Project Summary

An Autonomous Surface Vehicle( ASV) is an unmanned surface vehicle which is used for coastal security, mines detection, collecting sample data and taking out dead bodies from the harsh environments in lakes, rivers, and seas.  It can also be used in deep and shallow water environments. Various types of ASVs are developed with the focus on improving the target tracking efficiency, fast movement and taking a variety of operations. We have designed a single hull ASV with fixed wings and a movable rudder for controlling yaw motion and is able to track any type of the desired path. Moreover, it is highly manoeuvrable and is capable of turning with a smaller radius. A movable rudder and a thruster which is mounted on the tail section are used to move in a forwarding direction and turn the desired path. All components are calibrated before fitting in the hull. A stability test is performed and the ASV is now fully operated for tracking desired trajectory ad collecting data from onboard GPS and any type of sensor is installed inside the hull. Additionally, the hull is made waterproof for protecting it from damaging the internal components.

Project Objectives

The main aim of the project is to control the position and yaw motion of ASV.

 To develop the electrical circuit of autonomous surface vehicles (ASV).

To calibrate the components such as ESC, RC Motor, RC transmitter & Receiver, and Remote Controller in final assembly.

To test the autonomous surface vehicle (ASV) for position and yaw motion.

Project Implementation Method

The kinematic and dynamic model is developed for simulation of the trajectory of the ASV. The manoeuvrability of the glider is checked by simulating the kinematic model in MATLAB. CFD analysis is performed for calculating the lift and drag forces. Other components such as hull, wings, and rudder are assembled. The internal frame is designed for fitting the electronic components. The stability of the ASV is checked before the deployment of the glider. The ASV is now capable for any type of turning motion

Benefits of the Project

An autonomous Surface Vehicle (ASV) can be used for a variety of missions. We have developed ASV for educational purposes and can also be used for coastal security of rivers, lakes and seas in shallow and deep water. This ASV can also be used for collecting data in any type of environment. Keeping the cost minimum, we didn't install an underwater camera. However, if an additional camera is installed for investigating the behaviour of inside water creatures for research explorations. Moreover, ASV can also be used for mine detection and defense missions.

Technical Details of Final Deliverable

A single hull ASV with fixed wings and a movable rudder controlled by a servo controller is developed. A kinematic and dynamic model is developed for yaw control. CFD analyses are performed for calculating the lift and drag forces using a single BDC motor as a thruster. Moreover, turning motion simulation is performed in MATLAB  by using the developed kinematic model. The ASV is now capable of controlling yaw motion and position control. GPS is installed for tracking the position of the glider. Any type of the desired trajectory can be tracked by this ASV using the APM controller.
