The Glaucus is a soft robotic quadruped composed of a single seamless silicone part. It has a complex network of interior channels, created via a lost wax process, that turn into actuators when pressurized with air. It’s able to walk with a diagonal gait, similar to a gecko or Glaucus Atlanticus sea slug, using only two input channels.Continue reading
I have an uneasy relationship with my miniature refrigerator. This chilly bastard decided to get clever and fall open over the weekend. I stepped in to the lab to find it iced up and dripping all over the floor. It was running so hard the housing climbed up to something like 90 degrees. Now, maybe I didn’t shut it properly over the weekend, but I’ve seen this fridge swing open when a gnat coughed. It was time for a change.Continue reading
This project involves AC power, high amperage, and high temperatures. Although this project is simple in principle replicating it on your own offers a lot of opportunities to hurt yourself. Proceed with caution.
Microwaves are treasure troves of useful electronic components. They’ve usually got some nice microswitches, a big transformer, a magnetron, and some smaller transformers and rectifiers to drive the display. I found a decent sized microwave hanging out on the street and transformed it into a shop tool I’d been wanting for a while – a spot welder.Continue reading
I was hired by SOLS to help out with their Adaptiv project. The idea was to showcase the procedural modeling techniques, materials, and technologies behind their printed insoles with a futuristic robotic shoe. Jordan Dialto, the industrial design lead at SOLS, approached me in my capacity as lead scientist at Super-Releaser to make a prototype soft robot shoe that could change shape and fit in response to the wearer.Continue reading
Do you like 3D printing, mold making, industrial design, jewelry, and RGB LED’s? You’re in luck, then. I just finished this tutorial for Adafruit and think it’s well worth a look.
In this project, I attempted to make an Arduino powered device that was easy to use, easy to make, and self contained. Every 3d printed component can be done in a single build without support material. The ring has a battery, switch, and USB port. Once it’s together, all you need to charge or reprogram it is a USB Micro cable.
I spoke at the NYC NASA SpaceApps conference last weekend about how soft robots might end up in space in the next few years. I covered mechanical counterpressure suits, exercise on the International Space Station, enhancing strength on EVA’s, and how space turns your heart into a sphere. Stick around for the Q&A segment at the end, where I get to field some questions from real-life astronaut Catherine Coleman.Continue reading
I’m trying to get more people playing with soft robots. I’m releasing open source design files, tutorials, and now teaching classes. They’re a useful tool to add to any roboticist’s engineering toolbox, and if they were more widely known I think we’d see them outside the research lab and applied to practical problems.
I’ve taught a couple of seminars on soft robotics (demonstrating how I fabricate the Glaucus) over the last few weeks. I’m also giving a few talks soon – one at a seminar for engineering simulations, and another at NYC’s Spaceapps Hackathon.Continue reading
I’ve been going to CCC for a while. I’ve given some talks (mostly on the lightning talk track) and have generally had a good time. More and more, though, I’ve gotten interested in gatherings that orbit big events like CCC, Maker Faire, and HOPE. Unconferences, Bsides, and nether-conferences like BarCamp are less formal than a traditional conference, and often have the kind of wiggle room for instant breakout sessions and long Q&A.Continue reading
Designs are getting sophisticated enough at Super-Releaser that it’s time to gather some data. One of our designs, an inflatable arm cuff, needs to move about 20 foot pounds (or pound foots) of torque to be able to overcome the spastic muscle contractions it’s expected to experience.Continue reading
