InventGeek’s Paintball Turret = Awesome

Monday, March 2nd, 2009

Funny I found this, because I was just thinking that if (when) the Zombie Armageddon hits, I’d need to fortify my Costco fortress (find your own) with some automatic turrets capable of firing zombie repellent, and what better project to detail building exactly that?

InventGeek.com has painstakingly detailed all of their most excellent work that went into building this beauty, and while we have seen a paintball turret pop up over the years, none have even come close to such an elegant execution. Complete parts lists and even the ability to purchase the acrylic parts are available, so you too can build your very own “Zombie Repellent Paintball Turret” to fortify your “Post-Zombie Armageddon Costco Fortress” (dibs on the one by my office!).

Give your Bioloid a new paint job!

Thursday, January 29th, 2009

Okay, technically it isn’t ‘paint’. Dye would be more appropriate.

I decided that my plain old white Bioloid was boring, so I started looking around for the best way to change his color scheme. The Bioloid brackets are pretty sturdy, and thus resistant to paint and markers. I found mixed results searching through on various experimenters success in dying their brackets, but I figured I would give it a shot.  After playing around with individual brackets I figured out the correct dye-water mixture, length of time, and heat, and it turned out even better than expected!

Here is a step by step tutorial detailing what it takes to get your Bioloid dyed a different color. I used black, but since the brackets are white I would assume that just about any color would work.

Note: Dye your brackets at your own risk! While I’m quite detailed in my instructions, I nor Trossen Robotics hold any responsibility if your brackets end up pink, or otherwise destroyed.

Easy Telepresence Solution!

Tuesday, December 2nd, 2008

We’re always on the lookout for useful and inexpensive gadgets to add to our Robotics Lab, and while searching around for a small, inexpensive Wifi (as in 802.11) camera for use in Mech Warfare I finally settled on the Airlink 101 SkyIPCam250w Part #AIC250W. Personally I found mine at a local Fry’s Electronics for about $105, but we also sourced them online here.

Here is my quick review here on the forums of this camera:

Image quality is mediocre, but good enough to view things at a max of 8-10 feet. Frame rate is 30+ and response time is in the 50ms range running the camera at 320×240.

Main board is 10cm x 5.5cm. Camera board is 5.5cm x 3cm and attaches to the main board at a right angle. It appears to be a 1mm spaced header pin port, so it could easily be extended for custom mounting solutions. Entire camera unit stripped down and including antenna weighs 91 grams. The antenna is a u.FL connection, so this could be replaced with a custom solution if needed.

Overall a solid little camera for the price. If you’re on a budget, this is about as good as it gets. Keep in mind for ‘competition’ performance, you’ll need to run it at 320×240, but that can be stretched. Image quality is enough to pilot and aim I would say, but I wouldn’t expect to read text with it. Definitely usable for Mech Warfare within 10-15 feet though. Oh and the IP web interface uses Java and/or Active X, so you could pull the control from it and add it into a custom form easily.

Here are some pictures! (click to enlarge)

Since we don’t care about the bulky exterior casing, here’s what it looks like stripped down:

And this is with the camera board removed:

Zombie Robots!

Wednesday, October 15th, 2008

You heard it here first! Rodger Cleye from our forums just posted his newest invention, Donna the Dead Bot. He built this using a motorized wheelchair base rigged with an R/C system, and adding some PVC pipe, a strobe light, and a glowing eye skull and some ghost-like apparel. Not only is this an awesome invention for scaring the candy out of kids trick-or-treating, it’s a solid example of ZombieTech™, which is the fusing of zombies and robots… which just so happens to be our only chance of survival if the Skynet and Zombie armageddons happen to occur simultaneously. Scaring kids and saving future lives, go Rodger!

More DIY Wall-E Madness!

Monday, October 13th, 2008

You can tell that Wall-E was a major hit with the roboticist community by the number of Wall-E hacks and DIY bots we’ve seen over the past few months. First of all, forum member 4mem8 posted his Homebrew Wall-E robot and won the last round of our competition. Then Bazmarc wow’d us with his Lego NXT Wall-E which put my self proclaimed Lego-Genius skills to shame. Keeping with the trend, DJSures has impressed us with his DIY Hacked Toy Wall-E.

