Soccer Playing Robots Score On Human Goalie!

Soccer robot scores on humans

Did you know there’s a rather large community dedicated to making robots that can play soccer? Did you know they’re getting pretty good?

RoboCup is an international robotics competition held annually, first founded in 1997. The goal first and foremost is to promote robotics and AI research — and to do so, they decided to make the competition something that is publicly appealing — Why not one of the most popular sports around? The official goal of the project is to have a team of autonomous humanoid based robot players beat the most recent winning team of the World Cup, complying with the official rules of FIFA. This year, the RoboCup coincided with the real World Cup, and was hosted in Brazil.

There are several categories in RoboCup with various types of robots, and the mid-size team did pretty well this year.

Arguably, this is the most exciting game of all, because it gives a sense of what the current state-of-the-art in robotic soccer is, and how it stacks up to a team of moderately talented squishy bipeds.

We guess that’s a nice way of saying “non-professional soccer players”. Regardless though, they SCORED!

New Round Of Astronaut Or Not: Too Cool For Kickstarter

astronaut-or-not-round3-results

Round 3 of Community Voting has drawn to a close. This time around we had nearly 60,000 votes for 420 projects! The first voter lottery drawing didn’t turn up a winner, but on Friday we ended up giving away the bench supply. We’ll cover the projects with the top votes in just a moment, but first let’s take a look at the voter lottery prize for the new round.

You must vote at least once in this new round to be eligible for the voter lottery on Friday!

voter-lottery-4-prizes

We’ve got so many prizes in the package for the fourth round of Astronaut or Not that we’re just showing you a few in this image.

On Friday morning we’ll be drawing a random number and checking it against the Hacker profiles on Hackaday.io. If that person has voted in this current round, they win. If not, they’ll be kicking themselves (emptyhandedly) for not taking part in the festivities.

This week’s prize package includes:

Now onto the results:

Automated Judging Of Hackaday Prize Entries

cock

We have some of the Internet’s hacking elite judging The Hackaday Prize, and that means they can’t enter any projects into the prize. All the better for everyone else, we suppose. One of the judges, [Sprite_tm], is a resourceful guy and when it comes to judging the entries for The Hackaday Prize, he’s going to do what comes naturally to him: build a machine to automate the task.

[Sprite]’s plan for the JudgeTron 9001 is to use neural networks embedded in biological specimens to do the judging for him. Honestly, we really appreciate the effort he put in to this; biohacking is really in vogue right now, and we do love the classic throwback to the AI renaissance here. It certainly doesn’t hurt that he’s using a Raspberry Pi and an Arduino for this project, either.

Grabbing a touchscreen LCD and a few other parts out of his junk drawer, [Sprite] quickly whipped up a project that would display entries to The Hackaday Prize to the biologically embedded neural nets. These nets needed a little bit of encouragement to select winning entries, so a ‘feed’ back mechanism was laser cut out of acrylic, mounted to a servo, and filled with positive reinforcement.

The software running on the Pi crawls through the list of entries to The Hackaday Prize, extracting images from each one. The plan was for the biological neural nets to select winning entries and be rewarded via the feedback mechanism. These neural nets proved to be very sensitive to the sound of the servo gears of the feedback mechanism, and [Sprite]’s attempt at finding a winning entry with his creation has so far proved unsuccessful. Still, there’s a video of it in action, you can check that out below.

Ask Hackaday: What Can Save RadioShack?

The news for RadioShack is not good. The retail chain that we hackers hold near and dear to our hearts is in financial trouble, and could go under next year.  With just 64 million in cash on hand, it literally does not have enough capital to close the 1,100 stores it planned to in March of this year.

On May 27th, 2011, we asked you what RadioShack could do to cater to our community. They listened. Most of their retail stores now carry an assortment of Arduino shields, the under appreciated Parallax (why?), and even El Wire. Thanks to you. You made this happen.

Today, we are asking you again. But not for what RadioShack can do better. We’re asking what they can do to survive. To live. It makes no sense for RadioShack to compete in the brutal cell phone/tablet market, and makes every bit of sense for them take advantage of the rapidly growing hacker/builder/maker what-ever-you-want-to-call-us community. Let’s face it. We’re everywhere and our numbers are growing. From 3D printers to drones, the evidence is undeniable.

