  • Present patent describes an underwater system for inspecting reservoirs or tanks comprising of:
  • a robotic vehicle comprising of a chassis, a single cylindrical hull mounted on the chassis with wheels and a motor in a motor enclosure connected to a navigation system, positioning system, vision system, and a non-destructive evaluation system;
  • a processing means to control the robotic vehicle and receive a plurality of data from the systems mounted on the vehicle;
  • a control system to drive the vehicle (100) in accordance with the instructions received from the control system.

Key Features / Value Proposition

Unique Modular Design including other Industrial Features:

  • Capable of accommodating multiple non-destructive evaluation sensors, peripheral electronic as well as mechanical systems.
  • It has an encoder-based dead-reckoning positioning system independent of the properties of the fluid.
  • Three-point contact chassis without suspension minimalizes the slippage problem & provides better control of the vehicle.
  • Its on-board platform is capable of real time data transfer of sensor, telemetry & video data.
  • The front two wheels are powered using brushless DC motors and an Omni-directional wheel used at the back to facilitate smooth and stable turns of the vehicle. Further provide better braking and control features.
  • The vehicle is made negatively buoyant to avoid pitch, yaw, roll & heave motion control.
  • The vehicle can be operated under flammable fluidic conditions as well.
  • Claimed invention has large mounting capacity & a plug and play payload architecture.
  • The proposed system is compact in size & modular to enable upgradation of  technology.
  • The system is designed also for online inspection of storage tanks & pressure vessels.
  • The system can also be used for tanks in nuclear power industries & scientific exploration purposes.
