Robot’s Actions and Our Reactions
» ‎ Hack a Day

If you walk into a dog owner’s home that dog is probably going to make a beeline to see if you are a threat. If you walk into a cat owner’s home, you may see the cat wandering around, if it even chooses to grace you with its presence. For some people, a dog’s direct approach can be nerve-wracking, or even scary depending on their history and relative size of the dog. Still, these domestic animals are easy to empathize with especially if you or your family have a pet. They have faces which can convey curiosity or smug indifference …read more

Robot Arm is a Fast Learner
» ‎ Hack a Day

Not long ago, machines grew their skills when programmers put their noses to the grindstone and mercilessly attacked those 104 keys. Machine learning is turning some of that around by replacing the typing with humans demonstrating the actions they want the robot to perform. Suddenly, a factory line-worker can be a robot trainer. This is not new, but a robot needs thousands of examples before it is ready to make an attempt. A new paper from researchers at the University of California, Berkeley, are adding the ability to infer so robots can perform after witnessing a task just one time. …read more

Control Anything With A Chat Bot
» ‎ Hack a Day

In the world of Internet of Things, it’s easy enough to get something connected to the Internet. But what should you use to communicate with and control it? There are many standards and tools available, but the best choice is always to use the tools you have on hand. [Victor] found himself in this situation, and found that the best way to control an Internet-connected car was to use the Flask server he already had.

The remote controlled car was originally supposed to come with an Arduino, but the microcontroller was missing upon arrival. He had a Raspberry Pi around, …read more

Can This Fire Fighting Robot Take The Heat?
» ‎ Hack a Day

Firefighting is a difficult and dangerous job, which puts humans on the front line to save life and property on a regular basis. It’s a prime candidate for some robot helpers, and [Ivan] has stepped in with a fun build that, while it won’t be serving in your municipal department any time soon, gets us thinking about the possibilities.

It’s a radio controlled robot with an Arduino Uno for the brains. A couple of motor driver boards are used to run four windscreen wiper motors for propulsion. Long before the days of online shopping, the wiper motor was a hacker …read more

Dainty Delta Is About As Small As A Robot Can Be
» ‎ Hack a Day

There’s something mesmerizing about delta robots. Whether they are used at a stately pace for a 3D-printer or going so fast you can barely see them move in a pick and place machine, the way that three rotary actuators can work together to produce motion in three axes is always a treat to watch. Especially with a delta robot as small as this one.

[KarelK16] says this is one of those “just because I can” projects with no real application. And he appears to have been working on it for a while; the video below is from eight years ago. …read more

Kinetic Wire Animatronics Bend It Like Disney
» ‎ Hack a Day

The House of Mouse has been at the forefront of entertainment technology from its very beginnings in an old orange grove in Anaheim. Disney Imagineers invented the first modern animatronics in the 1960s and they’ve been improving the technology ever since, often to the point of being creepy.

But the complicated guts of an animatronic are sometimes too much for smaller characters, so in the spirit of “cheaper, faster, better”, Disney has developed some interesting techniques for animated characters made from wire. Anyone who has ever played with a [Gumby] or other posable wireframe toys knows that eventually, the wire …read more

Rise Of The Unionized Robots
» ‎ Hack a Day

For the first time, a robot has been unionized. This shouldn’t be too surprising as a European Union resolution has already recommended creating a legal status for robots for purposes of liability and a robot has already been made a citizen of one country. Naturally, these have been done either to stimulate discussion before reality catches up or as publicity stunts.

What would reality have to look like before a robot should be given legal status similar to that of a human? For that, we can look to fiction.

Automation is a lofty goal in many industries, but not always straightforward to execute. Welding car bodies in the controlled environment of a production line is relatively straightforward. Maintaining plants in a greenhouse, however, brings certain complexities due to the unpredictable organic processes at play. Hexagrow is a robot that aims to study automation in this area, developed as the final year project of [Mithira Udugama] and team.

You often hear that art imitates life, but sometimes technology does too. Pliant Energy Systems’ Velox robot resembles an underwater creature more than it does a robot because it uses undulating fins to propel itself, as you can see in the video below.

The video shows the beast skating, but also swimming, and walking. It really does look more like a lifeform than a device. According to the company, the robot has excellent static thrust/watt and is resistant to becoming entangled in plants and other debris.

Walking robots come in many forms, and each presents their own unique challenges. Bipedal style locomotion is considered particularly difficult to do well, however designs with more legs offer certain advantages. Hexapods offer the possibility of keeping several legs on the ground while others move, providing a useful degree of stability. [How To Mechatronics] developed this ant robot, which is an excellent example of the form.

