C Ashish Kumar 2008 B.Tech Probabilistic Learning of 2-D Grasps
The project aims at building up a learning model for a 2-fingered system for manipulating a 2D object. The need for learning model arises primarily because of constraints such as lesser computational power available in micro robots. Learning model eliminates the costly computations of Newtonian formulations and hence assists in achieving real time task execution. Work is divided into two major domains of prediction and control. Initially various suitable prediction algorithms were studied and some of them were tested on sample environments. Use of Artificial Neural Networks as prediction model is finalized on the basis of performance of various algorithms. In the second part a control model for achieving a particular task was proposed. Algorithms were used to develop learning methodology of this control model and their efficacy is judged on the basis of accuracy and rate of learning.

Vardhman Jain 2008 B.Tech Boundary Element Method (BEM) Based Study of Cardiovascular Bubbles in presence of Gravity
To understand the behavior of a bubble sticking onto the wall of a 2D channel under gravity driven flow, simulations have been carried out using a Boundary Element Method (BEM) based code. A complete parametric study has been presented in which two cases of the orientation of gravity vector have been considered; gravity at and angle of 45 degree to the cannel axis and in the same direction as the axis of channel. Three cases of Bond number have been studied; Bo = 0.1, Bo = 0.5 and Bo = 1.0, to ovserve the effect of variation in the strength of gravitational force compared to surface tension effects. Four values of initial bubble pressure, 1,2,4 and 8 have been used for simulation of the bubble evolution with time. Then this existing model has been extended to have two bubbles sticking on opposite walls of the channel. A detailed parametric study of this model has been presented with two cases of orientation of gravity vector, along the channel axis and perpendicular to it. Four cases of initial bubble pressure were considered for each of the two orientations of gravity and the results have been presented and discussed. Finally, attempts to modify the code for having single finite bubble inside the channel have been presented to give the readers an idea about the concepts involved in the process.

Akash Agrawal 2008 B.Tech Computer Assist in Knee Osteotomy
This project is aimed at developing simulation techniques for surgeries on knee. With advent of cheap computing power and availability of good modeling and simulation tools it is now possible to develop virtual models of human body parts and analyze the effect of various modifications that it can be subjected to. In this project the subject of interest is the knee surgery and the particular surgery of interest is tibial osteotomy. In tibial osteotomy a wedge shaped bone is removed from tibia and then realigned to correct the deformation in the bone. This is a sophisticated process because ligaments and soft tissues are subjected to stresses during the incision and realignment of bone. The aim of this project is to develop a software technique which will predict the allowable size of wedge that can be removed from tibia of a patient. Finite element modeling and analysis techniques will be employed to carry out the analysis.

Arpan Gupta 2008 B.Tech Investigations into Microflights
Insect hovering flight has been a topic of sustained interest to engineers and designers of Micro Air vehicles (MAV). In order to unravel the physics behind the insect flight, large number ofresearchers (Ellington (1996), Wang(2000) have carried out computational and experimental studies for optimizing the lift and drag characteristics in different scenarios. The computational analysis reveals the mechanism of vortices formation from leading and trailing edges of elliptical wing. This vortex dynamics fruther explains the effects of different parameters on the lift and drag forces. Insect flight is strongly influenced by the choice of hovering motions. Conventionally the hovering motion utilizes an initial rotation cum translation motion (r), translation motion(s) and finally rotation cum translation motion (f) during a half cycle. This type of motion is popularly known as figure-of-eight motion (Lighthill(1973)), which mimics the motion of wing employed by many insects. The primary objective of the present study is to investigate such hovering flight under the generalized pre-described motion and to determine the optimal parameters (r,s,f) which results in maximizing the lift characteristics. Further, the effect of variation of Reynolds number is investigated and comparison of metabolic power characteristic and simulation power characteristic is performed. For capturing the unsteady physics of the flow, a semi implicit, pressure-correction type scheme, on a non-staggered structured body fitted grid mesh using a finite difference type of spatial discretization is employed.

Nitish Sabharwal 2009 B.Tech Manufacturing of an artificial cartilage testing rig providing optimal flexion extension motion under constant loading
This project aims at developing a system for testing of artificiAl cartilage which can then be a replacement of the natural cartilage of arthritis patients. The present procedure of arthritis treatment involves the total replacement of the femoral condyles and tibial menisci by artificial prostheses.
Shubham Rao
This has been done by physically emulating the natural motion of the knee on an experimental setup consisting of femur and the tibia (made of steel). The motion emulated has been the sitting-standing cycle of a male weighing 80 kg. A set of bevel gears provide flexion-extension motion to the femur as well as lateral rotation of the tibia. Load on the knee is provided by the adjustable spring, thus incorporating the total natural knee motion during the sitting - standing cycle.

Keywords: Sitting and standing cycle, Femur, Tibia, Flexion-extension, lateral rotation, CAD, ICR.

