Human brains evolved to pay extra attention to anything that resembles a face. (Scientific term: “facial pareidolia”) [Rongzhong Li] built a robot sensor array with multiple emitters and receivers augmenting a Raspberry Pi camera in the center. When he looked at his sensor array, he saw the face of a cat looking back at him. This started his years-long Petoi OpenCat project to build a feline-inspired body to go with the face.

While the name of the project signals [Rhongzhong]’s eventual intention, he has yet to release project details to the open-source community. But by reading his project page and scrutinizing his YouTube videos (a recent one is embedded below) we can decipher some details. Motion comes via hobby remote-control servos orchestrated by an Arduino. Higher-level functions such as awareness of environment and Alexa integration are handled by a Raspberry Pi 3.

The secret (for now) sauce are the mechanical parts that tie them all together. From impact-absorption spring integrated into the upper leg to how its wrists/ankles articulate. [Rongzhong] believes the current iteration is far too difficult to build and he wants to simplify construction before release. And while we don’t have much information on the software, the sensor array that started it all implies some level of sensor fusion capabilities.

We’ve seen lots of robotic pets, and for some reason there have been far more robotic dogs than cats. Inspiration can come from Boston Dynamics, from Dr. Who, or from… Halloween? We think the lack of cat representation is a missed opportunity for robotic pets. After all, if a robot cat’s voice recognition module fails and a command is ignored… that’s not a bug, it’s a feature of being a cat.

Up until the present day, if you need butter, you simply ask another human to “pass the butter,” leading to minor inconvenience and awkwardness. Engineering students in Brussels have come up with a novel solution: a robot that brings the butter to you!

The robot, inspired by Rick and Morty’s Butter Bot, is powered by an Arduino Uno and summoned to hungry humans via an infrared remote control.

When the signal detected by onboard IR sensors, the robot moves over using continuous-rotation modded servos, then flips its cap-like lid to reveal the butter inside.

Want a Butbot of your own? You can find the build process and code in the student team’s write-up here.

If you’re familiar with the Segway or other vehicles that balance in what is known as an “inverted pendulum” configuration, you may think that while interesting, creating something similar would be too complicated or out of your budget. Though perhaps still not simple, Joop Brokking takes you through his design for this type of bot in the video seen here, making it accessible if you’d like to build your own.

The robot, which will cost about $80 in parts, uses two stepper motors for greater movement precision than could be had with normal DC models, and employs an Arduino Pro Mini, along with an MPU-6050 accelerometer/gyroscope for control. It can be driven around by a Wii U-style nunchuck, which transmits to the robot via an Arduino Uno and wireless transceiver module.

You can find more info and product links for this project on Brokking.net.

Whether you choose to control this vehicle with your mind or a joystick, the camera mounted on it will give you a new view of the world.

Maker “Imetomi” was inspired to create a tracked robot after he was able to salvage a camera off of a cheap drone. This became the basis of his FPV setup, which he fitted onto a little tracked vehicle. Although this would have been enough for most people, in addition to building a joystick-based controller, he also made it work with a brainwave headset.

Imetomi now has something that he can drive around virtually, spying on passersby, as long as it stays within the VR transmitter’s 50-meter range. Be sure to check out the video below, where the small bot shows of its impressive all-terrain capabilities, and read his Instructables write-up here.

If you think building a walking robot is impossible, perhaps this little guy will change your mind!

With platforms like the various flavors of Arduino, robotics has become accessible for many more people. Walking robots, however, can still be challenging. Especially when it comes to electronics and programming, one has some fairly complicated mechanisms to figure out. Perhaps none is more frustrating than four-legged walkers, as they seem very stable, but that all changes when one foot is removed from the ground.

QuadBot aims to change this with an Arduino-compatible robot that, with clever cutouts for servo motors and plug-in headers on its main board, should be fairly easy to set up, yet capable of being expanded as needed.

The 3D-printable, open-source bot is designed for Makers of any skill level. It works right out of the box and can be programmed using graphical blocks, ideal for beginners. Every aspect of QuadBot can be customized and modified, though, from the 3D design down to a single line of C++ code, opening it up to more advanced users as well.

