INTERNSHIP EXPERIENCE

Robotics Engineer July 2014 – Sep 2014

LEMA LABS Chennai, India

• Successfully built line follower robot, obstacle avoider robot, tabletop robot, remote controlled robot, and pick and place robot using microcontroller Atmega16 and Arduino

• Assisted for advanced functioning robots that involve pulse width modulation, analog-to-digital conversion, Internet controlled, interfacing Arduino and Atmega16

• Digital Weighing Scale - It was developed using load cell (weight from 0-40 kg) with Atmega 16

• Successfully built Line follower robot using Arduino that completed the given racing track within short time PROJECT EXPERIENCE

• Optimization of the fundamental frequency of beam with flywheel and pulley Using MATLAB April 2020 Increasing the fundamental frequency of the system by determining the position of flywheel and pulley on the shaft by using hand calculation of cantilever beam deflection of the model due to static load. The fundamental frequency of vibration of the system is found in terms of the position of flywheel and pulley. Therefore, MATLAB is used to solve for the differentiating the frequency equation.

• Design of Automotive suspension system by analysis of base excitation Using MATLAB Dec 2019 The application of this method will be calculating and modeling the response of a suspension system. By calculations and data, we can design a system for the comfort of the occupants and the longevity of the vehicle.

• Experimental analysis of a car suspension for ride comfort using MINITAB Nov 2019 This project presents the use of analysis of variance (ANOVA) with the fractional factorial method in studying the effects of suspension design parameters such as tire pressure, damping coefficient, stiffness, sprung mass, camber, toe and wheel speed. Different values of design parameters of suspension are used as input matrix and the output data are analyzed using MNITAB 18 software program and design of experiments to plot the main effect and interaction effect between all design parameters for the response of ride comfort. Ride comfort is the vertical acceleration of the unsprung mass. The lower the RC the better the performance.

• Testing the strength of bamboo reinforced composite material Nov 2019 A composite was created to study how changing the proportion of fibers inside of a composite change the strength. Chopped bamboo was used as the fiber and ice was used as the matrix. The samples were frozen and then introduced to drop test. The height at which the tile breaks for each proportion is recorded and noted down for calculation impact energies. The impact energy at which the composite fractured represents its strength.

• Optimization of vehicle speed for the given racing track data and vehicle data using MATLAB April 2019 A MATLAB program is computed using the rare wheel drive vehicle data & circuit data to display the total lap time, the maximum and minimum speed on the given racing circuit map. The circuit is completed by racing car with knowledge of constant acceleration

(Longitudinal), constant braking(deacceleration), wheel load under cornering(Lateral) and to make sure no rollover or ski sideways occurs. The whole model is assumed to be a bicycle model.

• Digital Weighing Scale Sep 2014

Designed a weight scale that calculated the of any object(0Kg-80Kg) that is measured using the Load cell. A load cell with low output voltage (Mv) is amplified (into Volts) using an instrumentation amplifier. Further, it is fed to the analog port of microcontroller Atmega 16 which converts the respective amplified signal into digital output and displays the weight of the object in LCD screen.

• Development of land mine detection robot April 2014 This senior design project detects buried landmines using the proximity sensors. Further, it sends the location of buried land mine by means of latitude and longitude position which is tracked by GPS and sending data using GSM modem to receive locations as a message to mobile and also display the location in LCD screen.
