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.

These Arduino bots move plants to sunny and shady spots

Friday, August 12th, 2016

What do you do when you want your plants to grow but you lack a green thumb? Give them wheels and the ability to seek out sunny and shady spots on their own. This was media artist Kathleen McDermott has done.

The aptly named Sunbot and Shadebot are robots that help houseplants tour the outside world. Sunbot uses photocell (light) sensors to look for sunny places to rest, while Shadebot employs the same sensors to locate shadowy spots. (more…)

David Cuartielles judges robots at Hebocon Spain and Tokyo

HeboconMadrid_1

Being a dumb and clumsy robot has never been as fun as in the stupid robots competition Hebocon. This competition series is described as “robot contests for the technically ungifted” by its creator Daiju Ishikawa, and encourages anyone to join with no prior knowledge of robotics necessary.

What’s neat is that unlike other awards, Hebocon’s are symbolic as they are usually made out of recycled parts from every robot in the competition!

So far there have been two editions of Hebocon in Spain (Valencia and Makespace Madrid) where our very own David Cuartielles participated as a judge.

Last weekend, Cuartielles was invited to the Hebocon World Championship in Tokyo where he served on the judging panel alongside Nifty’s Dr. Kunio Matsui and an executive from NicoTsuku (a company dedicated to digital communities). The event drew a total of 32 robots from all across the world, including the United States, Hong Kong, Iceland, France, Singapore, Greece, Taiwan and Japan.

The winners were:

Nifty Award: An unusual car with a spinning doll that shot fake banknotes

NicoTsuku Award: A robot with a middle-age man that turned a table upside down (a literal representation of a Japanese colloquial expression that means getting mad)

Arduino/Genuino Award: A crocodile robot made by a 10-year-old that previously participated in Maker Faire Tokyo

The ‘Remote-Controlled Robot’ from Hong Kong won the sumo competition and it was about fooling the opponent by switching the roles of the remote control and the robot.

The little Arduino robot arm that could!

Tuesday, August 2nd, 2016

As its name would suggest, the LittleArm is a mini 3D-printed robot that began as a weekend project. Its creator Gabe Bentz wanted a small arm that was easy to work with, and one that wouldn’t require him to dig deep into his wallet. So, as any Maker would do, he decided to design his own low-cost device.

After showing the LittleArm off, it wasn’t before long that he was approached by some STEM teachers in the area who wondered if the kit was something they could use in their classrooms. Ideally, every student should have one to tinker with, but unfortunately today’s systems tend to be too expensive and quickly loose parts and pieces. This is a problem that LittleArm is looking to solve.

The arm is powered by an Arduino Uno and four identical metal-geared micro servos, while all other mechanical components are 3D-printed. There’s also a modular gripper that’s actuated by a servo along with rigid end-effectors for various tasks. What’s more, a basic GUI enables you to control the arm, its gripper, the speed, as well as use its record function to train the robot to perform a specific task and then watch it play out the sequence.

The entirely open-source gadget comes as a DIY kit that can be purchased or built from scratch. Want one of your own? Check out Bent’z Kickstarter page here, and see the LittleArm in action below (including some of its dance moves).

Grab things with an Arduino robotic gripper

Thursday, June 30th, 2016

Recently-graduated high school students Sam Baumgarten and Graham Hughes have developed a pretty rad robotic gripper with the help of Arduino and 3D printing. The gripper itself consists of three large hobby servos joined to the fingers with a linkage. The underactuated fingers have a force sensor under each contact point, while the control glove is equipped with tiny vibrating motors at the fingertips. This, of course, provides haptic feedback to ensure that the user doesn’t crush anything–the greater the pressure, the stronger the motors vibrate.

Maker adds gesture control to a surgical robotic

Friday, June 17th, 2016

The da Vinci System is one of the most popular surgical robots around, which allows surgeons to perform operations through only a few small incisions. The device works by translating a doctor’s hand movements into smaller, precise movements of tiny instruments inside the patient’s body. As ubiquitous as they may be in hospitals, chances are it’s never been operated quite like this before.

That’s because Julien Schuermans has managed to connect the robotic surgical tool’s hardware up to a LeapMotion controller, making its small forceps gesture-controlled. You can see how it all works in the video below. (more…)

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.