The hexapod has as the name suggests, six legs, each of which consist of 3 joints. This necessitates 3 servos per leg, for 18 servos total just for locomotion. Further servos are then used …read more

Soft Rotating Pneumatic Actuators
» ‎ Hack a Day

When we think of pneumatic actuators, we typically consider the standard varieties of pneumatic cylinder, capable of linear motion. These can be referred to as “hard” actuators, made of rigid components and capable of great accuracy and force delivery. However, “soft” actuators have their own complementary abilities – such as being able to handle more delicate tasks and being less likely to injure human operators when used in collaborative operations. The Whitesides Research Group at Harvard University has undertaken significant research in this field, and released a paper covering a novel type of soft pneumatic actuator.

The actuator consists of …read more

Getting people to space is extremely difficult, and while getting robots to space is still pretty challenging, it’s much easier. For that reason, robots and probes have been helping us explore the solar system for decades. Now, though, a robot assistant is on board the ISS to work with the astronauts, and rather than something impersonal like a robot arm, this one has a face, can navigate throughout the ship, and can respond to voice inputs.

Father-and-son team [Wade] and [Ben Wagle] have developed and extensively tested two great walker designs: TrotBot and the brand-new Strider. But that’s not enough: their website details all of their hard-earned practical experience in simulating and building these critters, on scales ranging from LEGO-Technic to garage-filling (YouTube, embedded below). Their Walker ABC’s page alone is full of tremendously deep insight into the problem, and is a must-read.

These mechanisms were designed to be simpler than the Jansen linkage and smoother than the Klann. In particular, when they’re not taking a stroll down a beach, walker feet often need to clear …read more

Smooth Moves from Cheap Motors
» ‎ Hack a Day

Building an electric motor isn’t hard or technically challenging, but these motors have very little in the way of control. A stepper motor is usually employed in applications that need precision, but adding this feature to a motor adds complexity and therefore cost. There is a small $3 stepper motor available, but the downside to this motor is that it’s not exactly the Cadillac of motors, nor was it intended to be. With some coaxing, though, [T-Kuhn] was able to get a lot out of this small, cheap motor.

To test out the motors, [T-Kuhn] built a small robotic arm. …read more

They used to say that robots would take over the jobs too dirty or dangerous for humans. That is exactly what [Joel Sullivan] had in mind when he created this welding robot. [Joel] designed the robot for the OSB industry. No, that’s not a new operating system, it’s short for Oriented Strand Board. An engineered lumber, OSB is made of strands (or chips) of wood. It’s similar to plywood but doesn’t require large thin sheets of lumber. To make a panel of OSB, a 5-inch thick matt of wood chips is mixed with glue and compressed down to 5/16″ at …read more

In a complete surprise, Sony has moved to release the latest version of their robotic dog series, Aibo, in North America. The device is already out in Japan, where there are a number of owner’s clubs that would rival any dedicated kennel club. Thanks to the [Robot Start] team, we now have a glimpse of what goes into making the robotic equivalent of man’s best friend in their teardown of an Aibo ERS-1000.

According to Yoshihiro of Robot Start, Aibo looks to be using a proprietary battery reminiscent of the Handycam camcorders. Those three gold contacts are used for charging …read more

Laser Cut Cardboard Robot Construction Kit Eases Learning And Play
» ‎ Hack a Day

It has never been easier to put a microcontroller and other electronics into a simple project, and that has tremendous learning potential. But when it comes to mechanical build elements like enclosures, frames, and connectors, things haven’t quite kept the same pace. It’s easier to source economical servos, motors, and microcontroller boards than it is to arrange for other robot parts that allow for cheap and accessible customization and experimentation.

That’s where [Andy Forest] comes in with the Laser Cut Cardboard Robot Construction Kit, which started at STEAMLabs, a non-profit community makerspace in Toronto. The design makes modular frames, enclosures, …read more

Mechatronic Hand Mimics Human Anatomy to Achieve Dexterity
» ‎ Hack a Day

Behold the wondrous complexity of the human hand. Twenty-seven bones working in concert with muscles, tendons, and ligaments extending up the forearm to produce a range of motions that gave us everything from stone tools to symphonies. Our hands are what we use to interface with the physical world on a fine level, and it’s understandable that we’d want mechanical versions of ourselves to include hands that were similarly dexterous.

That’s a tall order to fill, but this biomimetic mechatronic hand is a pretty impressive step in that direction. It’s [Will Cogley]’s third-year university design project, which he summarizes in …read more

Most humans take a year to learn their first steps, and they are notoriously clumsy. [Hartvik Line] taught a robotic cat to walk [YouTube link] in less time, but this cat had a couple advantages over a pre-toddler. The first advantage was that it had four legs, while the second came from a machine learning technique called genetic algorithms that surpassed human fine-tuning in two hours. That’s a pretty good benchmark.

Robots that can jump have been seen before, but a robot that jumps all the time is a little different. Salto-1P is a one-legged jumping robot at UC Berkeley, and back in 2017 it demonstrated the ability to hop continuously with enough control to keep itself balanced. Since then it has been taught some new tricks; having moved beyond basic stability it can now jump around and upon things with an impressive degree of control.

