Tick Tock

Wednesday, September 14th, 2011

No longer will teams have to stare at a giant analog clock above the referee, we’ve gone digital!

The Sixth Annual Combots Cup is approaching, and with it some new time keeping widgets for the spectators as well as the drivers.

Here’s a peak at what I’ve been working on:

Those are three 7-Segment Display Big Digit Driver kits from Evil Mad Science!

The plan is to remove the decimal points and use them as the colon in the digital clock, e.g. “3:00″.

My experience with the big 7-segment displays has been overwhelmingly positive. They were easy to assemble, all the soldering instructions were clear, and they were easily daisy-chained together. Also, they’re built to plug right into an Arduino (the grey ribbon cable in the picture above)! It’s still to be seen if they are bright enough to be seen inside the combat arena, especially given all the bright lights that are already inside.

Ideally, the giant displays will be put inside the arena for the crowd to be able to see how much time is left in each fight. How we’ll prevent them from getting trashed by some robot is yet to be determined. At the moment they are protected by wishful thinking, hopes, dreams, and rainbows. Unfortunately robots like Last Rites scoff at such things.

I’m also trying to build clocks for each team, so that the robot driver can do a quick glance and see how much time is remaining. I’m attempting to get these 2.3″ 7-segment displays to work, but they are being stubborn and refuse to light up. My problem is probably just a limitation in how much current can be drawn from the microcontroller board.

Speaking of which, the good folks at Farnell let us try out Digilent’s ChipKIT Uno32. Their  website has a ton of excellent electronic products available in the US and beyond.

The above picture is a test to see if my shift register was working as intended, which will be daisy-chained to two more shift registers (and their associated 7-segment displays).

You may notice that the ChipKIT Uno32 (seen in red above) looks strikingly similar to your standard Arduino, well that’s with good reason as it’s built with Arduino compatibility in mind! The Uno32 is powered by a 32-bit MIPS processor, has a large number of I/O ports, 5 external interrupts (versus 2 on an Arduino), is compatible with Arduino shields, and can be programmed using an environment based off the Arduino IDE. My only complaint about the board is that it’s advertised as being fully compatible with Arduino code, and I found that to be only mostly true. When attempting to get the push-buttons to work, I was using the AttachInterrupt() function when using an Arduino, however the AttachInterrupt()  function was not yet supported by their IDE. On the plus side, that was my only gripe with the board, and their team is continually updating their IDE to be fully Arduino compatible.

Additionally (not shown in the pictures), there will be some relays tossed in there so when the timer hits zero, something glorious will happen.

Airhorns, glitter, leprechauns and unicorns. However, due to budget constraints, airhorns are the most likely out of the bunch.

 

Thanks again to Evil Mad Science, as well as Farnell and their US team!

Thursday, September 8th, 2011

Hurray for Happy Steampunk Robot Magnets! They are adorable and fun, loaded with delight for all the steampunk lovin’, magnet-noodlin’, fridge-door hangin’ folks in your kitchen!

PLEASE HELP THEY THREATENED TO GO AFTER MY LAPTOP NEXT

They were thought up and done by the fine folks at Neatorama, who absolutely *promised* they would take the electrodes off my chihuahua and get my power tools back from the scrapyard the very *minute* I told EVERYONE I KNOW about them! Whee!!

There are many cute robots to chose from, they do jolly dances as you make your morning tea! Love them and their nutty boltiness!

Please write to them and say that you just love their steampunk robots, and that you would like to buy them by the gross, otherwise their hands might slip and HAHAHAHAHA OOPS CRISPY @LILFOO! Hahaha! those wacky, wacky Neatorama guys. Wacky.

Oh god please help they have my dog and my mig welder

Gentlemen, we can rebuild him. We have the technology. Part Deux.

Friday, August 26th, 2011

Hello again!

A new installment to the Deus Ex series has been released, and to celebrate the launch Rob Spence was commissioned to report back on the current state of bionic prosthetics.

Rob Spence lost his right eye and replaced it with a video camera, earning the self-proclaimed cyborg the nickname of Eyeborg!

The video contains a good deal of game footage of Deus Ex: Human Revolution in order to compare the cybernetics in the game to their closest real counterparts.

DISCLAIMER: Skip to 0:16 if you want to avoid footage of Rob Spence’s eye being operated on.

Swarms Of Robots Out To Steal Your Books

Monday, August 15th, 2011

Watch out Seal Team Six, there’s a new group of special forces entering the mix – and they’re out for your literature.

Evan Ackerman over at IEEE has written an interesting blog post about the Swarmanoid project.

The swarmanoid robots consist of three types, each specializing in specific tasks: hands, feet, and eyes. When their powers combine they turn into an unstoppable machine on a mission to steal your valuables.

Beethoven Reincarnated in Robot Form

Sunday, August 7th, 2011

I can already hear the squeals of the masses, screaming how cute this thing is.

