PATROL FISH TO COLLECT AND CHECK THE CONTAMINATION OF A WATER BODY

Robotic fish is a biomimicking of a real-world fish being developed with a view to enable surface level cleaning of water bodies.

Introduction

Robotic fish is a biomimicking of a real-world fish being developed with a view to enable surface level cleaning of water bodies. The fish monitors the pH levels of the water that it is currently in. The fish has to perform the above two tasks yet exhibit a good stabilization. To establish a stabilized structure of the fish the right buoyancy and a low center of volume and mass has to be ensured. To bring in locomotion against the currents of the water and to enable enough propulsion to push forward the garbage collected requires the fish to produce adequate thrust. To transfer commands to the fish from the operator a suitable communication mechanism, a web socket accompanied by a web application on the transmitter side and a ESP32 on the receiving side enables one to send control signals which would in turn enable locomotion and surface level cleaning. To avoid any damage to the circuitry a suitable water proofing mechanism is adopted.

Objectives

  • To plot the x, y and z co-ordinates.
  • To estimate and visualize the 3D orbits of the GPS satellites using GPS navigation file from GNSS receiver.
  • To analyze the GPS satellite orbit.

Methodology

The implementation of the robotic fish is based majorly on the   design which in turn relies on the concept of buoyancy and a low center of mass. Keeping the kinematics of the fish and the structure required to clean the water surface level, the design phase is conducted. The kinematics analysis relies on the links and the number of actuators going to be used in the design to enable a good locomotion in water. 

To transfer commands to the fish from the operator a suitable communication mechanism, a web socket accompanied by a web application on the transmitter side and a Arduino NANO on the receiving side enables one to send control signals which would in turn enable locomotion and surface level cleaning. To avoid any damage to the circuitry a suitable water proofing mechanism is adopted. With a view to accomplish the above stated objectives in developing a bio-inspired robotic fish the below review was conducted.

Results

           A robotic fish with suitable cleaning structure mechanism controlled over joystick and a Ph sensor would help in the surface level cleaning and checking the contamination of the water body continuously.
