Wink is a low-cost, Arduino-powered pet robot


This bug-like bot enables Makers to easily migrate from graphical style programming to written code. 


Pet rocks were all the rage in the mid-’70s, and then came the Tamagotchi in the ’90s. So what could be the next craze in the current millennium? Pet robots? It’s not a far reach. Robotics has been a disruptive innovation in STEM education, with a growing number of kits being deployed by K-12 educators to teach science and engineering. These easy-to-build and even easier-to-understand sets continue to provide students with a basic overview of programming concepts, with hopes of inspiring more children to pursue STEM disciplines. However, students will eventually need to move on to writing “real world” programming languages like Java, Python, C, and C++. Plum Geek saw this need, and came up with the next logical step to prepare the next wave of hackers, tinkerers and Makers.

Meet Wink — a low-cost, Arduino-based robot that instructs students how to write code, while programming the robot’s behavior as well. The project was originally conceived by a team of Makers who wanted to help transition students from graphical programming to more powerful written code languages. With Wink, students will learn the foundations of the C programming language, which is widely used to control microprocessors used in all manner of robotics, embedded systems, automation, and the growing Internet of Things revolution.

The Wink robot includes a free and open curriculum with lesson plans and guide videos that could be easily adopted at home, in the classroom, and at workshops. Students will train their new pet robot by programming common robotic tasks such as line following, light seeking, barrier detection, and autonomous roaming, while also leaving room for students creative experimentation.

If Wink looks vaguely familiar, that’s because the bug-like bot is the sibling of Plum Geek’s earlier Kickstarter success Ringo. These palm-sized pet robots may be small, but still pack quite a punch. Built around an Arduino Uno (ATmega328) at its core, Wink runs on a fast motor and each motor can be independently driven forward or backward. At full speed, it can zoom across the floor or table in the ‘wink’ of an eye — surely quicker than any pet rock you ever had!

What’s more, the bot is equipped with three sensors on top to measure any light that’s straight ahead and 45 degrees to either side, an infrared barrier headlight tucked under its nose to detect obstacles that stand in its way, four more sensors underneath for high-speed line following and edge detection, as well as a piezo buzzer to emit simple chirps and alarms. Onboard is a rechargeable 240 mAh LiPo, giving you hours of fun and experimentation.

Interested in a new pet robot for your house or classroom? Head over to Wink’s Kickstarter campaign, where its creators have once again stormed right by its initial goal. The first batch of units is expected to ship sometime in January 2016.

Which hardware, languages and APIs are used the most at hackathons?


Devpost ranked the APIs, languages and technologies that student hackers used during the 2014-2015 academic year.


Thanks to the burgeoning Maker Movement, the number of hackathons has surely risen in recent years. The next generation of programmers, engineers and designers all come together for a few sleepless days, fueled by pizza, Red Bull and coffee, to devise new and exciting gadgetry either of their choosing or based on parts provided by one of the sponsors. These weekend-long events organized by and for students are surging in size, scale and frequency, popping up in some of today’s booming tech centers ranging from Silicon Valley to New York. At hackathons, time is a valuable thing. This, of course, means that participants must strive to generate code and piece hardware together as quickly as possible.

11061272_1639114646317502_6597268336542950867_n

Which programming languages are the most popular? What has become the go-to hardware? Which APIs and platforms do people utilize most frequently? This is what Devpost —  formerly known as ChallengePost — sought to find out. In order to accomplish this, the online community and competition platform collected data and ranked the technologies and programming languages that student hackers have turned to the most throughout the 2014-2015 academic year.

Devpost examined project tags from a sample of over 13,000 student hackers who participated in 160 hackathons and submitted 9,898 projects, either in hackathons or on their Devpost portfolios. The technologies tagged in projects include languages, various APIs, frameworks, databases, IDEs, libraries and hardware, among several others. For each category, the company reported the top five tags.

While you can check out the entire report here, we’ve highlighted some of the more interesting findings below.

When it came to mobile platform, the crowd favorite was Android with 38.2% followed by iOS at 22.7% and Windows Phone at a distant 4.9%. As for programming languages and frameworks, HTML and CSS topped the list with JavaScript, Python, Java and C/C++ not far behind. Outside of the top five included PHP, Objective-C, C#, Swift, JSON, Ruby, XML, Ajax, Shell and Processing.

devpost_student_programming1-1024x541

In terms of hardware, the easy-to-use Arduino unsurprisingly found itself atop the leaderboard ahead of Myo, Pebble, Leap Motion and Oculus Rift. Other notables included Raspberry PI (#6), Intel Edison (#7), Particle (#9) and Tessel (#18).

