Ingenious 3D-Printed Wheelchair Attachment Makes Lever-Powered Rowing Motion More Efficient

When challenged to hack a wheelchair and build the best one possible, students Kate Reed and Stefano Pagani of NuVu innovation school and Nathaniel Tong of Rochester Institute of Technology came up with an award-winning idea. The trio developed the Hand Drive, an affordable 3D printed attachment that allows any wheelchair to be powered by an efficient lever-powered rowing motion.

Rather than reinvent the wheelchair, Reed, Pagani and Tong decided to improve upon existing wheelchair designs. The trio focused on a lever wheelchair model which uses a lever mechanism and rowing motion to move a person forward. Not only is a lever-equipped wheelchair easier on a person’s shoulders and wrists, but it also is faster than push-wheel propulsion that relies on the hands to push the wheels forward. Lever wheelchairs are efficient, but their price tag, which ranges from $2,000 – $10,000, puts them out of the reach of most people.Read more
