RELEVANT ACADEMIC PROJECTS

Optimus Prime – FreeRTOS based Self-Driving Car using CAN protocol Fall’14

Designed and developed the hardware for the car.

Worked on different modules like SONAR sensors, stepper motor, Electronic Speed Control, Servo Motor and LCD.

Designed and optimized algorithms for self-driving capability based on GPS and Sensors.

Developed Linux kernel modules, modified application programs prototype board for ARM 11 kit Spring’14

1.Analog sensor interface along with data validation

Digitized the output of analog sensor and validated the digital data by computing FFT and plotting power spectrum.

Designed pre-processing circuit and compensation function ensuring that majority of the output is in linear range.

2.Stepper motor control with speed variation using PWM

Controlled the direction of rotation and speed of a stepper motor depending on the feedback error signal. The speed was determined by the PWM frequency calculated from this error signal using the concept of PID control.

Wireless 3D Motion Tracking using GY521 (Gyroscope & Accelerometer), Xbee Fall’13

Interfaced GY521 and Xbee wireless module to Arduino Uno to track the motion of the object.

Implemented Kalman Filter algorithm to process the raw values sent over the xbee module to another Arduino Uno.

Developed a 3D image using the values in OpenGL.