The use of standard libraries and preexisting tools is paramount in getting a project up and running quickly. And so, many developers rely upon popular APIs and SDKs. According to DevPost, the most popular programs used by students included Twilio for messaging, Facebook for social, Venmo for payments, Google Maps for geo, Spotify for music and Unity for gaming. The rankings reveal that Node.js was extremely popular during the academic year, more so than app frameworks like Flask, AngularJS, Ruby on Rails and Django.

These friendship bracelets will introduce more female programmers to the world


Jewelbots is reinventing the classic charm bracelet as a Bluetooth-enabled wearable that will teach girls how to code.


Developers Sara Chipps, Brooke Moreland and Maria Paula Saba have noticed that there is an extreme lack of women in the STEM-related fields. And although research has shown that 75% of girls were interested in such disciplines, a vast majority are choosing not to pursue computer science. In order to help combat this downward trend, the team has designed a new product that they hope will introduce the future generation of female engineers to coding. Unlike other wearable gadgetry on the market today, which track steps, count calories and monitor heart rates, Jewelbots are programmable bracelets that enable its young users to personalize and build their own custom features.

Jewelbots-1-966x644

Originally inspired by the popularity of Minecraft for the predominantly adolescent male crowd, the entrepreneurs wanted to establish a similar environment for girls that would also allow them to explore their creativity and write their own mods.

Makers begin with a simple IFTTT-like statements on an accompanying mobile app. Once they are ready to advance, girls can plug their device into a PC, and using the open source Arduino IDE, customize their bracelets to their liking with sample libraries on the startup’s website. For instance, they can program their jewelry to illuminate with every new Instagram follower, when they receive a text from mom, their favorite TV show is about to start, or even if there is a change in the weather forecast. However, the possibilities are only limited to the imagination of its wearer.

Beyond that, the bands help keep girls stay in touch with their friends. Connected through Bluetooth Low Energy, the bracelets create a mesh network that lets users communicate with other Jewelbots wearers nearby, even without a paired phone or Wi-Fi. The Jewelbots can blink, vibrate and light up to communicate in Morse code. In terms of hardware, each unit is packed with a BLE SoC, a vibration motor, four LEDs, a button and a battery which can be recharged via USB.

“The numbers of women in computer science have actually shrunk since the mid 80s. At the same time, engineering and tech jobs are growing like crazy,” Moreland explains. “We want to inspire a deep curiosity and lasting love for computers and programming. A love that these girls can take with them throughout their careers and lives.”

Wrist

As a way to test their theory, the team launched “Take Your Daughter To Hack.” During these daylong, bi-coastal events, parents and daughters (sons, too) were given the chance to devise wearables using the highly-popular Arduino GEMMA (ATtiny85) as well as a HTML/CSS workshop using Tumblr to make fun and engaging projects together. Safe to say, they were a success!

While its prototypes are currently being finalized, the end product will make its debut at the tail-end of summer, with widespread delivery expected to get underway in March 2016. At that time, the bracelets will come in a variety of colors — including pink, green, lavender, red, garnet, blue, teal, gray and back — and will be just as fashionable as they are fun! Interested? Head over to Jewelbot’s official Kickstarter page, where the New York City-based startup is seeking $30,000.

Roby is an Arduino-based, 3D-printable robotic platform


Young Makers can build their own customized, self-balancing robots as they explore programming and 3D design.


The brainchild of Seattle startup Socially Shaped, Roby is a 3D-printed robotic machine that not only drives on four wheels, but can walk on two. If it falls, it can even pick itself up again with its two arms.

6482a2044aa4d10f707cc2eb39eb241b_original

The open-source robotic platform features a programmable on-board computer along with an Arduino remote controller. Developed as a way to introduce young Makers to programming and basic electronic principles, users can customize a personality for their bot, as well as add new attributes like computer vision, sensors and voice recognition.

“Roby is not just an entertaining robot, it’s a robotic learning platform. When you build Roby you will have an opportunity to learn in a fun and engaging way,” its creators explain.