The video goes through the image processing the robot goes through in order to identify the specific keys on the keyboard – very interesting stuff – then you get to see it (slowly) rock out to Ode to Joy!

The next step, I assume, will be lounge music playing.

Play my song, would you Chiara – just one more time?

Props to Carnegie Melon’s  Tekkotsu Labs  and their open source Chiara Robot.

Vote Us Up To Teach Robots To Kids!

Wednesday, August 3rd, 2011

The Robotics Society of America, proud 501(c)3 nonprofit and co-promoter for RoboGames, has been picked to be in the running for $25k as part of the Pepsi Refresh project!

We Need Your Help! Vote for us to get $25,000 bucks so that we can get underserved kids building robots, and have them compete at RoboGames!

We have until the end of the month to end up in the Top 15 slots!

If we get funded, we’ll have the ability to get a whole slew of robot kits for a whole slew of kids that would otherwise not have them, or the teaching time to learn science math and engineering through robots!

You can sign in to the site with FaceBook, or create an account there; you can text, tweet, reblog it, sing it from the mountain tops, whatever helps us get the word out!

You can vote for us EVERY SINGLE DAY until the end of the month! Vote early, vote often, tell your friends, bribe your enemies!

RoboGames, unlike some other youth robotics programs we might mention, never charges for our Under 18 youth league! We don’t restrict by ability, equipment, or anything else, and we provide valuable experience and international exposure to all our competitors!

We have been doing this for nine years on a largely all-volunteer basis, but just imagine what we, who have done so much for so many with so little, could do if we had some actual cash to grease the skids!

We’ll keep you updated as the month goes on, currently we’re in 48th place!

Thanks very much, we’re all crossing our fingers! Get out there and vote for us! (please. Please.)

Hugging Robot

Tuesday, July 26th, 2011

As the mysteriously, regrettably absent Head Rotor, Back In the Day, once said: “AAAAHGETITOFFMEGETITOFFMEGETITOFFMEAAAAAHHH!”*

It’s the dramatic on-pull of the sensory vest that gets me every time.

Thanks Science Seminars for the link, also for the comment “It is creepy and sounds like a toilet.”

*It should not automatically be construed that The Rotor’s mysterious, regrettable disappearance had anything to do with the aforementioned exclamation. Although if it were construed, automatically or not, it could be neither confirmed or denied. All we know is that he’s gone and WE KNOW NOTHING, OKAY?

Robot Film Fest: Lights! Camera! Servos!

Tuesday, July 26th, 2011

So the Robot Film Fest was a couple of weeks ago in NYC, and because we are a sub par blogger we failed to cover it in any form while we were there (except for a few questionable photos which showed up on Twitter and probably a few embarrassing YouTube videos which have yet to surface).


Pictured: A performance by Tim Laursen and Double Rainbow, the robot rock band. Photo by SB.

Anyhow, the event was a glorious success, and Heather Knight (beloved RoboGames Academic Chair) and the fabulous team from Magic Futurebox who co-produced the event were rock stars and made everyone else feel like one too.

Here’s a few tidbits from the event (for which I was a jury member):

Paparazzi snapped in his face, but 1337 was not fazed. Wearing a scarlet bow tie slightly askew, the 2-foot-tall humanoid robot continued walking down the red carpet – guided firmly by his stooping programmer Carlos Asmat. With the air of a Hollywood film premiere, the first ever Robot Film Festival was underway this past weekend at the 3-Legged Dog Art and Technology Center in lower Manhattan.

-a lovely piece from New Scientist

Cute Photos From Science House

Lots more Robot Film Fest press here.

In addition to failing at blogging the event, I actually achieved the unlikely – I was in the same room as many of my robotic twitter cohort, such as Dustyn Robots, The Chief Robot, and Erico Guizzo – and I failed to meet all of them except for Erico, with whom I had a three second convo before he lolloped off to see his young family.

I blame the exquisite robot-themed cocktails – the BeatBot was an especial favorite.

There are already schemes and plans being put into play for next year, we can’t wait!

The full complement of movies shown at the film fest can be found here, thanks to Marek Michalowski of BeatBots

Mighty Morphing Zenta Robots!

Monday, July 25th, 2011

I came across Zenta’s Robotic Creations blog while looking up information on my own biped, and my jealousy meter is off the charts.

Just watch this video – Words, I have none.

Working with similar robots, I can only hope that one day I can make them move that smooth and agile.

Zenta’s latest project is a morphing robot. That’s right, a MORPHING ROBOT.

I tossed this brilliant Norwegian a few questions, and he was nice enough to get back to me!

 

What’s your background and how did you get into robotics?

My background is engineering. I’ve always been fascinated by all kind of robots since I was about 6 or 7 years. (I’m now 38 year) .I began building robots very early, using mostly meccano. At some point I found meccano a bit limiting and started making custom parts. But I didn’t get more serious into hobby robots before 2006 when I started on my rather famous Phoenix hexapod.

