Mechanical Engineer

Focused, dedicated and talented technologist with a unique combination of high education and part

time job experience in designing and modeling. Excellent m echanical engineer worked in strict

deadlines within technically demanding environments. Designing includes d evelopment of 3D models,

specification generation, placement of the products and dynamical analysis. Major projects include

the autonomous robots, robotic arm, vending machine, pan tilt platform, hexapod, inverted pendulum,

engine parts and simulator for commercial aircrafts su ch as Boeing 777-200ER integrated with

hexapod to realization real scenario and electromechanical actuators etc. I have done lot of work in

the 3D modelling software. I have used SolidWorks and Pro Engineer for 3D modelling of hexapod,

double inverted pendulum, inverted pendulum, unmanned aerial vehicles and pan tilt platforms. I have

also used SolidWorks and VisualNastran-4D for dynamical simulation of the products. Also, fluent in

English, both written and orally. I have worked on subsea mechanical design ing in the university

labs.Rapid prototyping of engine parts. Published results from research in 4 journals while also

attended and presented the research findings at 3 engineering conferences internationally.

RESEARCH THESIS

Design, Modeling, Stability Analysis and Motion Control of a Mechatronic

System.

The research work is a contribution towards Unmanned Aerial Vehicle’s (UAV)

development aiming at design, modeling, stability analysis and motion control of

Pan Tilt Platform (PTP) for a video camera. The PTP with motion controller is a

device that makes possible for the sensors to point in a desired direction. Th ere is

a growing demand for control systems with motion tracking ability. The practicality

of this research work can be extended to a broad range of applications. Of these,

the most apparent use is in defense, where there is a strong emphasis on reliably

neutralizing threats without risking human life. Unmanned aerial systems can

provide significant reductions in manpower and risk to humans for critical security

and defense roles. UAV can carry electro-optical payload to areas where it would

be dangerous for a human to go, and they can transit between operating stations

at high speeds, allowing for quick response to changing situations. Unlike ground

vehicles, UAVs are highly mobile in rough terrain and urban environments.

This thesis covers the PTP design based on kinematics, modeled with three

different techniques and stability analysis of each model. Then motion controllers

are designed based on system dynamics and linguistic knowledge. The

conventional, modern and hybrid control schemes are developed for PTP. Linear,

nonlinear and bond graph models of the PTP have been derived and stability of

PTP is analyzed using identified parameters. The performances of Langrage -Euler

based mathematical model are compared with PTP dynamics simulation in the

integrated dynamic simulation software’s. This provides an accurate model of

engineering systems such as electromechanical systems for performance and

qualities evaluations. The model is a total torque, angle representation in three

rigid body degrees of freedom in case of Newton-Euler and Lagrange-Euler. These

models are generalized, modularized and analytical representation of a PTP. The

Bond Graph Model (BGM) is a precise mathematical model of the physical system

in the sense that the state space equations of the physical system can be unfolded

from the BGM. This is used to obtain the model of multi-domain mechatronics

system. The novel controller is developed based on hybrid control scheme and

novel model of mechatronics system based on BGM.

The function of motion controllers is to track the desired inputs such that PTP

points in desired direction. Based on initial position and output angles from motion

controllers, the forward kinematics finds out final position (x, y, z) of camera and

these coordinates x, y, z are compared with desired coordinates in image

processing unit (IPU) and Laser range finder (LRF). The image grabber grabs the

image from the camera mounted on the PTP and sends it into IPU. The IPU with

LRF finds the desired x, y, z coordinates of the targe t. The coordinates are then

sent into direct calculation / inverse kinematics unit and it converts these

coordinates into desired input angles which are the inputs of motion controller.