With 5,000 retail stores across the USA, they are in a perfect position to change their business model to a hacker friendly one. Imagine a RadioShack down the road  that stocked PICs, ARMs, Atmels, stepper motors, drivers, sensors, filament….like a Sparkfun retail store. Imagine the ability to just drive a few miles and buy whatever you needed. Would you pay a premium? Would you pay a little extra to have it now? I bet you would.

Now it’s time to speak up. Let your voices be heard. Let’s get the attention of the RadioShack board. You’ve done it before. It’s time to do it again. Hackers unite!

 

Pokáde: Twitch Plays Pokemon, Reborn On Vintage Hardware

poke Early this year, Twitch Plays Pokemon, a webstream of tens of thousands of people playing the same game of Pokemon via web chat. It was certainly an interesting sociological phenomenon, but as in any system where thousands of people try to do a single thing, progress was exceedingly slow at points. This was compounded by the fact the Twitch stream delayed the chat by about 30 seconds.

At the time, there was some talk about setting up an alternative to the emulator-based Twitch stream. Ideas were floated, but until now, no one has yet come up with a workable solution. Now we have Pokáde: real Pokemon games (Red and Blue) running on real hardware (two Super Game Boys, two super Nintendos, and two Game Genies), streamed live to the Internet with an IRC-like chat function.

Simply for the ease of capturing the video of the stream, [Johannes], the guy behind all of this, is using a pair of Super Nintendos and Super Game Boys connected to USB video capture dongles. The Super Game Boys are modded to enable trading between the Red and Blue versions of the game, and controls are handled with a USB connection to the PC running the server.

Anyone can play the game, simply by going to the Pokáde Chat, entering the chat, and clicking on random buttons on the brick Game Boy GUI. The game ROMs have been slightly modified to disable the option of starting a new game, but this is still the classic Twitch Plays Pokemon experience: people all around the globe mashing buttons and creating a religion around a fossil pokemon.

Creepy Cat Eyes With A Microsoft Kinect

F8X0VISHV3Q1HLI.LARGE

Ever feel like someone is watching you? Like, somewhere in the back of your mind, you can feel the peering eyes of something glancing at you? Tapping into that paranoia, is this Computer Science graduate project that was created during a “Tangible Interactive Computing” class at the University of Maryland by two bright young students named [Josh] and [Richard], with the help of HCIL hackerspace.

Their Professor [Dr. Jon Froehlich] wanted the students to ‘seamlessly couple the dual worlds of bits and atoms’ and create something that would ‘explore the materiality of interactive computing.’ And this relatively simple idea does just that, guaranteeing some good reactions. 

As you’ve probably gathered from the title, this project uses a Microsoft Kinect to track the movement of nearby people. The output is then translated into actionable controls of the mounted eyeballs producing a creepy vibe radiating out from the feline, robot poster.

The Fridge Hacking Guide By BrewPi

brewpi-fridge-conversion-51

The team behind BrewPi are at it again! This time they have created an online guide showing how to convert a min-fridge into a Raspberry Pi & Arduino controlled fermentation chamber. In it, they describe 3 possible options:

  • Option 1: Make a simple switched power cord, without hacking into the fridge electronics.
  • Option 2: Make a switched power cord, but also override or remove the thermostat.
  • Option 3: Rip out the thermostat and fully integrate the SSRs into your fridge (which is what [Koen] and [Elco] did).

First things first though. They had to clean the fridge. And depending on where they got it or how long it has been unplugged for, the inside might have been pretty rank and disgusting from mold growing out of every corner. This took a good hour or so to clean properly lest the brewing process get infected with external grossness. This is all worth it because a well-controlled fermentation chamber results in a superior batch of beer.

They put their laser cut case on top of the fridge, holding an LCD, Raspberry Pi, Arduino and the BrewPi Arduino shield. The Arduino reads the temperature sensors inside the fridge, the beer and the ambient temperature. Then it controls the SSRs they added to switch the compressor and a heater. Then, the cables were routed through the fridge and take control of the compressor.
