The Adaptiv Robotic Shoe wins a Red Dot design award

The Adaptiv is a futuristic sneaker design that features soft robotic elements to maximize performance while running, jumping, and breaking ankles on the court. The design was spearheaded by Jordan Diatlo of Leadoff Studio for the athletic data company SOLS. The project also featured research and development work by biomechanical engineer Richard Ranky. Super-Releaser contributed to the overall project, building a physical prototype that displayed the soft robotic mechanisms that dynamically adjusted the shoe’s fit and springiness intended to maximize performance during a game.

Leadoff deserves a ton of praise for designing the digital and physical elements in time to premiere at the NBA All-Star Week. I’d like to congratulate everyone who contributed to the project for their hard work and adventurous thinking, bringing such an unusual futuristic design to life. Also, I have to thank Jordan for bringing me in on the process and directing the show.

In the Maker Spotlight

Makezine (and author Caleb Kraft) were kind enough to do a Maker Spotlight interview with me. In it, I was able to talk about my perspective on problem solving, mechanical design, and multidisciplinary research.

From the article:

I’m also really proud of the microscopic tardigrade aquarium I made for Midnight Commercial and Google ATAP. It was this microlens-array powered microscope that looked into a tiny self-contained biome of waterbears, algae, and other microscopic critters we mixed up as an artificial biome – all designed to live in your phone and let you watch this little world through your screen. I got to do everything from design biological research experiments, to diving into whitepapers on micro-optics and tardigrade lifecycles, to simulating EDM cut sheet metal flexures, to figuring out how to cheaply duplicate micro-machined lenses using silicone casting.

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.

Toy Design Studio at NUVU

In 2013, I was splitting my time between running Sleek and Destroy out of my apartment in Brooklyn, and getting absolutely covered in 3d printing dust at Dr. Jim Bredt’s lab while hacking on my first experiments in soft robotics. While one one of those journeys up to Somerville to print, Tess Aquarium pinged to see whether I’d be available to teach a class on digital fabrication and toys at NUVU. I was excited about the opportunity. Also, I was terrified that I’d be creating a summer’s worth of curriculum and teaching a group of eleven students ranging between age 11 and 16 in just a couple of weeks.

A Minecraft inspired bot created by Anna, Felipe, and Patrik out of laser cut plywood, servos, an arduino, and printed tank treads.

The plan I came up with was to start with deconstructing toys, teach some CAD tools, give the students the basics for prototyping with digital tools, and end up with a pretty well resolved final project that was a toy of their own creation. That plan broadly worked, but I also had to do a lot of learning and bootstrapping along the way. Continue reading

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

Tessellating Box

Last night at Resistor Trammell and I poked around with a project to put on the space’s brand spanking new Shopbot. I like tessellating things. Trammell likes putting computationally generated patterns on things.

The plan is to take the box I designed, which will be built from six identical routed panels with hidden finger joints, and apply patterns to the outer faces. I’m excited to see this thing get cut.

Talking Compliant Mechanisms at NYU

Yesterday I gave a talk about incorporating soft robotics, compliant mechanisms, and biomimetic structures into your engineering toolbox at NYU. I’ve been interested in how compliant mechanisms can reduce the computational complexity of tasks like manipulation and locomotion and this talk was a good opportunity to share some of my ideas on the subject.

The general thesis is that biology presents a huge trove of solutions to problems in robotics especially directed at optimizing the amount of sensing you’re devoting to understanding an environment and the amount of computation you’re devoting to navigating that environment. Compliance is an essential tool for creating systems that reduce a wide range of potential inputs into a simplified space of positive outputs.

Fridge Clip

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.

Defrosting all over my floor. The trash can is there for dumping the icy slush once the drip tray filled up.

I designed a clip to solve this problem. I modeled it in a half hour and it took my Ultimaker a bit more than two to print it. I’m very happy with how it turned out. This clip has an integrated spring and a central rib to optimize the stiffness without adding tons of thickness (i.e. more print time). It attaches to the fridge body with three rivets. For the rivet holes I wrapped my drill in some electrical tape to make sure it didn’t plunge too far into the insulation and damage anything. It was installed in a snap and hopefully will prove a permanent solution to an annoying problem. Continue reading

Scrap Microwave Spot Welder

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.

Why Spot Welders are Useful

insta001

Spot welders are handy to have around the shop. They can tack together wire for quick brazing, and permanently weld sheet metal for durable enclosures. If you want a thorough guide on what you can do with a spot welder, Dan Gelbart has all the answers. I’ve been looking to up my prototyping game and have more freedom to build custom components when off the shelf parts won’t suit. Unfortunately my workshop is in Brooklyn and space is at a premium. I spent a lot of time fabricating structures out of steel wire in school and have found that it’s a good replacement for bent sheet metal and structural framing if you play your cards right. Wire is easy to store in a small shop, doesn’t take much equipment to manipulate, and can hold good tolerances in various dimensions as its behavior is very predictable. You can still find the manual I follow for a lot of my techniques on Amazon. Continue reading