Key to doing this is the ability to plant its single foot exactly where it wants, which allows for more complex behaviors such as hopping …read more

An Unmanned Ground Vehicle, Compatable With An Arduino
» ‎ Hack a Day

Building your own robot is something everyone should do, and [Ahmed] has already built a few robots designed to be driven around indoors. An indoor robot is easy, though: you have flat surfaces to roll around on, and the worst-case scenario you have a staircase to worry about. An outdoor robot is something else entirely, which makes this project so spectacular. It’s the M1 Rover, an unmanned ground vehicle, built around the Arduino platform.

The design goal of the M1 Rover isn’t just to be a remote-controlled car that can be driven around indoors. This robot is meant for rough …read more

Some legged robots end up moving with ponderous deliberation, or wavering in unstable-looking jerks. A few unfortunates manage to do both at once. [MusaW]’s 3D Printed Quadruped Robot, on the other hand, moves in rapid motions that manage to look sharp and insect-like instead of unstable. Based on an earlier design he made for a 3D printable quadruped frame, [MusaW] has now released this step-by-step guide for building your own version.

For many of us, our first robots, or technical projects, were flimsy ordeals built with cardboard, duct tape, and high hopes. Most of us grow past that scene, and we learn to work supplies which require more than a pair of kitchen scissors. Researchers at Carnegie Mellon University and Iowa State University have made a material which goes beyond durable, it can heal itself when wounded. To a small robot, a standard hole puncher is a dire assailant, but the little guy in the video after the break keeps hopping around despite a couple of new piercings.

[Dennis] aims to make robotic control a more intuitive affair by ditching joysticks and buttons, and using wireless gesture controls in their place. What’s curious is that there isn’t an accelerometer or gyro anywhere to be seen in his Palm Power! project.

The gesture sensing consists not of a fancy IMU, but of two potentiometers (one for each axis) with offset weights attached to the shafts. When the hand tilts, the weights turn the shafts of the pots, and the resulting readings are turned into motion commands and sent over Bluetooth. The design certainly has a what-you-see-is-what-you-get aspect to it, …read more

Robot Rovers of the Early Space Race
» ‎ Hack a Day

In the early 1970s, the American space program was at a high point, having placed astronauts upon the surface of the moon while their Soviet competitors had not taken them beyond an Earth orbit. It is however a simplistic view to take this as meaning that NASA had the lead in all aspects of space exploration, because while Russians had not walked the surface of our satellite they had achieved a less glamorous feat of lunar exploration that the Americans had not. The first Lunokhod wheeled rover had reached the lunar surface and explored it under the control of earth-bound …read more

Learn Programming From Ants
» ‎ Hack a Day

Humans and insects think on a different scale, but entomologists study the behavior of these little organisms, so they’re not a complete mystery. There isn’t much intelligence in a single ant or a cubic millimeter of gray matter, but when they all start acting together, you get something greater than the sum of the parts. It is easy to fall into the trap of putting all the intelligence or programming into a single box since that’s how we function. Comparatively, itty-bitty brains, like microcontrollers and single-board computers are inexpensive and plentiful. Enter swarm mentality, and new tasks become possible.

Balloons and Bubbles Make for Kid-Friendly Robot Deathmatch
» ‎ Hack a Day

Because nothing says “fun for kids” like barbed wire and hypodermic needles, here’s an interactive real-world game that everyone can enjoy. Think of it as a kinder, gentler version of Robot Wars, where the object of the game is to pop the balloon on the other player’s robot before yours get popped. Sounds simple, but the simple games are often the most engaging, and that sure seems to be the case here.

Rubik’s Robot So Fast It Looks Like a Glitch in the Matrix

From Ferraris to F-16s, some things just look fast. This Rubik’s Cube solving robot not only looks fast, it is fast: it solved a standard cube in 380 milliseconds. Blink during the video below and you’ll miss it — even on the high-speed we had trouble keeping track of the number of moves this solution took. It looked like about 20.

Event: Chaos Communication Congress 22th (22C3) 2005
Abstract: In this talk, several examples of cutting-edge research in robotics will be presented, and their implications for the future of robotics will be discussed. Robots will play an increasingly important role in the development of Artificial Intelligence. Many researchers are convinced that for machines to become truly intelligent, they will need to be embodied. Contemporary research in intelligent robotics does not only draw inspiration from biology and psychology, but also provides these disciplines with the means to test hypotheses by using robots as research tools. Outside the lab, the main market today for robots is moving away from industry robots to the home, with robotic companions being developed for entertainment purposes. As hardware costs are getting smaller and smaller, the same development that happened several years ago with personal computers can now be applied to personal robots. A new trend is to modify existing commercially available robots and add new functionalities (also called `robot hacking'). These different approaches will be presented, and their implications for the future of robotics will be discussed.
