Project Aslan is a 3D-printed robotic sign language translator

Monday, August 21st, 2017

With the lack of people capable of turning written or spoken words into sign language in Belgium, University of Antwerp masters students Guy Fierens, Stijn Huys, and Jasper Slaets have decided to do something about it. They built a robot known as Aslan, or Antwerp’s Sign Language Actuating Node, that can translate text into finger-spelled letters and numbers.

Project Aslan–now in the form of a single robotic arm and hand–is made from 25 3D-printed parts and uses an Arduino Due, 16 servos, and three motor controllers. Because of its 3D-printed nature and the availability of other components used, the low-cost design will be able to be produced locally.

The robot works by receiving information from a local network, and checking for updated sign languages from all over the world. Users connected to the network can send messages, which then activate the hand, elbow, and finger joints to process the messages. (more…)

Ball-on-plate machine uses touchscreen position sensing

Friday, July 14th, 2017

Redditor “xmajor9x” has spent several weeks building a three-legged machine to balance a metal ball on top of a plate. The device uses three servos attached to a rectangular surface with linkages that translate servo position into linear displacement of the table. This allows it to keep the ball centered, or rotate around the perimeter in a circle or square pattern.

An Arduino Due controls the ball using a PID loop, and the ball’s position is sensed not by an external camera, but by the top “plate,” which is actually made out of a resistive touchscreen. Although this adds a very unique element, it means that the ball on top must be quite heavy to be reliably tracked, and its creator is considering switching to a computer vision system in the future.

Be sure to check out the project’s GitHub page for code and more info on the build! (more…)

Building an Arduino-controlled single-pixel scanner

Wednesday, July 12th, 2017

If you’ve seen color sensors such as the TCS34725,  you may have considered them for projects that can pick out one colored object over another. On the other hand, if you were to take one of these sensors, mount them to an Arduino-driven plotter, and then take readings in an X/Y plane, you’d have all the elements needed for a simple single-pixel scanner.

In the video seen below, Kerry D. Wong does just this using his hacked HP 7044A plotter to scan a picture, recording RGB color values in a 128 x 128 grid. As the device scans, the Arduino Due used for control passes these values to a computer, which assembles them together into a low-resolution image. (more…)

Smartwatch convenience ‘moves’ to the next level

Tuesday, May 9th, 2017

To address the limitations of today’s fixed-face watches, researchers have come up with an actuated smartphone concept that physically moves itself using an Arduino Due, Bluetooth and several motors.

Receiving Internet notifications has gone from using a computer, to checking them on your smartphone, to now simply seeing them come in on your wearable device. On the other hand, you still have to rotate your wrist into the right position to see the screen. Worse yet, if you want to show others what is on your wrist, you may even have to twist your arm awkwardly.

Fortunately, there is a possible solution to this scourge in the form of Cito, which bills itself as “An Actuated Smartwatch for Extended Interactions.” This design can move in five different directions–rotates, hinges, translates, orbits and rises–potentially making viewing more convenient, or even providing haptic feedback. Prototype electronics are housed inside a control box on the upper arm, but presumably would become much smaller in a production version. (more…)

M2 by Macchina joins AtHeart!

M2 by Macchina

We’re excited to announce the latest member of Arduino’s AtHeart program, MacchinaNow live on Kickstarter, M2 is an open-source, versatile development platform for hacking and customizing cars.

M2’s two-part design is compact, modular, wirelessly connectable, and based on the popular Arduino Due. It consists of a processor board with a SAM3X8E Cortex-M3 MCU, a USB port, some LEDs, an SD card slot, and built-in EEPROM, as well as an interface board with two channels of CAN, two channels of LIN/K-LINE, a J1850 VPW/PWM, and even a single-wire (GMLAN) interface.

The tiny device (56.4mm x 40.6mm x 15.7mm) can be wired under the hood for a more permanent installation or plugged into the OBD2 port, enabling you to do virtually anything with your vehicle’s software.


Macchina has partnered with Arduino, Digi and Digi-Key to develop M2, and believes that its highly-adaptable hardware will most benefit hot rodders, mechanics, students, security researchers, and entrepreneurs by providing them access to the inner workings of their rides.

M2 accommodates a wide variety of wireless options thanks to its Digi XBee form-factor socket, enabling you to easily connect your car to the Internet, smartphone, satellites, or the cloud using BLE, WiFi, GSM, LTE, and other modules.

