Remote operated underwater vehicle (ROV) controlled by an Arduino and built from simple to obtain parts, plumbing pipe for the frame, drainage pipe for the main body, electric motors for thrusters. There is also an onboard camera to see what’s going on underwater.
We’ve got two micro ROVs in a tank that you can play with, powered by 3 small motors the model ROV can move in all directions and perform simple tasks lifting a small weight and moving it around etc.
Will also be displaying a robotic fish that can follow a light source!
