Objective: Design and Development of an Autonomous Mobile Robot for the River Health Monitoring Sensing System.

Research Outline:

  1. Many remotely operated stationary observatories have been developed world-wide for river health monitoring application.
  2. These stationary platforms, although are quite successful in analyzing and transmitting water quality data of the main river channel, they are unable to collect the same information from the tributaries close to the main channel of the river.
  3. On the other hand, rivers like Ganges are known to be very much susceptible to pollution from the secondary channels.
  4. A Design concept generated to counter such situation is to develop an array of mobile floating robots which can move from the main station to the tributaries, collect the water quality data and transport them through a wire-less transmission system to the main aquatic observatory.
  5. The following are the major challenges envisaged to develop such a system.  
  • The over-all weight of the robot should be as low as possible to increase power efficiency.
  • A Combination of Composite Pontoon along with open truss system will be designed towards this direction.
  • The system should be highly mobile and hence bi-modal power development (hydro and solar) is considered.
  • To harvest the water power, the energy harvester that will be developed in the Work-package seven will be customized for the mobile robot. Also, the solar power will be used to supplement the power requirement.
  • The entire system will be integrated with six essential water quality sensors which will be housed inside the two shells. Based on the capacity of the wireless-sensor system, the coverage of the
    robot is envisaged to be within 1Okm range from the stationary platform.
  • The robot will be equipped with map recording and self-guidance controller to position it suitably from the sensing point of view.
  • The sensor data will be both recorded in a data logger as well as an excerpt of the data will be transmitted through the wire-less sensor network.

Deliverable: In this work-package the final deliverable will be a mobile water-quality sensing robot with autonomous motion control and data transmission capability.