2e026274872a2c1bc286fcaf0999e590_original

In piecing together one’s very own Roby, Makers will have the unique ability to master programming languages, explore Arduino and Raspberry Pi, acquire rudimentary skills in Linux-based operating systems, and dabble with Wi-Fi and Bluetooth communication. Moreover, a child can leverage 3D printing to put a personal touch on their design.

For its Kickstarter launch, the team has unveiled three Roby kits — Roby Junior, Roby Standard and Roby Genius — each varying in price, capabilities and levels of complexity. What’s nice is that the Maker-friendly platform is also entirely upgradeable, so that a a user can graduate from one stage to the next.

Designed for novices, Roby Junior is an autonomous, RC robot controlled by an Arduino. Aside from the Atmel based board, the kit includes a pair of DC motors, a shield to drive the motors, an ultrasonic sensor to help Roby avoid obstacles and a remote control for enhanced entertainment.

Meanwhile, Roby Standard is an intermediate set for those seeking a little more adventure. The self-balancing bot can walk (well, sort of) on two wheels and is equipped with a pair arms to help it stand up should it fall. Beyond that, it can speed down a driveway in race car-like fashion or be outfitted with a set of tracks for some off-road fun. This Roby, which is a step up from the Junior model, features an Arduino, a custom shield, an ultra-sonic distance sensor, a gyroscope for self-balance, high-grade NEMA17 stepper motors for precision, servo motors for its arms, in addition to a few other electronic components.

It’s always refreshing to see new DIY platforms, such as mBot to LocoRobo, emerge in an effort to introduce children to STEM-related fields. Is Roby right for you? Head over to its Kickstarter campaign, where the Socially Shaped team is seeking $25,000. Shipment is expected to begin in August 2015.

BBC to give out 1 million devices to kids as part of new initiative


BBC launches a UK-wide initiative to inspire the next generation of programmers and engineers.


It’s no secret that the Maker Movement has transcended well beyond the garages and workspaces of a few tinkerers. The phenomenon has proliferated the walls of schools, libraries, museums and retailers, among countless other establishments. Academic institutions and startups, particularly those seen on crowdfunding sites, have developed new projects in hopes of spurring the pursuit of STEM-related fields for the next generation. Maker Faire attendance is also on the rise as thousands of DIYers come together at one of 80 community events spanning across 10 countries. Looking to continue carrying that momentum, BBC has launched a new project — in partnership with over 50 organizations — which is looking to give a personal coding device to every child in year 7 across the country. That’s 1 million free devices in total to students, generally aged between 11 and 13, as part of the campaign they’re calling “Make it Digital.”

make_it_digital

Back in the 1980s, the BBC launched a Computer Literacy Project which aimed to support the learning of computing — at the time a relatively new concept for a vast majority — in schools and the home. This included a commercial partnership with Acorn Computers to produce a microcomputer as the backbone of the initiative: the BBC Micro. While nine models were eventually made with the BBC brand, the phrase “Micro” is usually used colloquially to refer to the first six (Model A, B, B+64, B+128, Master 128, and Master Compact). Well now, the news giant is reimagining its popular 1980s campaign by introducing its successor, the BBC Micro Bit.

Based on a processor which would appear to be an ATmega32U4, the Micro Bit will give students a physical companion in their path to coding competence. While merely a prototype at this point, it will be a standalone, palm-sized device equipped with an LED display and compatible with the Touch Develop, Python and C++ languages.

_81579433_microbit

Young Makers will then be able to create text via a series of lights as well as devise basic games. What’s nice is that the final version of Micro Bit will feature a Bluetooth link and will be able to sync up with other incredibly-popular boards like Arduino, Galileo, Kano and Raspberry Pi, in addition to other Micro Bits.

According to BBC, the Micro Bit will be distributed later this year, most likely the fall. The program was designed as a response to a shortage within the digital industry, given that nearly 1.4 million professionals will be needed over the next five years. BBC is hoping to aid in building the country’s talent pool and arming them with the requisite coding skills through a range of new partnerships and projects.

LocoRobo is an IoT bot inspiring the next generation of Makers


LocoRobo offers a modern, cutting-edge robotics kit and a technology-rigorous learning experience.


