Sumo Robot - Systems Interfacing

• Given the parts and told to design and create a robot that meets the required specifications.
• Designed robot shape and measurements  and created a mock shape using construction paper.
• Worked with power tools such as a band saw, drill press, and a dremel to cut the metal into the correct shapes and sizes.
• Using C code and embedded systems programmed everything individually and then put everything together.
• Sent PWM signal to motors and altered frequency to change speed.
• Programmed an infrared sensor to act as the robot’s “eyes”.
• GPIO inputs for reflectivity sensors used to keep robots in bounds
• Won 2 of 3 matches

Senior Design Project

Automatic Guitar Tuner (Intunegrated)

• Collaborated within a group of 4 for the entire senior year.
• Presented during weekly meetings and progress reports.
• Researched how guitars worked and how different existing tuners worked.
• Tasked with designing the entirety of the project within the first semester.  Then creating a prototype in the second semester.
• Designed electrical schematic of the overall system using NI multisim.
• Found parts and kept track of pricing of all components.
• Set schedule and deadlines for different project milestones.
• Utilized a fast fourier transform to find the recorded frequency 
• Tested different DSP algorithms using MatLab to find the most accurate.
• Designed gear mechanism to hold string similar to a tuning peg.
• Communicated with motors via I2C communication.
• Created I2C driver specifically for our project and micro controller.
• Programmed real time code in C using embedded systems.
• Designed a control system to spin a DC motor for a specific amount of time.
• Successfully tuned a guitar mockup to multiple different notes.
• Presented design at the end of the year to faculty, investors and anybody that was curious.
