Tricycle Research

I have spent the past two years pursuing independent research, to create a power steering system for physical therapy patients using recumbent tricycles. As the principal investigator, I recruited two colleagues, and we have received $21,000 in funding from Northwestern University to prototype a Bluetooth hand-held sensor paired with a motorized tricycle. This initially started as a class project that I continued, with the help of faculty advisers. I wanted to add motors and sensors to a previously-made design but it was outside of the scope of the initial project. I spent months meeting with professors, physical therapists, engineers, and many others professionals in various fields. I submitted a proposal to turn my idea into a research project in Northwestern’s Mechatronics Lab and it was accepted in March of 2023.

Tricycle: I constructed this small scale tricycle that mimics the movements of a full size tricycle that is used for adults with limb mobility issues. This uses Pico-microcontroller, a motor driver, and a Bluetooth device, which are all powered by AA batteries.
Sensor: To test and compare five sensors (e.g., joystick, accelerometer, etc.) I soldered this PCB (printed circuit board). Output data was collected about the accuracy, consistency, and speed of each sensor, and we analyzed the results to select the optimal sensor.
Presenting: Our team was invited to present our research in Long Beach, California at the National Council of Undergraduate Research in 2024. We also presented our research at two local research symposiums.
