a strain relief system to the robot.
The tightness of the compartment will be ensured then by pressure by a seal ring made of gummi and a neofermit-paste through pressing them on the out pane.
Moreover, you can see the sealed grapper to solve the MATE tasks.
Our IT-Management (Mikka)works hardly to navigate the ROV with a PS4 Controller.
That is why the controller and the engine (located next to the rectangle with numbers on it) are conected to a Raspberrry Pi.
You can see on the picture a laptop, a solderin station, an engine, a transformer, a reel of solder, a PS4 Controller, a Raspberry Pi and a bluetooth music box, which actually does not belong to our project.
After we meticulously measured the dimensions of the compartments, we started with designing a construction blueprint.
Afterwards Florian, Jan and Jannis (from left to right) converted our blueprint on the panels.
Jannis sawed it hyper-accurately out and Florian gave the panels with sandpaper the finishing touch.
Jannis assembled at the teacher's desk the devices and cecks again if the compartment fits like we wanted to.
Similary, we worked on the connection between the compartment and the shell, so that we could place the hull of the ROV brain in the best way at the frame.
Without a waterproof container and its content our robot would be useless. Moreover, the camera and the gripper arm are controlled by the Raspberry Pi such as the engines.
