What has a dozen servos, a WiFi camera, and an Arduino Mega for a brain? Nevon Projects’ snake-bot, of course! This impressive robot uses a total of 12 servos for locomotion and can travel across a variety of surfaces under the control of Android app, or autonomously via a sensor mounted to a smaller servo […]
To help a patient in his country with a congenital limb deficiency, Buzi Nguyen has designed a 3D-printed transhumeral — above the elbow — prosthesis prototype. The device features 10 degrees of freedom, including independent control of four fingers and a thumb, along with movement capabilities for the wrist and forearm. The prosthesis is powered […]
As described in this project’s write-up, “The brachistochrone curve is a classic physics problem, that derives the fastest path between two points A and B which are at different elevations.” In other words, if you have a ramp leading down to another point, what’s the quickest route? Intuitively—and incorrectly—you might think this is a straight […]
Learning about how computers work and coding skills will be important for future generations, and if you’d like to get your kids started on this task—potentially before they can even read—the Ifs present an exciting new option. The Ifs are a series of four character blocks each with their own abilities, such as reproducing sound, […]
Servo motors form the basis of many Arduino projects, but few use them in as interesting a manner as Doug Domke’s piece of electronic art. The device features 36 servo motors arranged on a pegboard to produce various patterns, and can even be used in an interactive mode where it follows a person’s hand around […]
Hydroponics seems like a great way to get fresh vegetables at a cheap price, but as Scott Paterson and Max Knight found out, doing this type of gardening well can take a lot of work. To help take the guesswork and hassle out of the process, the duo has created HydroBot — an automated garden […]
Gray Eldritch (AKA The Technomanc3r) has been working on a robotic hand for some time now, and has settled (so far) on a design with three independent servo-actuated fingers and a thumb. He’s also implemented a wrist assembly to rotate it back and forth, with an Arduino Uno hidden inside for an entirely self-contained gripper […]
Steven Goodwin wrote a JavaScript game called Space Bounce where a character in a space suit has to jump from one side of a mine shaft to another, collecting roughly star-shaped objects, while avoiding spikes. It’s a simple yet rather entertaining game, and since there’s really only one type of interaction (jumping) he decided to […]
Consider the game of chess. It’s a game that flexes one’s “mental muscles” rather than relying on brute strength, but if you don’t have the ability to actually move the pieces, things get a bit more challenging. If you’re playing against another human opponent, he or she could move for you based on what you […]
If you’ve ever seen a delta 3D printer work, you’ve certainly been amazed at the careful coordination of three motors to accurate position a carriage. While impressive in this role, delta robots can be used for much more, from laser engraving, to pick-and-place operations, to automated phone testing, or even playing the piano. To make […]
