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…)
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…)
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.
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.
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…)
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…)
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…)
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!
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.
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…)
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.
