PROJECTS:

Title: Kinematic thumb motion analysis during the manipulation of syringe task Jan 2011-Apr 2011

Description: The original inspiration for the study was the development of osteoarthritis in CMC thumb joints of nurses. Measurement of the kinematics heretofore in this study, the magnitude and direction of forces applied to the thumb during the plunging action can be measured and applied to determine individual joint forces.

Title: Controlling seven DC motor’s using PIC18LF4331 Aug 2010-Dec 2010

Description: PICLF4331 microcontroller was used to control seven DC motors by generating seven PWM (Pulse Width Modulation) and transmitting these signals through PID controller to control position and velocity of the DC motor. PWM were generated using MPLAB IDE software and practical experiments were carried out to confirm the results from Matlab/Sim Electronics.

Title: Designed Optimization of the Domestic Refrigerator Mar 2009-May 2009

Description: A detailed thermodynamic model for a refrigerator based on a simple vapor compression cycle was developed with the focus on heat exchangers and capillary tube. A full factorial based design of experiments (DOE) was implemented to find optimal design values for design variables. Material cost advantage was achieved from this work.

PRESENTATIONS:

Title: Human Finger Joint Synergies for a Constrained Task Applied to a Dexterous Anthropomorphic Hand

Presented at: US National Committee on Biomechanics 3rd Symposium on Frontiers in Biomechanics: Mechanics of Development, Farmington, Pennsylvania, USA.

Description: This presentation describes how the complex task like unscrewing a bottle cap is done with a dexterous anthropomorphic hand. Human motion profiles of test subjects were recorded using CyberGlove II and the data were analyzed for unscrewing a bottle cap. A reference joint is given a sinusoidal input, and the remaining joints are scaled in phase and amplitude with respect to this reference joint. This significantly reduces the computational cost and complexity of the task.

Title: Double Ram Shaper

Presented at: Jawaharlal Nehru Technology University (JNTU), Hyderabad, India.

Description: The objective of the presentation is to project the idea of converting the traditional old shaper to a new Double Ram Shaper, which can be used as Special Purpose Machine (SPM).

ACHIEVEMENTS:

Attending training on Six Sigma, Jan 2011.

Won First Prize at National level Seminar conducted at JNTU, India for the presentation on Double Ram Shaper, Mar 2009.

Won Second Prize in Quiz competitions at JNTU, India, Mar 2009.

Participated in “POSTER PRESENTATION” at Guru Nanak Engineering College, India, Apr 2009.

Participated in some more activities like “NOCTURN MACHINES” conducted at JNTU, India, Mar 2009.
