Using an Arduino Uno along with a Raspberry Pi for control, hacker “HomoFaciens” came up with this clever delta-style robot.

If you were going to make a robot with five servos, many Makers would make a robot arm with them and call it a day. HomoFaciens, however, who is known for making amazing machines with minimal tools and improvised materials, instead made something that seems to be a cross between a delta robot and a Skycam.

His device, called “WinchBot,” uses three winches attached to an equilateral triangle frame to move a slider on a central pivoting square rod. This allows the robot’s 5-axis “hand” to be positioned within the robot’s work area. The servos are then tasked with keeping everything in the correct orientation, as well as opening and closing the gripper as needed.

If you’d like more details than given in the very entertaining video seen here, be sure to check out the project’s write-up.

Tired of buttering your toast in the morning? Well, William Osman has just the solution for you, albeit slightly dangerous and excessive for the task at hand.

For his “extremely violent” machine, Osman used a jigsaw motor to hold the butter and an Arduino-driven linear stepper motor to move the slice of toast back and forth. The robot’s frame, spikes, and mounts are all crafted out of laser-cut wood, and everything is held together by a bunch of zip ties.

I was planning on making a more cohesive user experience. But then I didn’t. The jigsaw trigger was wired to a 12v lead acid battery, and the stepper motor was driven by a motion control driver I built several years ago.

Osman documented his entire build process and shared the end result in the video below. Be sure to also check out his other projects here!

Need a hand? The UFACTORY team has got you covered with the uArm Swift, an open-source robotic assistant for your desktop.

The four-axis uArm Swift is a smaller and sleeker version of the company’s original device from 2014. Based on an Arduino Mega, the robot is capable of lifting 500 grams (1.1 pounds) with a working range of 5 to 32 centimeters (2 to 12.6 inches).

UFACTORY has launched two different models of the consumer-friendly arm on Indiegogo. Whereas the basic model is perfect for beginners and those looking to tinker around with robotics, the Swift Pro is designed for a more experienced Maker crowd with a stronger motor, more precision, and greater versatility. It also boasts position repeatability down to 0.2mm.

With a little programming, the Pro can perform a wide range of tasks from 3D printing to laser engraving to picking up and moving game pieces. You can even create your own actions through the team’s Blockly-based graphical software, uArm Studio, as well as control your Swift either directly from a keyboard-and-mouse setup, by making gestures, or over Bluetooth from the uArm Play mobile app.

The Swift is extendable with three different end-effectors (suction cup, metallic gripper, and universal holder) and a built-in socket for selected Seeed Grove modules. But that’s not all. Attach an OpenMV Cam and the robotic arm can detect faces, colors, and markers.

Using gigantic hands scaled up from a prosthetic design, “XenonJohn” can now hear the sweet sounds of Scotland whenever he wants.

Seeing this invention, you might note to yourself that most instrument-playing robots don’t actually bother to have realistic—if huge, at 171% normal print size—hands attached. Then again, you probably haven’t seen a robot configured to play the bagpipes.

The robot named Ardu McDuino plays the bagpipes, or rather the chanter part that is manipulated with one’s fingers, using actual prosthetic fingers to cover the holes. It also has a less-realistic “thumb” to cover a hole on the back.

Everything is controlled using an Arduino Mega via a bank of opto-isolated MOSFETs, along with solenoids to let it grip the individual air holes for music generation. You can read more about this project on its Instructables page!

Today on In Case You Missed It: Pairing an Arduino with a skateboard produces the Sick Ollie Machine, capable of measuring angular and X-,Y- or Z-axis accelerations to measure who is hitting their tricks the hardest. Courtesy of Josh Sheldon, the ollie machine uses an Arduino beneath the trucks of the board paired with a relay to measure the stats of each trick. Those who are producing truly sick ollies are rewarded with a chime from the attached cowbell.

Meanwhile, over at CERN a set of robot twins have been enlisted to provide live video feeds and environmental measurements for the massive underground complex. The robots, called TIM twins for Train Inspection Monorail, move along a -- you guessed it -- overhead rail that runs throughout the facility in order to monitor stats like oxygen concentration and radiation emissions.

Also, don't forget to check out what happens when a frog is run through Google's Deep Dream project (which is easily the weirdest sentence I've written yet today). As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.

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.

Congratulations to the winner of this year’s Hackaday Prize, Alberto Molina Perez! Inspired by Bruce Lee’s famous water quote, Dtto is a self-reconfigurable robot that can adopt any shape by simply changing the position and connection of its 3D-printed modules.

A coupling mechanism on both ends allows the sections to assemble themselves in various configurations and carry out complex tasks in unison. They can chain together to create a snake-like robot, turn into a wheel, or even form a bridge to get over a gap. Impressively, this is all accomplished autonomously. The goal is that, one day, Dtto’s versatility will enable it to perform rescue missions and explore unknown environments without any human intervention.

As Hackaday notes, each module consists of two boxes, rounded on one side, linked by a bar. One half houses all of the electronics, which includes an Arduino Nano, a Bluetooth chip, an NRF2401+ radio transceiver, two SG92R Tower Pro servos for hinging, and three Tower Pro SG90 micro servos for coupling, while the other leaves space for additional features, such as a camera, microphone and speakers, multiple sensors, actuators, or more batteries.

You can read more about the project on its Hackaday.io page, and be sure to check out its latest demo reel below!

Interactive designer Alexia Léchot has built a delta robot with a ‘personality’ that interacts with humans through iPads. Deltu uses three moving arms, a couple Unity3d applications, and Arduino to play simple mimicking games.

According to Creative Applications:

The system uses two Unity3d applications where the application of the human sends HTTP request to the computer. There is also a Python server that sends the string through the serial to the Arduino which controls the robot.

The other player must precisely copy Deltu’s movements because it “is very demanding.” If not, it might change its mind and will shake its arms in a side-to-side motion that appears to simulate frustration. From there, Deltu leaves the game and opens the camera app instead, snapping selfies and posting them to Instagram.

As you can see in the video below, the robot even takes a few moments to browse the social network’s explore section and follow a new account, as well as choose some tunes on SoundCloud.

Depending on its mood, it plays with the user who is faced with an artificial intelligence simulation, who appreciates the small pleasures of life, sometimes too much. The relationship we have with robots/AI that have been created to enhance our performance, but have become a source of learning, is unique and exciting. The android’s place in ociety has not yet been defined and remains to be determined; for me it is the best source of inspiration.

Intrigued? You can see Deltu in action below, and read more about the project on the Daily Mail.
