Ripple Wall

Changing How We Interact With Art

Project Description

This project is one part of a larger piece. The finished project will be an interactive wall with many panels folding in and out to create patterns and wave-like movement across the wall. The first module of the wall is completed and moving. From here I need to replicate this module and connect the components all in code. For this project I am refining my Arduino skills and learning how to coordinate multiple moving pieces in code. Once there are more servos I will need to get them all in sync to create the movement I want.

This is how the servo attaches to the module. At one point I was having trouble with maintaining rigidity where it was needed. The 1/8in acrylic I used was warping and the adhesive was not keeping the system together. There was also an issue with the way the acrylic cut, making it so the finger joints I used were not flush. To compensate I recut the frame with a 1/4in plywood. This was a significant improvement because the material is not as warped and there is more surface area to attach the midsections to. I also added a 5th rod in the middle of the module.

There is a pinion attached to the servo motor which moves the rack linearly. That rack then moves four more pinions which create that open and close motion. The pieces that attach directly to the servo including the rack and pinion are an open sourced design. The rack was adapted from that open sourced design to fit this purpose. I designed all pieces of the claw itself. I plan on cutting down on the material used in the next iteration.
