S. Velladurai 2000 M.Tech Development of Mems Vibration Detector
The investigation aims in designing capacitive type MEMS vibration detector acting as an accelerometer to measure the vibration of turbines in jet engines. It has been designed with a central plate acting as a seismic mass and four webs, which are acting as springs and connecting central plate with outer frame. The capacitance change due to motion of the seismic mass is the measure of vibrations.
A mathematical model of the system is derived by assuming it as a single degree of freedom system. But to study the real system, which is continuous in nature, a Finite Element Model is used. Several models are formulated by using Taguchi's design methodologies and the dynamic behavior of those models is studied. Natural frequency and damping ration are the two important factors deciding working range and sensitivity of the accelerometers. An optimized model is designed within the manufacturable dimensional ranges for higher sensitivity and linear response. Then a model is checked for dynamic stresses.

Keywords: MEMS, accelerometer, sensitivity, natural frequency, and linear response.

Atul Jain 2000 M.S.(Res-earch) Dynamic Analysis and Design of Parallel Manipulators
This thesis pertains to the inverse dynamic analysis of the parallel manipulators, and the objective is to design a realistic Stewart Platform type parallel manipulator for milling applications. In order to demonstrate the working of the manipulator a model is built based on the above design.
Different modelling techniques are studied, and the difference between Newton-Euler-Largange is carried out so that an efficient and easy method is being used for the dynamic analysis of the parallel manipulators. The Newton-Euler (N-E) modelling technique for the inverse dynamics is chosen for the parallel manipulators.
Inverse dynamic analysis of two and three degree of freedom parallel manipulators is investigated using N-E modelling technique. An algorithm is developed in MATLAB for verfivation of the results from the dynamic modelling technique. Inverse dynamic analysis of six degree of freedom parallel manipulators is also proposed, and another algorithm is developed using MATLAB. This calculates the actuation force, which is required for the design and control purposes.
The workspace and singularity analysis of six-degree of freedom parallel manipulator is performed, and based on that, the optimum architecture of the manipulator is selected.
Nikhil Ravi 2004 B.Tech Randomized Kinodynamic Planning for Traffic Simulation
This report presents the work done on a project to simulate traffic flow in India. Traditional traffic simulations are based predominantly on lane-following principles, thereby making them ineffectual in a country like ours where traffic does not move in organized lanes. Therfore there is a need for a simulation based on a methodology applicable to conditions in India. Such a methodology has beendeveloped here. Vehicles are modeloed as entities attempting to reach their goal positon in a field of other vehicles by an optimal or sub-optimal path. The motion planning algorithm has to be one which can incorporate the dynamics of the vehicles, and for this purpose, the principles of randomized kinodynamic planning have been borrowed from robotics. Kinodynamic planning can be used to model systems that have non-holonomic constraints. Probability distributions of different vehicles on Delhi roads are used to randomly place vehicles on the road. Rapidly exploring random trees are then used to search the available space for a vehicle in order to find a path for it amongst the vehicles surrounding it. The algorithms have all been implemented in Visual C++. The algorithm also takes into consideration such factors as vehicle dynamics and driver behaviour.

Amitayush Bahri 2004 B.Tech An Orthopaedic Model of the Human Index Finger
This report summarizes work on a project to build an orthopaedic model of the human index finger. Current models involve replacement of the joint with an equivalent mechanism. By avoiding this and using actual surface geometries it is possible to build tailormade models for an individual and predict the effect of changing bone geometry on resultant motion. Applications for such a model can be found in surgery, diagnosis of causes of abnormal joint motions etc. The procedure followed involves generation of geometries of the proximal, distal and medial phalanges of the index finger as well as the metacarpal bone and modeling of the phalanges, metacarpal and collateral ligaments in MATLAB. The resultant model incorporates forces due to both physical bone contacts as well as collateral ligaments. We are able to obtain data on variation of contact points and ligament forces and compare predicted motions of the bones, under various loads, with experimental results.

Anju Taneja 2004 B.Tech Design and Control of a Biped Walking Mechanism
A self-excited biped walkinf mechanism consisting of two legs that are connected in a series at the hip joint through a servomotor is designed and studied to determine range of stability. A torque proportional to angle between the shank and the vertical is seen to sustain a gait. Each leg has a thigh and a shank connected at a passive knee joint that has a knee stopper restricting the forward motion like the human knee. While a torque proportionality constant is to be determined. A mathematical model for the dynamics of the system including the impact equations is used to analyze the stability of the system through examination of phase plane plots.
Vivek Sangwan
For a specified proportionality constant, the range of physical parameters like leg-length and mass of leg for which the system is stable is determined. Using the stability data, a robust design has been proposed. The reasons for instability have been investigated. The convergence to stable limit cycle has been studied. Uniqueness of the limit cycle for a given k has also been verified. The variation of the mechanical energy of the system and the energy being pumped by the actuator has also been studied in order to minimize energy consumption.

