ShopBot Camera Arm – Handsfree Project Documentation

I’ve been wanting an extra set of hands to hold a camera while I document projects for a long time. Kari and I are writing a book for MAKE all about soft robotics, and I figure there’s probably not going to be a better time to have a serious documentation setup than when someone’s paying me to do a good job at it. Since NYC Resistor just got a ShopBot and I’ve been meaning to get back into plywood fab for years, it seemed like a pretty auspicious syzygy. If you’d like to replicate this design for yourself, you can find the source files and project notes here. You can also see my photos from the cutting and assembly of the project here.

Tardis Ring

dsc_8416Years ago, I designed a series of Tardis and Dalek rings as an experiment in SolidWorks modeling. I wanted to have a ring design that would support a sculptural element with a shank that would change proportionally to feel natural in a wide variety of ring sizes. I was also way into Dr. Who at the time. Continue reading

Requiem for Rhinos at the MIT Media Lab

A few months back I reprised my role as robotics mercenary and general fixer, spending a week working on David Nunez’s Requiem for Rhinos installation at Illuminus Boston. David is a researcher with Todd Machover’s Opera of the Future group at the MIT Media Lab. The idea at the core of the sculpture is the passing of Nabire, one of the last northern white rhinos in existence. Only four remain and they are so closely related that rekindling the species is impossible. The sculpture was conceived as a grand send-off, with Nabire’s kin descending from the ceiling to wish her on her way.

The Neucuff – A Soft Robotic Exoskeleton

Over the past six months Kari Love and I have been developing a soft robotic elbow orthotic for Cerebral Palsy therapy. It’s still in the early stages of prototyping and testing, but it’s making rapid progress. If all goes as planned, it should be in the hands of a team of CP doctors specializing in robotic orthotics in the near future.

Here’s a bit more background from the Hackaday page:

The Neucuff is an extension of the soft robotics development I’ve been doing for the past three years as lead scientist at Super-Releaser. After creating manufacturing techniques for a few different flavors of soft robot, I felt it was time to find some practical applications for the technology.

I approached a ton of people about where soft robotics could be best applied. I talked with civil engineers about exploratory robots for mapping pipes in construction sites. I talked with NASA scientists about soft robots in space. The most promising ideas came from my father, an orthopedic surgeon specializing in arthroscopy and shoulder reconstruction, and my robotics mentor, who has spent the last ten years in the medical device field.

They both described problems with therapeutic robots that a soft robotics approach could solve. Soft robots are good at spreading force evenly across a large area. Soft robots are conformal so they can fit a wide variety of applications and environments by design. This makes them an ideal candidate for Cerebral Palsy therapy.

The Glaucus

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.

quad_03The Glaucus was created to demonstrate a method for fabricating soft robots of nearly any geometry with arbitrary interior structures. It’s been my goal, since beginning my research into soft robotics, to simplify the process of prototyping and refining designs. Often the barrier between an interesting bench prototype and practical application is how it scales into production. If methods for experimenting with the core concepts, evaluating them in a context that represents their final manufactured state, and refining them for mass production don’t exist, the idea is very likely to languish on the bench.

SOLS Adaptiv – A Wearable Soft Robot

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.

The project started out with an external shell modeled by Continuum Fashion. Although the design was elegant, this posed a challenge for introducing the robotic elements and the engineered components that would stitch everything together. Since the external shell was generated in a mesh CAD program, it didn’t fit into SolidWorks’ reference frame. This meant using the mesh as a reference and generating a simplified surface to extrude the soft robot elements and retaining skeleton from. Continue reading

Glowy Crystal Ring

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.


Soft Robots

I’ve been working on this project for a few months, focused on changing how soft robots get designed and made. Traditionally these robots are complex to design and build, and they require and unexpectedly large amount of hand labor to stitch together. This ends up with parts being produced slowly, with small deviations from known working designs. I’ve been trying to come up with a method that allows you to design a robot in CAD, queue up the design on a powder printer, cast silicone into the printed mold, and pull out a working robot. The idea is to allow for a huge variety of geometry, experimentation, and prototypes that are quick and inexpensive to produce. I want to make the process a whole lot more like a scientific experiment, where you test and observe multiple samples while adjusting a single variable. Continue reading

Refurbishing NYC’s Historic JJ Hat Center

A few months ago I was commissioned to restore a storefront over on 5th and 32nd st, JJ Hat Center. They’re long time clients, partners of the good folks over at Pork Pie Hatters. I’ve done a lot of work for them over the years, building their website, designing custom hat blocks, making marketing materials, and creating the branding for their series of handmade hats. This was a whole other level of project, though.

To start, the building used to be an IBM adding machine factory and showroom. When JJ’s took it over, they installed a lovely wood exterior. So, on the plus side, there is a lot of old NYC richness both inside and out. On the downside, the wood exterior had fallen apart in the intervening years. Part of my job was to see through the decades of wear and tear and come up with a plan for refurbishing everything to resemble the original without spending thousands on custom parts. Fortunately my friend Clark put me in touch with a few very talented carpenters. So, with some meetings and design drawings, they were rolling on building the elements for the exterior.
