Hearing live music is certainly enjoyable, but if the musician is using a drum machine, things can eventually get static. To add a bit more spontaneity into this class of robo-musician, Matt Bradshaw has created DrumKid — a handheld, battery-powered unit that uses random numbers to determine the rhythm and sound of a beat. The […]
Remembering to refill water and coffee cups at regular intervals certainly has to be a challenge for restaurant waitstaff, but not for servers at one diner thanks to Mark Wilson’s “TetrisWaterRun” project. Wilson’s device takes the form of a miniature arcade cabinet, with two “players” named H2O and JOE controlling Tetris playfields. As each block […]
The holidays are over and we’re back at work, so it’s time to clean up the house. To get ready for autumn, our amazing dev team has decided to devote an entire week to resolve as many of the open issues on the Arduino IDE repository and related projects (cores, libraries, etc.) as possible. Starting […]
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 by a number of […]
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 […]
