Protopiper: Physically Sketching Room-Sized Objects at Actual Scale
summary
A handheld device that folds adhesive tape into hollow tubes and cuts patterned ends with a hot wire builds room‑scale, lightweight frames for furniture and props, including sofas, a kitchen mockup, a working drawer, and an umbrella. It uses servo motors and an Arduino Nano to feed, seal and cut, adds living‑hinges, bearings and a wing connector for 70–80% of joins, and supports 200–300 cuts battery life. A 16‑person study yields 16 participants rated 5.88/7 for usefulness; core idea is adhesive tape folded into hollow tubes.
