Hi folks!
I’m planning to make a simple and very cheap ROVs to do some experiments with thrusters (homemade), pressure sensors, IMU, underwater vision with simple RGB camera.
I have experience with ROS, my question is about the hardware design.
I didn’t want to use a raspberry, but a tethered communication with my PC to send all the sensors data (I don’t care about some latency).
To manage all the sensors feedback and the thrusters signals I was planning to use a simple Arduino, with the proper shield and DC/DC to control the high-voltage thrusters DC motors.
For the frame structure I was thinking about the simple SeaPerch design.
My question is about how to build a waterproof case with all the electronics , and also the waterproof cabled connection from PC to the robot brain (the Arduino).
I know that often the overall electronics is surrounded by gel, inside of a insulated case, how can I create such a case?
The SeaPerch project is a simple ROVs used only for teleoperation.
What I want to add is the simple sensors to get some feedback, visualize the robot state in Rviz using simple IMU and Pressure odometry, and get monocular camera feedback, maybe to perform some simple object classification during dive.
Anyone has some advice or know some useful blog related to DIY underwater robot design?
I don’t even know if my simple project is feasible with this simple design choice, expecially in terms of electronics and communication (I might be good with ROS and RoboticsTheory but a principiant with electronics).
Thank you all for your help and advices!