The platform can be programmed using the latest Arduino IDE, and is compatible with a number of software packages. Moreover, given its open-source nature, potential applications are bounded only by the collective imagination of the coding community. (more…)

Roast coffee to perfection with an Arduino and Android app

Monday, November 14th, 2016

After winning the South African National Barista Championship in 2009, Neil Maree decided to actually start a company to make coffee roasting equipment. Genio was the result, and after some work, his machines can now roast coffee to perfection using recipe input via an Android app.

Once instructions are transferred, a heavily modified Arduino Due controls the roaster depending on user preferences. Maree first tried an analog solution, then used a PLC before deciding that the Arduino was what he needed. (more…)

Smartwatch prototype turns your wrist into a joystick

Monday, October 17th, 2016

Although smartwatches were designed to be an easy-to-use alternative for your smartphone, interacting with their touchscreens still requires your opposite hand to be free. So what do you do when you’re carrying a bag of groceries or holding onto a bus handle?

This is the problem a Dartmouth-led team set out to solve with WristWhirl, a smartwatch prototype that uses the wrist wearing the device as a joystick to perform common touchscreen gestures with one-handed continuous input, while freeing up the other hand for other tasks.

WristWhirl was built using a two-inch TFT display and a plastic watch strap equipped with a dozen infrared proximity sensors and a piezo vibration sensor, which is connected to an Arduino Due board. Commands are then made by moving the hand as if it were operating a joystick, while a finger pinch turns the sensors on/off to indicate the start or end of a gesture.

Scubo is an omnidirectional robot for underwater exploration

Monday, June 13th, 2016

A team from ETH Zurich has created an incredible submersible robot called Scubo as a way to scan entire coral reefs. Equipped with six onboard webcams, the omnidirectional device is capable of exploring the deep sea from every angle. What’s more, users can take a virtual dive by throwing on a pair of VR glasses to make it feel as if they’re swimming with marine life.

Scubo consists of an Arduino Due for hard real-time tasks, an Intel NUC for high-performance calculation, an IMU, and a pressure sensor — all housed inside a carbon cuboid. Eight thrusters are symmetrically mounted to the outside, one at each corner, while a tube goes through the box to ensure proper water flow and to keep the electronics cool. The system is neutrally buoyed and weight in the form of screws can be added to the thruster arms to adjust buoyancy and the center of gravity.

How to turn data into cocktails!

Data Cocktail_web02

Data Cocktail is a device which translates in a tasty way the Twitter activity and running on Arduino Due and Arduino Pro Mini. When you want a cocktail, the machine will look for the five latest messages around the world quoting one of the available ingredients. These messages define the drink composition and Data Cocktail not only provides a unique kind of drink, but it also prints the cocktail’s recipe along with the corresponding tweets.
Once the cocktail mix is done, Data Cocktail thanks the tweeters who have helped at making the recipe, without knowing it. Check the video below to see how it works:

Data Cocktail was created in a workshop held at Stereolux in Nantes by Clément Gault, founder and interaction designer at Koi Koi.

He made it using Processing and Arduino:

A first application, developed in Processing, pilots the device. The requests are performed using the Twitter4J library, then the application processes the data and controls the device, i.e. the robot, the solenoid valves and the light. The robot itself is based on a modified Zumo frame, an Arduino Pro, a Motor Shield and a Bluetooth module. The solenoid valves and the LEDs are controlled by an Arduino Due connected via USB. The impression is realized by Automator.

To prepare a cocktail, the machine can take up to a minute and may provide up to 6 different ingredients!

Making Space Accessible to Students with U of M Satellite

Friday, April 3rd, 2015


The U of M Satellite project started in 2010 as a student group at the University of Manitoba with the goal of building a nano satellite (10 x 10 x 34 cm) and make space accessible to the public. We got in touch with Ahmad Byagowi, team lead of the project, who teaches robotics in the same university. Ahmad told us that U of M Satellite became soon very popular, in fact  more than 300 students joined the group. In the first iteration the satellite’s goal was studying a micro animal (about 1 mm) called tardigrades and see its behaviour in space. The second iteration started in 2012, the same year of the launch of the Arduino Due and that’s why they designed everything based on it.

We had a nice talk with Ahmad and asked a bit more about the project. (more…)