He bought one of the cheap little toy Wall-E’s you find in toy stores now, but obviously was not impressed by its capabilities. He set out to make it his own, replacing the single motor with a handful of servos, hacking the voice chip, adding a custom PIC and sonar for autonomous navigation, and overall doing a fantastic job bringing this robot to life.

Here’s a video of the little guy in action. Make sure to check out his thread for some great photos of all of his work.

Micro Spy Car says: “I spy because I love”

Thursday, August 28th, 2008

We have some pretty cool toys laying around in the bowels of the Trossen Robotics R&D department. Late last night I had a stroke of genius and combined two readily available electronic gadgets to make a VERY cool little toy, the Micro Spy Car. Afraid of Big Brother watching you? Well now you’ll have to look out for Little Brother too.

While digging around for a spare Anti-mass Spectrometer I came across an awesome little wireless camera, the Swann Black Hawk Wireless Color Camera with Built-in Battery and 2.4ghz Receiver (which has a product line about ‘keeping an eye on loved ones’. Sure.):

The camera itself is TINY, measuring a little over 2″ long and with a built in lithium battery. Like any self respecting geek, thoughts of mounting this to a small R/C car and driving it into the girls locker room immediately filled my head. Except, I’m not in highschool anymore and I certainly don’t want to see my hairy ass coworker naked. Oh well, spying on clothed people around the office will have to suffice.

We just so happened to have a TINY Team Losi Micro-T R/C car sitting around the office:

Check out our Tutorials Section to see a step by step on just how easy it is to make one.
For size comparison, here’s the Micro Spy Car with an Ultra-Exclusive Limited Collectors Edition Official Trossen Robotics Coffee Mug:

Now for the fun part- driving around the office with it! I plugged the video receiver into a little portable LCD display we had laying around and went nuts.

You can also plug the video receiver into a USB video capture device to view and record your shenanigans on your computer. Here’s a quick video we shot of the Micro Spy Car driving around our back room:

Laser Harp Mk. III: Now With More Wiimote

Friday, April 25th, 2008

Stephen Hobley is at it again.  His laser harp was cool enough to win second place in our project contest a few months back, and since then he’s managed to make it even cooler.  Using a Wiimote to accurately track the positions at which the beams are interrupted, he added some very clean and precise pitch control to the already impressive instrument.  Watch the video.  After about a minute of demonstration, he gives a quick explanation of how the modification works, so be sure to watch the whole video.

He started a thread about this in our forums, so head on over there to give him props, ask questions, etc:
Laser Harp Mk III

February TRC Project Contest Winners!

Tuesday, March 4th, 2008

In case you’re new to the Trossen Robotics Community, here’s a quick refresher on how this contest works:  First, all kinds of fantastically talented and dedicated people come to our Project Showcase forum to tell us all about the projects they’ve been working on.  Periodically, we (the Trossen Robotics team) sort through these projects, and score them very scientifically in the following categories: "Wow" factor, Ingenuity, creativity, and presentation (this includes graphics, videos, documentation, explanation, etc.).  This is the fourth contest we’ve run here at Trossen Robotics, and the projects just keep getting cooler!  This time around, we extended the deadline and upped the stakes.  Since the last contest, the community has grown and expanded well beyond our expectations, and this has resulted in some of the best work we’ve seen yet.  If you showed off your project in our Project Showcase forum, give yourself a big ol’ pat on the back.  Now, let’s get to the meat and potatoes.  Here are the runners-up and winners, in suspense-building ascending order!

- – - – - – - – - – - – - – - – - – - – - – -

Honorable Mention

Project: "Johnny 5.3"

Creator: Andrew Alter (Tyberius)

We’ve been working a little too closely with Andrew to let him enter the contest, but we can’t totally leave him hanging.  He’s been building a "Johnny 5"-inspired humanoid/trackbot hybrid, and it’s really coming together.  His brain (Johnny’s, not Andrew’s) is a Pico-ITX running Windows XP Pro.  It has a vocal synthesizer, great big grippers, a reinforced suspension system, a snarky personality, and I’ve heard that it drives around harassing Andrew’s baby.  It’s the embodiment of robotic awesomeness, in other words.  Check out his thread, picture gallery, and his blog.

Runners-Up

Project: "Leviskate"

Creator: Rodger Cleye
Average Score: 7.63 / 10
Prize: $20 Trossen Robotics Gift Certificate!

