Crafting Material Interfaces

Super Slow-Moving Paper

The idea, here, was to come up with some interesting paper-mechanisms and actuate them using flexinol. The title might give you some indication of how well that all came off. The folding went reasonably well. This is a miura fold, a kind of square tessellation. It’s very easy to do, and folds down flat. All of [...]

Moving Snake

Many movement in nature, whether in animal or plants are caused by contraction and expansion. Similarly, flexinol also contracts and expands. Could flexinol be used to replicate nature’s movement?   A string of round wooden chips could represent the body of the snake Ideally when strung together, contraction of flexinol will make the snake “move” [...]

Actuators Project

Due: 3pm, Tuesday, November 29, 2011 See student posts here Working either individually or in a small group (2-3 people), you will experiment with material actuators in a hands-on project. For Tuesday’s class you should prepare a 5-10 minute presentation and a blog post that documents your project. Your presentation and blog post should include: [...]

Giving You The Finger, or How to Make a Homemade Small-Footprint Jamming Device (using Fluids instead of Air)

Having done research on soft robotics actuated by air, I wanted to create a simple device that will allow me to test and play with jamming with various fluid instead of air. I was  inspired by the Japanese soft robotics hand that we showed last week. The voiceover and subtitles explains how this works, where [...]

Crouching Beaver Hidden Institute

Overview I wanted to experiment with the thermochromatic ink that Leah showed us last week.  Just a reminder: thermo  = heat and chroma = colour.  It is an ink that changes its behavior when the temperature rises over a certain base level.  For example:                       [...]

Shape Memory Alloys (SMA)

Elastic Pneu-Actuator

by Daekwon Park & Woong Ki Sung Inspired by the hydro skeletons and muscular hydrostats in nature (e.g. elephant trunk, starfish, octopus arm, etc.), the kinematics are based on the combination of elastic material body actuator and pneumatic pressure feedback system.
