uArm Swift is an open-source robotic assistant for your desktop

Tuesday, January 24th, 2017

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.

Watch an Arduino Mega-based robot play the bagpipes

Tuesday, January 10th, 2017

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. (more…)

QuadBot is a 3D-printable walking robot for everyone

Monday, November 28th, 2016

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. (more…)

Dtto is a 3D-printed, self-configurable modular robot

Monday, November 7th, 2016

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. (more…)

Deltu is a gaming robot with a personality

Tuesday, October 4th, 2016

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.

Robotic fish swims under Arduino control

Thursday, September 29th, 2016

This robotic fish is made from bent PVC pipe and moves its tail for locomotion.

If you’re going to build an underwater vehicle, propeller control is the conventional solution. Eric Dirgahayu, however, created his underwater creature in the form of a fish, complete with a tail that powers it through the water, and pectoral fins that could, in theory, steer it in the correct direction. There is also a ballast tank to adjust its buoyancy. Interestingly, control of this “fish” is accomplished via a TV remote, so the surrounding water would need to be relatively clear. (more…)

Build your own robotic vacuum from scratch

Friday, September 23rd, 2016

This dust buster-based robotic vacuum may or may not work as well as a Roomba.

If you’re fascinated by the idea of a robotic vaccum cleaner to keep you from having to do certain chores, you could buy an iRobot, or you could make your own instead. This particular DIY model uses four motors for locomotion, an Arduino Uno, IR and ultrasonic sensors to avoid obstacles, as well as a (formerly) handheld vacuum cleaner to suck up debris.

The assembly sits on a wooden chassis, and as author B. Aswinth Raj is quick to point out, many variations on this robot could be made. Code is included and fairly short, so whether you’d like to copy this design or improve upon it, the bot should certainly give you some build ideas! (more…)

Build your own robotic arm out of cardboard

Wednesday, September 14th, 2016

From our Chairigami Maker Faire booth furniture to Google VR headsets, we’ve seen various use cases for cardboard. Added to that list is a robotic arm, courtesy of Uladz Mikula.

According to the Maker, the design can be replicated in two hours using Arduino and four servo motors. Aside from the electronics, the project also calls for a piece of hardboard for the base and three clips. (more…)

Robot gets peanut butter everywhere but on the bread

Sunday, August 28th, 2016

What do you do when you’re the Queen of S****y Robots and you’re in the mood for a peanut butter and jelly sandwich? You have a remote-controlled bot make one for you, of course. This is exactly what Simone Giertz set out to do in her latest hilarious project using a pair of robotic arms: one holds a plastic knife for spreading, while the other is puppeteered by her friend, Fiona.

Although this sandwich robot may not be making any PB&Js anytime soon, Giertz’s video will surely have you LOL-ing. Enjoy!

Talk to the (animatronic) hand!

Monday, August 22nd, 2016

Maker Shuang Peng has created a 13 DOF animatronic hand using an Arduino Mega, seven servo motors, and six air cylinders, along with a Leap Motion sensor for control.

As briefly described on his Instructables page:

There are various ways to control the hand. I’ve tried the Leap Motion sensor and the data glove, which catches my motion via Processing. Then the Processing communicate with the Mega via serial. Now, I’m trying to use EMOTIV Insight EEG sensor to control it.
