PG Project: Modeling, analysis, and feasibility study of teleoperator robot manipulator for a battle tank.

Design software’s: SOLIDWORKS 2005 and ADAMS VIEW.

Research center: Combat Vehicle Research Development Establishment (CVDRE).

Description: The objective of the project was to model different types of teleoperator flexible robot manipulator and the feasibility study should be carried out to determine and document the viability of one of the model as best suitable model. The modeling of the robot manipulator was carried out using SOLIDWORKS 2004 software package and subsequent kinematics and dynamic analysis was carried out on the particular viable model using ADAMS VIEW software package and the structural analysis of the robot manipulator was to be carried out using ANSYS software package and fabrication of the viable model was also carried out.

Manipulator is utilized to collect samples around a 20 km diameter circular span where bio-weapons and chemical-weapons are blasted, so that solid and fluid samples is collected by the manipulator and tested in laboratory.

UG Project: Design of bearing bracket/coupler beam assembly fixture.

Design software’s: Pro/E and Ansys

Company: Integral coach factory, Chennai, India.

Description: The main objective of the project was to DESIGN A BEARING BRACKET ASSEMBLY FIXTURE for welding purpose so as to increase production efficiency, productivity rate, high welding efficiency thereby reducing process time, production cost, rejection rate, operators fatigue etc., The purpose of the project was to design a suitable fixture for the cause said above considering load calculations limits, cost estimation of the fixture, analysis for no failure.

MINI-PROJECTS: PG miniproject: Automatic sheet metal coil unwinding technique

Description: This project mainly deals with a solution of unique industrial material handling problem. The main aim of the project is application of sensors in the material handling system. The sheet metal is loaded into the multi-slide forming machine. The machine consists of feeding mechanism to pull the coil from holder which leads to stressing of coil and gets broken hence leads to a lot rejection. Hence, IR sensors are used to unwind the coil holder automatically according to the feed rate of the pulling and feeding mechanism.

PG miniproject: Electrically actuated screw gripper controlled by IR sensors and variable programmable microcontroller.

Description: this project mainly aims in designing of a electrically actuated screw gripper which is controlled by IR sensors and variable programmable microcontroller. It has got a capability to grip a specific width objects which can be programmed in the microcontroller and IR sensor is used to detect the presence of the object in between the gripper

PG miniproject: development of Quadra-pod robot

Description: the main aim of this project is to develop a teleoperated Quadra pod with remote control and precise movement is provided with servomotor control program.