Keywords: biped mechanism, self-excited walking, feedback, stability

Mayank Kumar 2005 B.Tech Multi-Fingered Grasping and Manipulation
The project aims at analyzing grasping and manipulation by multi-fingered robotic finger system. The project is to be accomplished in two parts. The first part deals with conceptualizing the prototype finger while the second part deals with the analysis of grasping and manipulation. To fulfill the project a model of the finger system was made in PROE and necessary calculations were carried out ot estimate the power required to drive the system. The model chosen for the study is a three fingered structure with each finger having three degrees of freedom.

Amit Kumar Choudhari 2003 B.Tech Finite Element Modelling of Human Neck
Neck injuries are one of the very frequently occurring phenomena in case of car accidents. Increasing concern over the number of neck injuries has has impressed upon the need to devise new safety features in automobiles. As result one needs to come up with a model which predicts the head neck response under various crash situations.
Ankur Garg
This project makes an attempt to come up with a Finite Element Model of Human Neck (cervical spine) which would be able to predict the response of head under the frontal and lateral loading situations. In this respect, the head neck responses from human volunteers experimets, as obtained in various loading directions by Naval Biodynamic Laboratory, New Orleans represent a unique set of data in the field of biomechanical research. These thesis describes the characteristics of the model developed, the rationale behind the definition of model elements and the performance compared with the volunteer reference.
M.V.Kartik 2003 B.Tech Impact Behavior of Viscoelastic Materials: Simulation and Experimental Verification

Keywords: Viscoelastic, Hopkinson's bar, attenuation, dispersion, spectral methods

Puneet Bhargava
The importance of studying of material behavior of soft materials such as human tissues at high strain rates is becoming increasingly important particularly for use in material models for simulation of protective devices and the parts of human body being simulated. Applying conventional methods for high strain rate testing to non-elastic materials is ineffective due to impedance mismatch between the specimen and apparatus and so a new testing technique (based on Split Hopkinson's Pressure Bar) is needed.
Conventional equations of Hopkinson's bar analysis are not directly applicable since due to viscoelastic nature of Bars to be used in the modified procedure. As the wave propagates through the bar, the inherent material behavior carses the waves to undergo dispersion and attenuation. This necessitates the need for spectral methods to study wave propagation.
Akshiv Singhla 2003 B.Tech Design of Spherical Four Bar Mechanism to Guide wings
A spherical flapping wing mechanism to guide wings in flapping motion has been designed. The flight model of "Encarsia Formosa" was reported by Weiss Fogh. The successive positions of the wing, including pronation and supenation were modeled using Pro-EngineerTM. The synthesis of spherical mechanism to guide the wing using one rotary input was carried out. The mechanism proposed reproduces the forward motion of the flight, but not the return.

Vibhor Mithal 2003 B.Tech Design and Fabrication of a Five Bar Function Generation Mechanism
Traditionally, an elementary level of programmability in single degree of freedom mechanisms has been achieved with the help of adjustable link lengths. With the advent of servo-actuators, multiple-degree of freedom (MDOF) mechanisms could not only be used for this purpose but also achieves continuous adjustability. Amongst MDOF there exists a class of devices which is termed as programmable mechanism, wherein one of the inputs is driven at a references speed while the other inputs are servo-controlled.
Ajeet Kuma
In this project, a five bar mechanism is designed to generate exact dwell as a translatory output function. This has been achieved by varying the length of coupler with time using a servo-actuator.

Key words: programmable mechanisms, dwell mechanism, multi-degree of freedom mechanism.

Abhijeet Rathore 2009 Mini P Tool for Hip Surgery
This document records the process of development of an efficient instrument for the hip resurfacing surgery. Different designs viz. parallel pliers, turn buckle and a hybrid for the surgery are presented. The underlying fundamentals of kinematics of linkages and force analysis have also been discussed. Prototyping of one of the design and further modifying the model by compliant mechanisms comprise the final part of the document.
Rohit Jain
Hip resurfacing surgery involves the reshaping of femoral head to accept a metal cap which sits into a metal cup fitted into pelvis. Currently the method used to resurface the femoral head depends a lot on eye-balling by the surgeon during operation. It involves finding the axis of femoral neck to be drilled upon, which in general doesn't coincide with head axis. Also the instruments involved make it time consuming and error prone.
Sharvil Talati
Simultaneously, a turn buckle mechanism was developed which provides symmetrical motion of two jaws. The problem of small tolerances and wear are also included in the document.
The hybrid design involves the parallel motion pliers embedded with turn buckle to exploit the advantages of both these designs. The design was optimized to take care of the incision size and easy handling. This design was later converted into a physical model by Rapid Prototyping. The prototype was analyzed and valuable feedback was taken from medical professionals.
In the current stage, we are trying to reduce the number of links by shifting to a compliant mechanism. Further work is required to be done on the same. The testing of the instrument can be done by flixing it on different dry bone femur specimens and then drilling through them. The validation will depend on the accuracy determined by the X-ray taken.
