Ragini Bakshi

I’m an Electrical Engineering Student with great experience in, and passion for Research & Development. I have over 2 years of Industry experience doing R&D for both the public and private sector, and have acquired strong technical (hardware, software) and non-technical skills along the way. 
I enjoy being creative through my work and hope to contribute to the collective human intelligence in some meaningful way.

Projects

Perceptual Autonomous Vehicle Project

The aim is to design, assemble, and test a fully autonomous vehicle that would be capable of navigating to a predetermined position in a parking lot via GNSS positioning feedback, and then park itself in a designated spot using antenna arrays and angle of arrival principles. Currently the vehicle has 4 arduinos, 1 Pi4, 1 KL25Z, 2 gear motors, 1 servo, 1 camera, 6 Ultrasonic & 5 IR sensors, plus 7 analog RF modules and a low-cost u-blox GPS module with a patch antenna. Supervised by Dr. Ramy Gohary from the Department of Systems and Computer Engineering at Carleton.

Mini-Projects in C using FRDM-KL25Z Board

To get familiar with the board, completed the following basic projects coded in C (Keil uVision 5 IDE):
● GPIO: Switch and LCD connection to display button presses● ADC: Infrared Proximity Sensor that detects if an object is nearby● DAC: Generated various signals (sine, square, and sawtooth      waves) and output these via different tones using a Speaker ● PWM & Timing: Made a clock that displayed elapsed time and      synchronized LED flashing each second● Serial IO: Multi threaded Application that decodes GPS receiver       information and displays speed, heading data on an LCD panel●  Tachometer reading using laser and IR (video on Left)

Edison Self-Driving Car


Team Lead for Embedded Systems, the biggest group working on the project, and our work involves: researching hardware used (ex. Drivers, PCB boards, etc) to create the vehicle, developing state machines for car control systems (ex. Acceleration, braking), utilizing data communication protocols to interface with IoT devices and sensors, and utilizing ROS to develop robotic applications of the car. Due to Covid, I am handling all the tasks on the Hardware end: currently working on setting up a Raspberry-Pi cluster with 6 Pi-camera modules to capture pictures and data during operation. 

3 Bit Dynamic Counter

Designed, simulated, and remotely tested a 3 bit dynamic counter which was fabricated at Carleton's Microelectronics Fabrication Laboratory, using 4.8 μm CMOS process. The counter was designed to use 2-phase dynamic toggle flip-flops with reset action. It received a master clock input signal (generated off the chip) and generated the 3 outputs. 2-phase non-overlapping clocks generated on-chip were used to drive the flip-flops. The layout was produced to fit within the specified cell frame with a maximum height of 240 λ and width of 230 λ. All design work and simulation work was done in Cadence Virtuoso. 

X86 Tunnelling Game

Made a basic tunnelling game written in X86 assembly code that uses software interrupt service routines to increase programming efficiency. Software interrupts were used to draw the screen elements (rocks and the player), check for key-presses, scroll the screen, and provide a small delay between each frame of the game (e.g. when a new rock is placed at the bottom row). The game was developed on DosBox-X and can be played on a computer screen in VGA text mode.

Op-Amp Layout Project

For a pre-designed 45nm SOI CMOS process Op-Amp with 1.2V supply voltage, a layout was produced and simulated using the proprietary Global Foundaries 45RF SOI Kit in Cadence. This op-amp had 4 distinct parts, starting with bias circuitry on the left, followed by a differential input stage, a common-source second stage and a final output buffer portion. Interdigitation, current matching, common centroid topologies, etc were utilized. 

Solar Cell Design

Designed the Front Metal Grid of a single junction silicon based Photovoltaic cell such that the design minimized fractional power losses. The Silicon Solar Cell is currently being fabricated at Carleton's Microelectronics Fabrication Laboratory, and will be simulated and tested in March 2021 for performance. 

Insulation Fault Detection Bot

Built an autonomous bot that traces the walls of any given facility (at a specific distance range from the wall), detects temperature anomalies (i.e. too hot or too cold), captures thermal and regular images of the regions of interest, blends the two and saves the pictures for offline analysis.

RTK GPS Project at CRC

The main objective of this project was to achieve high positional accuracy using low cost GPS (Global Positioning System) receivers. An RTK base station was setup that was able to support up to 3 independent rovers. Other milestones include implementing the RTKLIB over various operating platforms (windows, android, and raspbian). We also tested several low and medium cost GPS receivers (LEA6S, M8N, M8P) with and without RTK in fixed, mobile, and portable scenarios, and looked at the effect of different environments such as open areas, high building areas, cloudy-days etc. on positioning. A walking test output is shown in Picture 1.
