Calligraphy bot

Gloria Zhu '26 and Lee Liu '26 set out to make a calligraphy machine during IAP 2024. They built its mechatronic parts in a month; then, fueled by Hershey's dark chocolates, they put in many late nights in the Metropolis makerspace's electronics mezzanine to finish the job. The resulting device can move its brush pen with five degrees of freedom, and its carriage moves up and down to vary the stroke width.