The Leviskate is a "self-balancing motorboard."  Kind of like a Segway for people who really like head injuries.  Seriously though, this contraption is truly awesome.  There are some cool videos in Rodger’s thread, too.  Our favorite thing about the videos is that Rodger sounds genuinely amazed that it actually works.

Project: "The Bratinator Project"

Creator: SN96
Average Score: 7.67 / 10
Prize: $20 Trossen Robotics Gift Certificate!

It walks, it talks, it scares the kids.  It’s… the Bratinator.  Built around the Lynxmotion Brat biped, this monstrosity features speech, binaural hearing, a custom-machined aluminum head.

Project: "Gepetto"

Creator: darkback2
Average Score: 8.25 / 10
Prize: $20 Trossen Robotics Gift Certificate!

It really pains us to see Gepetto in the runners up, instead of placing in a cash-winning position, but sometimes that’s just the way it goes.  This was a very close race.  This bot is beautifully made from wood and metal, has a really cool suspension system, carries its laptop brain around with it, and is programmed with some really interesting behavior/mood software.  That’s really just the tip of the iceberg, so you’ll have to read through the thread to see Gepetto’s full story.

Third Place

Project: "eyeRobot"
Creator: Nathaniel Barshay
Average Score: 8.38 / 10
Prize: $100 Trossen Robotics Gift Certificate!

The eyeRobot is a robotic guide for people with vision impairments.  It has a whole slew of IR and ultrasonic range sensors for collision avoidance, and pathfinding software to keep it moving through the clearest area.  This was a proof-of-concept prototype meant to "marry the simplicity of the traditional white cane with the instincts of a seeing-eye dog."  This project is going places, and hopefully one day it will help other people go places.

 

Second Place

Project: "Frameless Laser Harp"
Creator: Stephen Hobley
Average Score: 8.88 / 10
Prize: $250 Trossen Robotics Gift Certificate!

Twenty-two years ago, he saw Jean-Michel Jarre play a laser harp at a concert, and from that day he’s been on a mission.  This mission finally came to fruition last month, when he completed his own laser harp, and let me tell you, it’s a pretty stunning piece of equipment.  Using a galvanometer to very rapidly and precisely aim a pulsing laser, light sensors to detect where a beam has been interrupted, and an Arduino brain; the harp sends MIDI control signals to a synthesizer.

 

First Place

Project: "Phoenix"
Creator: KÃ¥re Halvorsen
Average Score: 9.63 / 10
Prize: $500 Trossen Robotics Gift Certificate!

Phoenix is a six legged walking robot.  Wait, we know some of you out there may be thinking that hexapod robots are old hat.  Well, you’re wrong.  So very wrong.  Wait until you see it move.  Phoenix’s real beauty lies in her graceful motion, which is some of the most convincing and eerily lifelike that we’ve seen in a robot that uses standard hobby servos and a common off-the-shelf servo controller.  The kinematics are computed by an intricately programmed spreadsheet, which we highly recommend you check out if you’re a fan of trigonometry.

We want to thank everyone for their great submissions.  If all goes as planned, the next contest (which is already underway) will conclude at the end of May 2008.  You can stay up to date on contest rules and regulations at the Trossen Robotics Project Contest page, and start posting your projects in our Project Showcase Forum.

CES 2008: Jeffrey Stephenson custom case mods

Wednesday, January 9th, 2008

Jeffery Stephenson of Humidor PC fame was also at the press lunch with his latest creations the Pico Bayard and the G-metric Nano. Jeffrey specializes in making really beautiful custom PC cases using small ITX boards that combine modern technology with classy old world style. His creations are vaguely steampunk without the steam. Jeffrey has a whole pile of his projects profiled on his website SlipperySkip.com.

Jeffrey describes his Pico Bayard: “This computer was inspired by a design by the French clockmaker Bayard. It is an example of the art deco skyscraper school of design that flourished between the world wars. The clock’s landscape orientation was rare for the period.

Surveyor SRV-UAV?

Tuesday, December 4th, 2007

Ok, this is just too damn cool. The Surveyor crew have integrated the SRV-1 controller with a quad-rotor helicopter.

The heli, called "X-3D-BL Scientific," is from a German company called Ascending Technologies GmbH.  I knew it was easy to use the SRV-1 controller for other wheeled vehicles, but seeing it on a UAV is pretty exciting.  They don’t have too much info up yet, but it sounds promising.  Here’s a video of the aircraft (without SRV-1 controller) in action:
