Design and Development of a 6 Degree of Freedom (DOF) Stewart Platform Gimbal for Image Stabilization of Multi-rotors

Project Title

Design and Development of a 6 Degree of Freedom (DOF) Stewart Platform Gimbal for Image Stabilization of Multi-rotors

Project Area of Specialization Mechatronics EngineeringProject Summary

The aim of this project is to design and develop a 6 Degree of Freedom (DOF) Gimbal for image stabilization of Unmanned Aerial Vehicles (UAVs). Image stabilization is an important aspect of aerial photography and surveillance systems. The main function of this device is to remove the camera jitter induced into the video of the aerial platform due to vibration produced by the propellers and numerous aerodynamic forces being exerted on the camera during flight.

Project Objectives

The scope of this project is to design, develop and control a 6 degree of freedom (DOF) gimbal. This device will be used to provide image stabilization to numerous multi-rotor aerial platforms. The project will contribute in providing an indigenous and cost-effective solution for carrying out surveillance flying of multi-rotor aerial platforms thus making the security agencies more effective and providing better security to sensitive private or government installations.

Project Implementation Method

The project aims to develop a device/system which will be implemented as follows:
1.An Inertial Measurement Unit (IMU) will be used to measure the deviation of the platform from the predefined axis in all 6 degrees of freedom (x axis, y axis, z axis, roll, pitch and yaw).
2. Microcontroller will receive the measurements from the IMU and based on that information it will drive the motors in a way as to reverse the direction of motion of the platform hence keeping it stabilized.

Benefits of the Project

This project is desired for UAV’s designed for surveillance purposes for numerous security agencies. This device will enhance the operational capabilities of the UAVs and would enable it to record smooth videos and become a trustworthy source for aerial surveillance.
