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
We don’t think we’d want to trust our fire safety to a robot carrying a few ounces of water, but as a demonstration or science project, [Tinker Guru’s] firefighting robot was an entertaining answer to the question: “What do I do with that flame sensor that came in the big box of Arduino sensors I bought from China?” You can see a video of the device below.
You can see, it is a pretty standard two-wheel robot with the drive wheels to the rear and a skid plate up front. There are a flame sensor and a water pump up …read more
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
Motors are not overly complex, but this one is downright simple. Carl Bujega has been working on a motor design that heavily relies on the capabilities of the printed circuit board (PCB) fabrication processes. His talk at the 2018 Hackaday Superconference covers how he built a brushless DC motor and speed controller into a PCB. You can watch the newly published video after the break.
There are two main parts of an electric motor; the stator is stationary while the rotor spins on bearings. Electromagnetic forces are used to cause that spinning action. In this case, Carl has built the …read more
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
Despite being over 25 years old, the original DOOM is still a favorite among gamers and hackers alike. For years now, running the 1993 demonic shooter has been a critical milestone when hacking or reverse engineering a piece of gear, and at this point we’ve seen it run on everything from voting machines to cameras.
But this time around, DOOM isn’t actually running on the device being hacked. Instead, the Roomba 980 that [Rich Whitehouse] has doing his bidding is being used to generate new DOOM levels based on the maps it makes of rooms while going about its business. …read more
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
When [314Reactor] got a robot car kit, he knew he wanted to add some extra things to it. At about the same time he was watching a Star Trek episode that featured exocomps — robots that worked in dangerous areas. He decided to use those fictional devices to inspire his modifications to the car kit. Granted, the fictional robots were intelligent and had a replicator. So you know he won’t make an actual working replica. But then again, the ones on the TV show didn’t have all that either.
A Raspberry Pi runs Tensorflow using the standard camera. This lets …read more
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.
Tony Stark, the fictional lead character in the Iron Man movies, …read more
