Design and fabrication of a detachable powered tow system for non-electric wheelchairs.
1. Overview
I’m currently co-leading the design and building of a detachable Segway-like powered tow for non-electric wheelchairs under Professor Hod Lipson in Columbia’s Creative Machines Lab. The project combines mechanical design, fabrication, and electromechanical integration to make everyday mobility more accessible.
2. Approach
I help manage project logistics by delegating work between research associates, budgeting expenditures, coordinating with the MECE lab and Makerspace for machining access, and liaising with Professor Lipson. On the technical side, I design CAD components and machine drivetrain parts including steel axles, sprockets, and keyed interfaces, while fabricating the frame from metal extrusions and polycarbonate panels.
3. Results
I have integrated the motor, gear-shifter, battery, and controller into a functional electromechanical system and advanced the project toward a detachable powered mobility platform. The work has developed my ability to move from CAD and machining through assembly, wiring, and system-level testing.
