Personal Project

September 2017 - Present

​

• Built​ ​an​ ​autonomous​ ​two-wheeled​ ​robot:​ ​interfaced​ ​an​ ​ultrasonic​ ​sensor,​ ​two​ ​DC motors,​ ​and​ ​an​ ​h-bridge​ ​with​ ​an​ ​AVR​ ​microcontroller; ​built​ ​robot​ ​body​ ​with​ ​Legos

• Programmed​ ​the​ ​microcontroller​ ​in​ ​C​ ​using​ ​an​ ​ISP​ ​programmer;​ ​the​ ​robot​ ​drives forward​ ​until​ ​the​ ​sensor​ ​detects​ ​an​ ​obstacle,​ ​turns​ ​left​ ​until​ ​no​ ​obstacle​ ​is​ ​detected,​ ​and resumes​ ​driving forward

• Debugged​ ​ultrasonic​ ​sensor​ ​using​ ​UART​ ​serial​ ​communication​ ​with​ ​laptop
   

Undergraduate Researcher,

Penn State Intelligent Vehicles and Systems Group

​May 2016 - July 2017

 

• Independently implemented a collision avoidance system for a semi-autonomous wheelchair; created a feedback loop for an LED strip to display a continuous spectrum of colors from green to red proportional to distance computed from multiple ultrasonic sensors

• Interfaced ultrasonic sensors and an LED strip with two separate Arduinos

• Wrote Arduino and Python code to communicate between the two Arduinos and Robot Operating System (ROS) through serial interfaces

• Wrote ROS node in Python to calculate distances from the raw ultrasonic readings, calculate RGB color values based on distances, and transform distances from the sensor coordinate frame to the wheelchair coordinate frame

Senior Design Project Student,

Penn State Rehabilitation Engineering Research Center on Augmentative and Alternative Communication

​August 2016 - December 2016

​

• One of a team of three students who built a device to enable recent laryngectomy patients to use an electrolarynx without a nurse’s assistance

• Designed and 3D printed a bracket with three degrees of freedom of adjustability to position an electrolarynx against a patient’s throat

• Designed and built a remote control with a 3D printed case and push button switch to activate the electrolarynx, soldered components together

• Presented the working prototype in a public design showcase

 

Student,

Penn State Microcomputer Interfacing Course

January 2016 - May 2016

​

• Worked​ ​in​ ​a​ ​team​ ​of​ ​two​ ​students​ ​to​ ​build​ ​a​ ​device​ ​to​ ​unlock​ ​a door​ ​by​ ​sending​ ​a​ ​text message

• Interfaced​ ​an​ ​Adafruit​ ​FONA​ ​shield​ ​and​ ​a​ ​servo​ ​motor​ ​with​ ​an​ ​Arduino​ ​Uno​ ​to​ ​receive text​ ​messages​ ​and​ ​turn​ ​a​ ​door​ ​handle​ ​when​ ​a​ ​text​ ​was​ ​received

• Designed​ ​and​ ​3D​ ​printed​ ​a​ ​mount​ ​to​ ​attach​ ​the​ ​system​ ​to​ ​the​ ​door
