Automatic underwater Arduino based patrol system with WiFi controller.

 

Our robot guard goes along a long fishing line. On the edges of the line are attached magnets and the robot has two Hall sensors. Thus, the robot moves from the magnet to the magnet. Algorithm and speed of movement is programmed through Arduino.

In order for our robot to be recharged directly under water we used two large inductors. One is installed at the top of the robot, the second is on the underwater base. They work well even in salt water and give a charge current of 0.8-0.4 Ampere at a distance of 1-2 inches.

The hull made of a thick-walled PVC pipe so that our robot could withstand a lot of pressure. The edges of the pipe are covered with lids with o-rings. Inside the pipe there are 3x18650 batteries, Arduino with a WiFi module and a motor speed controller. The wires for the motor, Hall sensors and inductor are fused through the pipe wall. The robot body also has additional outputs for powering and controlling the external flashlight and camera.

The WIFI antenna is connected to the metal guide rings. When the robot arrives at the base, the ring touches the antenna wire, which rises to the surface. Thanks to this, we can control the robot directly under water.

We used one of the best thruster. At just 0.5 Ampere it gives incredible thrust of 1.1 pound. That means it can go at 3 miles per hour with a big underwater camera for 6 hours without recharging. Or, for example, it can range 660 feet in 3 minutes, and then fully recharge in 5 minutes.