QuadBot was made for you to do real deal robotics. This means that you learn coding techniques that are scalable to bigger and better projects, rather than an oversimplified and limited alternative (such as Lego Mindstorms). A robotics platform that sets up young and experienced Makers like this has not existed until right now.

QuadBot doesn’t just walk either, it can dance, light up, and with sensors, can follow you, avoid obstacles, and even play songs. The project is the brainchild of Jack Scott-Reeve and Josh Elijah, who graduated with master’s degrees from the University of Manchester’s School of Electrical and Electronic Engineering.

Interested? Head over to Scott-Reeve, Elijah and the team’s Kickstarter page to learn more or back QuadBot for yourself!

This IOT project started out serious, then I kept thinking of funny things I wanted to make it do. The only way I could think to present it was a corny infomercial style video. It talks, sends you an email when its full, and I made an accompanying Android App for more control over its functionality.

Creative Mornings is a series of talks given by creative types all over the world and recorded for everyone to see online.

Last May, 22-year-old Nerea de la Riva Iriepa, one of the worlds most promising young talents in Robotics gave an inspiring talk about her journey in the world of robotics, her discovery of Arduino, how to work in team and also how to deal with a male-dominated robot world.

She is currently student of Electronic Communications at the University of Alcalá in Madrid and also an intern at Arduino in Malmö where she is creating educational content for beginners and finding ways to make coding easier for young users.

The world of robots is an interesting place, and it’s an even better place for children to get started in electronics. To that end, [Richard Albritton] has created a low-cost, open source robotics platform called the Hack-E-Bot specifically tailored to make it as easy as possible to get started.

The goals for the robot kit were to spark curiosity for electronics and programming, to be easy to assemble and program, to be scalable, and to be as easy on the wallet as possible. This was accomplished by using the familiar Arduino microcontroller on an intuitive platform. The robot uses an ultrasonic rangefinder to navigate as well, and can support a wide range of other sensors. The kit comes in at just under $50, making it a great option for an entry-level robot.

The project is currently seeking crowd funding and [Richard] is also seeking educators to get involved. Currently the only kits available are at fairs and other conventions but they should be able to start producing them in greater quantities in the future. The Arduino libraries are a work in progress but they are available on the project site, as well as several instructional videos and other information about the project.

Last March  RS Components, in collaboration with RobotChallenge, launched the Hack the Arduino Robot competition.

Jacob Glueck submitted a great hack for the Arduino Robot:

“A couple of years ago, I built an Arduino-powered shirt-folding machine which folds clothes. Using the Arduino robot from the RobotChallenge, I will build a device to remove folded clothes from the machine and to stack them. My idea is special because it will involve two Arduinos (the Arduino Uno in the shirt folder, and the Arduino Robot) which will have to communicate, and because it will be very useful. The robot will solve the real life problem of laundry folding by making the task easier and faster and by doing so nicely; the robot will use a custom-designed gripper to transport garments while keeping them perfectly folded.”

On his blog you can look at the pictures of the construction  phase , and below watch the video of the final project:

There's a new kid on the Arduino block, and it's called the Arduino Robot. Launched yesterday at Maker Faire Bay Area, it's the company's first product that extends beyond single microcontroller boards. The Roomba-like design, which we first saw in November 2011, is the result of a collaboration with Complubot. It consists of two circular boards, each equipped with Atmel's ubiquitous ATmega32u4 and connected via ribbon cable.

The bottom board is home to four AA batteries (NiMH), a pair of motors and wheels, a power connector and switch plus some infrared sensors. By default it's programmed to drive the motors and manage power. The top board features a color LCD, a microSD card slot, an EEPROM, a speaker, a compass, a knob plus some buttons and LEDs. It's programmed to control the display and handle I/O. Everything fits inside a space that's about 10cm high and 19cm in diameter.

Pre-soldered connectors and prototyping areas on each board make it easier to customize the robot platform with additional sensors and electronics. It even comes with eleven step-by-step projects and a helpful GUI right out of the box. The Arduino Robot is now on sale at the Maker Faire for $275 and will be available online in July. Take a look at our gallery below and watch our video interview with Arduino founder Massimo Banzi after the break.
