Go Baby Go
In 2015 my twin brother and I developed a Go Baby Go car with joystick control.
In 2017, 2018, and 2019, I organized workshops in which members of the South Eugene Robotics Team taught middle school students how to add joystick control to toy ride on firetrucks and jeeps.
The workshops have continued in 2022, 2023, 2024, and 2025!
In the spring of 2024 I worked with a robotics class at Blackstone Academy Charter School in Pawtucket, Rhode Island to build a joystick Go Baby Go car, funded by the Brown Design Workshop. The project was featured in articles by The Providence Journal and The Valley Breeze.

In 2015, based on a request from a pediatric physical therapist, my brother and I developed "Crank Tracker," a device that would send a “space” character to pause media playing on a laptop if a patient stopped cranking an exercise machine at the desired rate.

I worked with Emeritus Professor Ted Morse at Brown University to design, fabricate, assemble, and test his prototypes of a portable device for lifting and transferring a person with physical disabilities.

Boost start trike video Benjamin Phelps.mp4I modified a therapeutic tricycle so that it gives a motorized boost when a child presses on the pedals correctly. The threshold for the activation of the motor can be varied with the turn of a knob. The Boost Start Trike was programmed by my brother. It was completed in 2018 and used during physical therapy sessions at the CDRC.

In 2024, I 3d printed and assembled many Interact Switches for the CDRC (Thanks to Michael Turvey and Makers Making Change for publishing the open source design!)
Based on my observations of PT appointments and conversations with a PT, I designed a new button cap with a "brim" so that it has a larger activation surface, with a portion of the surface much closer to the table or floor.
I designed a 3d printed part for easily coiling the cords of the buttons.
I made a video tutorial on how to assemble an Interact Switch, and I helped organize a button assembly workshop with a middle school and high school robotics team.
I also made a video tutorial on how to modify a cordless fan to be activated by an adaptive switch, for use at the robotics team workshop.