You mention in your blog that Archer is your first biped, why did you decide to construct a biped rather than continue your work with hexapod (and similar) projects? What are the different problems you run into when designing a biped versus designing a robot with more than two legs?
The main reason for why I wanted to construct a biped is that I had some ideas of how to control it using Inverse Kinematics (IK) based on the current code used for controlling hexapods. The main difference is balancing/stability. Also gear-slope/backlash in the gear of the servos is a challenge on bipeds. Keeping the weight as low as possible is also more important on bipeds. When it comes to stability I tried solving that on Archer by simply moving electronics and battery from side to side.

Your new hexapod, MorpHex, looks absolutely amazing. How did you come up with its unique design, and what difficulties you encountered and how they were overcome?
Thanks, glad you liked it! I got the idea for building MorpHex for over a year ago. Mainy I got the idea watching my two eldest kids playing with Bakugan and I thought it would be cool to make a hexapod that could transform into a sphere and back to a hex again. I’m still working on MorpHex, you can see what I’ve accomplished so far on my blog. The main challenge with MorpHex was to make the variable sized body, the body needed to expand for making more space between the leg sections. There has been several difficulties during the making of MorpHex. At some point I considered to end the project, so I had to do some changes to the leg design for making the robot less heavy and also for removing some conflict between the sphere sections.

A lot of your robots seem incredibly lifelike and fluid in their movement, how did you manage to accomplish this?
The smooth movement are simply accomplished by accurate control, correct math and correct timing. Jeroen Janssen’s work on the Phoenix hexapod Basic Atom Pro code make this rather easy to accomplish. Instead of using a PS2 controller, I’m using a custom made remote controller. The remote controller play a big role for accurate control.

Of all your previous projects, which one did you enjoy working on the most?
Oh, thats very hard to say. I enjoyed them all. I think I’ve to say Phoenix was the project I enjoyed most.

What future projects are you looking forward to working on?
A full humanoid biped, a new hexapod and or a new quad…

Lastly, if someone is interested in robotics, but has relatively little hands-on experience, where would you recommend they start?

Lego mindstorm or VEX Robotic System is a very good plattfom. I’ve to say I’ve not worked with either of them. But I plan to introduce Lego Mindstorm for my kids one day. Also, a hex or biped Brat kit from Lynxmotion is a good start.

The Newest Of ROBOT Magazines!

Thursday, July 21st, 2011

The latest issues of Robot is out! Eveyrone go snag a copy at one of your fine local publications depots.

Robot Magazine July 2011

We make special note of this, because while Robot is indeed a fine, fine publication, Our Man In Japan Lem Fugitt has a really nice cover article about a neat sounding little event called RoboGames which apparently happened in the Silicon Valley this past April.

We love Lem, because not only does he have an exhaustively informative fire hose of robot information over on his blog (which blog we here would very much like to be when we grow up), but he also is a dandy fine person and we always look forward to plying him with alcohol and questionable conduct when he is here on his annual US spring sojourn.

Plus he’s got awesome footage of me giving Team RioBots what for after an incident in the arena (Naughty Brazilians!).

We also welcome with open arms the possibility that more of our friends from Robot Japan and the greater Tokyo Area will come show the US competitors how it’s done for RoboGames 2012!

So go out and get a Robot right now and support printed matter.

Error – Stack Overflow of LOVE

Thursday, June 30th, 2011

Love robots? Now they can love you back!

Welcome to Hooman Samani’s Lovotics – an area of research dealing with human-to-robot relations.

Across 11 research papers, Samani has outlined — and begun to develop — an extremely complex artificial intelligence that simulates psychological and biological systems behind human love. To do this, Samani’s robots are equipped with artificial versions of the human “love” hormones — Oxytocin, Dopamine, Seratonin, and Endorphin — that can increase or decrease, depending on their state of love. On a psychological level, by using MRI scans of human brains to mirror the psychology of love, the robots are also equipped with an artificial intelligence that tracks their “affective state”; their level of affection for their human lover.

Observe as this lovely combination of R2D2 and Roomba strives for your affection:

 

After reading this article I immediately visited this tv-tropes piece, knowing all-well that I could suffer a similar fate as this fellow.

I came to the conclusion that one of my favorite responses to “What is this thing you call love?” was from a jolly assassin droid by the name of HK-47:

Definition: ‘Love’ is making a shot to the knees of a target 120 kilometers away using an Aratech sniper rifle with a tri-light scope. Statement: This definition, I am told, is subject to interpretation. Obviously, love is a matter of odds. Not many meatbags could make such a shot, and fewer would derive love from it. Yet for me, love is knowing your target, putting them in your targeting reticle, and together, achieving a singular purpose, against statistically long odds.

 

Now please, stop asking us about pleasure bots.

I blame the Svedka robot.