Richa Bansal 2009 B.Tech Rollover Stabilization in Electric Vehicles
Rollover is conventionally resisted in vehicles through passive design techniques like low CG height to wheel-base ratio and some suspension design principles. Of late, active traction and suspension control has been suggested to limit rollover instances. Electric vehicles, where all the wheels are motor driven, are stated as the solution of the future to meet environmental norms and are receiving considerable attention as a substitute for present gasoline fuelled vehicles. With the advent of motors that can drive as well as achieve a stopping distance of 100 m from 15 m/s, some new possibilities emerge for rollover control.
Tushar Sharma
The automobile trajectory is defined by rigid body kinematics once rollover initiated. Since a rollover incidence, from wheel lift-off to impact takes as much as 3 sec., the possibility of active intervention by actuating the motors attached to the wheels can be investigated. In this study, necessary motor orientations and torque are determined, which can be used to control vehicle rollover when airborne. It is done using the gyroscopic principle, and also through the use of reaction wheels. This arises from the availability of independently controllable actuators for each wheel. Another possibility investigated is the application of an external stabilizing torque provided through a shaft coupled with the in-wheel motors. The dimensions and mass of the shaft is thereafter optimized. The two cases under consideration are sideways slip and turning of the vehicle around a corner.
Aryaman Tandon 2009 B.Tech A
An autoclave is a pressurized device designed to heat aqueous solutions above their boiling point at normal atmospheric pressure to achieve sterilization. This process is referred to as autoclaving. All bacteria, fungi, viruses and other microorganisms are inactivated. It has wide applications in microbiology, medicine, sterilizing instruments for body piercing, veterinary science, dentistry, podiatry and metallurgy. Certain plants, which find rich applications in biotechnology and medicine, are preferred to grow in a sterilized environment. This exclusive presence enhances their growth and has rich yields. The maintenance of such plants so far has been a difficult task, as autoclave environment has to be free from the microorganisms. Manual maintenance makes it very prone to contamination so the use of a robot, which successfully works in an autoclave environment, is needed. The robot is itself autoclavable and remains inside the autoclave chamber at all times. The robot does the maintenance of plants in the autoclave chamber and the air-tightness of the chamber ensures there is no contamination from outside environment.
Siddharth Khattri
The basis concern of the project is to design such a robot that remains in an airtight container and can survive at elevated temperatures. However, it is to be understood that the working of the robot will not be on elevated temperatures. It only has to survive the high temperatures when autoclaving is done because the robot will always sit inside the vessel.
In the course of the project, we needed to apply various mathematic tools and equations to generate a planar workspace of about 0.2 m2 where operations like cutting and gripping can be carried out by the robot.We designed a parallel mechanism, then we derived the parallel and inverse kinematics of the robot, then we generated the workspace of the robot using computer simulated graphs and optimized the dimensions of the robot elements to obtain a preferable large planar workspace. In the second half of the second semester, we manufactured the robot.
Ripul Bhutani 2010 B.Tech Repositioning of Human Body Models
The mesh generation stage in a finite element (FE) problem Involving complex geometries is not only cumbersome, but also time consuming. Automotive safety engineering has heavily relied on Anthropomorphic Testing Devices (ATD) for evaluation of injury measures which are now on the threshold of being replaced by FE Human body models for impact. Mesh creation for such human body models take analysts days together. Furthermore, the geometry of most of these FE models is limited only to standard occupant or pedestrian postures. In real life however, the body can be in various postures such as standing, walking, running or jogging. Compromises due to non-availability of FE models for different postures may lead to erroneous conclusions and may limit the use of these models. This study reports a methodology to generate anatomically correct postures of existing human body finite element models while maintaining their mesh quality. The developed method is based on computer graphics techniques and permits control over the kinematics followed by the bones. Agraphical interface has been developed to implement the said methodology. This software has been tested on the knee joint. Once completely developed the software will be employed in crash simulations, with the occupant place in different postures. This is a big step towards out of position crash simulations and injury prediction as all the simulations done up to now have employed one standard sitting posture of the occupant.

Marathe Ratnakar Shrikrishna 2005 M.Tech Material Characterization of Soft Tissues in Compression and Impact
The project establishes the procedures to characterize human body soft tissues in compression and impact. Two test rigs were developed in order to test the human body soft tissues under the dynamic and quasistatic loading. The rig developed for the dynamic loading is Split Hopkinson Pressure bar. This rig was used to establish the strain rate dependency of the human body soft tissues. For the quasistatic loading, Indentation test was carried out. It gives the load deformation characteristic of the tissues of quasistatic loading condition. To derive the constants for the analytical model, the process of inverse mapping was used. In this technique the experimental load deformation is mapped with that found out by FE Simulations. The analytical model chosen was the Mooney Rivlin material model. Curve fitting was used to derive the Coefficients for the 3 parameter Mooney Rivlin material model. The sensitivity analysis of the 3 parameters was done by the TAGUCHI method. The thesis finally brings to light the strain rate dependency of human body soft tissues tested with the help of the developed SHPB test rig.

Keywords: Characterization, Split Hopkinson Pressure Bar, Indentation Test, Strain rate Dependency, Mooney Rivlin Material Model.

Vinay Kumar 2005 M. Tech Studies on Vibration Monitoring of Turbine Blades
Turbine blades require constant monitoring of vibrations. This project report highlights the importance of monitoring of blade vibration in rotating condition of turbine. It also describes in brief various insturmentation systems and methods that have been used so far to measure the vibration of rotating blades. Following an examination of present day measuring systems for blade vibration in turbo machines, particular reference is made to the method of differential time measurement. This also contains the description of work done in IIT Delhi so far.
   The report describes the existing setup for monitoring the turbine blades vibration, which has two proximity probes and one hall probe. This setup having four blades on disc is in the Vibration lab, in IIT Delhi. In this setup compressed air is being used to excite the blades. The existing set up was using CRO for monitoring the signals. The existing setup only gives the amplitude of vibration.
    The new experimental setup, having three proximity sensors and 16 blades is being used in the project. The new experimental setup has been designed in the work and description of which is also given in the report. It can run upto 3000 rpm. There is a description on all major components of setup and instruments being used in the experiments including rubbing arm, which is being used for excitation of blades.
