One of my favorite projects in MAKE: Soft Robotics is the Kousa. It’s a soft sensor that uses water power to turn a simple force sensing resistor into a versatile sensor that can pick up squeezing, tapping, and pressing from any angle.Continue reading
After years of building projects, testing designs, writing, and editing, MAKE: Soft Robotics is ready to hit shelves! It’s available on presale from Amazon and is scheduled to go live Dec 23. I can now officially say I’m an O’Reilly author, and that I literally wrote the book on soft robotics.Continue reading
I’ve been playing with origami, lately. Specifically, I’ve been exploring how to simulate, model, and fold origami shapes in ways that could be automated to create useful mechanisms. The system I’ve come up with is designed to fold rip-stop nylon, a material I’ve worked with at both Makani Power and Super-Releaser.
After some experiments with programs designed specifically for generating origami patterns, I found I wasn’t able replicate the patterns I’d prototyped in paper. Since I wanted to start out with a paper prototype, do some bench tests, and move to CAD from there, I needed to consider other options. I also wasn’t able to convert the output into a format that would play with CAD for printing and prototyping the resulting forms. So, I fell back on my old standard: SolidWorks. If you’ve worked with me before or you’re a regular reader, you don’t get any bonus points for guessing I’d find a way to turn this into a SolidWorks project. This video was very helpful for understanding how to think about origami in a SW context.Continue reading
I developed this static mixer design to streamline casting demos. Often times, a casting demo can get bogged down with portioning, mixing, and degassing, especially when you’re trying to have a group of students get hands-on time with the casting materials.Continue reading
Cheap grow lights are great – they’re energy efficient, ubiquitous, and the design pattern of the aluminum-backed PCB for dissipating heat is well chosen. However, unshielded high-output LED’s are a real pain on the eyes.
I bought a set of these grow lights to give the plants in my bedroom a little boost since their window faces a shaded courtyard in the center of my building. Rather than invest in something more expensive or put up with hot pinpoints of light stabbing my eyes every day, I designed a cheap printed diffuser to make the system more hospitable.Continue reading
After testing the Flat-Pack Camera Arm, I was pretty happy with the results. Happy, except for one detail: the joint at the base of the arm would creep down over time. This wasn’t a problem while taking shots of projects at the bench, given how often I’d have to reposition it. The big pain was trying to capture time lapses. The creep was just too noticeable, and it would never stay in place long enough to keep the action of a day’s work in frame.Continue reading
I’ve been experimenting with printed flexures, and wanted to make a simple tensegrity toy to explore the concept. This design (which you can download on Thingiverse) features both printed tension and compression elements that all build together into a slightly bouncy tensegrity sculpture.Continue reading
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.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