Drexel University professor Pramod Abichandani and a team of three undergraduate students have developed LocoRobo, a low-cost robot capable of being wirelessly programmed with minimal to no effort. Born out of his own frustrations with bots, Abichandani aspires to advance programming and robotics education for everyone — from first-graders to experienced Makers — by combining a world-class programming ecosystem with a high-quality device.

blueRobot

Abichandani hopes that educators and students alike will be able to utilize the ATmega32U4 based LocoRobo to increase awareness and excitement around STEM. While younger Makers can wirelessly control their robot through the companion mobile app, experienced developers can use various programming languages.

“We have developed open-source application programming interface (APIs) in C, Python, Matlab and Node.js which will allow you to dive into programming LocoRobo beyond the apps. Using these languages you will realize a higher level of control of the LocoRobo robot. While working with our APIs, you will be exposed to several robotics exercises and concepts including multi-robot motion planning and multi-sensor fusion.

ecosystem

As seen inside the Atmel CES booth, the little WALL-E-like gadget is equipped with two wheels, sensors for eyes and antennas in the form of ears. Recently launched on Indiegogo, the Arduino-compatible LocoRobo comes in two separate models: the LocoBasiX and the LocoXtreme. While each possess the same custom main board, status LEDs, differential drive, ultrasponic sensors, lithium-ion battery and BLE, the LocoXtreme model boasts a number of additional features such as motor encoders, an on-board accelerometer and a gyroscopic sensor for those seeking some more sophisticated movement.

Abichandani hopes that every school throughout America (and the world) will one day have a solid robotics program. And, LocoRobo may be able to make that dream possible.

Rewind: 13 products inspiring the next generation of Makers

With Computer Science Education Week in full swing and the holidays just around the corner, we’ve decided to list some of our favorite creations from this year that are inspiring the next generation of Makers to not only tinker around, but pursue STEM disciplines.

littleBits

Powered by an ATMega32u4 MCU, the MaKey MaKey has been on the scene since Jay Silver successfully funded the project back in 2012, attaining nearly $570,000 in Kickstarter pledges. When a user touches an object that is hooked up to the board via alligator clips, i.e. a banana, a connection is made which sends the computer a keyboard message. In essence, the computer considers MaKey MaKey as a regular keyboard (or mouse), meaning it can work with pretty much all programs and webpages.

Nübi

nubi

Developed by UX design from Slice of LimeNübi aims to teach basic programming skills to kids of any gender. The creation is described by its creator as an Internet-enabled toy that takes the form of a creature who just arrived on our planet and needs to be taught about everything, from colors to music to temperature. The toy is embedded with a series of sensors that enable it to wirelessly communicate like an RFID chip with other devices in its environment, such as a motion detector or light sensor. Kids use an accompanying flower-like wand, equipped with an [Atmel basedArduino-controlled RFID reader, to talk to Nübi.

AERobot

robot-kids-inline1

A group of Harvard University researchers have developed an $11 tool to educate young Makers on the fundamentals of robotics. Dubbed AERobot (short for Affordable Education Robot), its team hopes that it will one day help inspire more kids to explore STEM disciplines. The bot  can move forward and backward on flat surfaces, turn in place in both directions, detect the direction of incoming light, identify distances using infrared light, as well as following lines and edges. With a megaAVR 8-bit MCU as its brains, most of its other electronic parts were assembled with a pick-and-place machine, and to reduce costs some more, used vibration motors for locomotion and omitted chassis. AERobot is equipped with a built-in USB plug that also allows it to be directly inserted into any computer with a USB port.

ArduSat Space Kit

satellite-e1409075991984

Ask any classroom of kids what they want to be when they grow up, and undoubtedly a few imaginative youngsters will answer emphatically with “Astronaut!” With that lofty goal in mind, Spire (formerly Nanosatisfi) launched its ArduSat program to bring space exploration to the classroom. ArduSat is the first open satellite platform that enables the general public to design and run applications, games and experiments in space, while also steering onboard cameras to take pictures on-demand. More specifically, ArduSat is designed to give ordinary people – like students  – the chance to conduct experiments by controlling over 25 different integrated sensors including spectrometers, magnetometers, radiation measurement devices, gyroscopes, accelerometers and thermometers. With its space kit, ArduSat is supplying individual classrooms all of the tools they need to carry out space exploration. Each set contains an Arduino Uno (ATmega328), a series of sensors, LEDs, and other components. By linking the sensors to the Arduino, students can measure levels of temperature, luminosity, and magnetic fields. Currently, more than two dozen schools are using ArduSat, with plenty more to follow.

ScratchDuino
