Granular-Jamming Vise

Granular-Jamming Vise cover

A pneumatically actuated vise using granular jamming to grip irregular workpieces.

ReVise is an integrated vise solution designed to hold tightly onto irregular workpieces without damaging them. The metal vise houses a self-regulated pneumatic system attached to two removable pouches. Through granular jamming, the pouches can conform to any geometry and hold their shape. As a result, the clamping force is distributed over a larger contact area, improving grip while minimizing risk.

This was the product our 20-member team showcased on December 6, 2021 in Kresge Auditorium for the capstone project class 2.009 Product Engineering Processes. During the presentation, we clamped a raw egg without cracking its shell. Getting there meant iterating through the process Prof. David Wallace summed up as “Ideate. Model. Test. Repeat.”

My role

I headed the task force responsible for designing and manufacturing the vise body, built mainly from waterjet-cut steel plates welded together. I also created the team’s CAD assembly, renders, and animations, and designed the brochure, posters, and slides for our 20-member team.
