Auto-tracking sentry gun build

The beginnings of an Aliens-style (except, you know, without all the actual bullets and killing and so forth) automatic sentry gun from diederick. The tracking platform is obviously flexible, but I think he intends to mount an AirSoft gun. Build details and code downloads are available from his website.

Automatic sound-responsive puppet mouth

Guilherme Martins built this "talkie walkie" in response to a challenge to build a robot using only one servo. It responds to sound in real time, automatically controlling the movements of a lip-syncing paper mouth. [via Hack a Day]

iPhone Rock Band robot

The rhythm game arms race continues -- if they miniaturize the guitar games, we will miniaturize the guitar game robots!

My friend Joe Bowers writes:

Rock Band has been released on the iPhone, and even though its a lot of fun, I would rather have something play it for me. Preferably a robot! The light sensor sends data to an Arduino, which is waiting for a spike in the data. The Arduino runs the sensor data through some averaging filters, and sets a threshold for on and off. The iPhone touch screen isn't like most PDAs. It uses a capacitive touch screen. I had some conductive foam laying around, its usually used for shipping sensitive electronics. If I used something non conductive, like a plastic pen, the foam would do nothing to the screen. My solution to this was to put thin copper wires into the foam (I also used these wires to attach the foam to the servos)... Add all of the above together into a modified Pelican case, with a lot of hot glue (non glittery) and you have a robot that will gladly beat all your difficult songs, sit back and sip some fine tea.

Cockroach robot falls 28m, keeps running

The UC Berkeley Biomimetics Lab has created DASH (Dynamic Autonomous Sprawled Hexapod), a cockroach-inspired robot made from laser-cut cardboard laminated with some polymer. It runs fast and can withstand falls of 28 meters, after which it just keeps on about its business.

From MAKE magazine:

In MAKE, Volume 19: Robots, Rovers, and Drones, learn how to make a model plane with an autopilot and a built-in robot brain. We'll also show you how to make a comfortable chair and footstool out of a single sheet of plywood, a bicyclist's vest that shows how fast you're going, and projects that introduce you to servomotors. All this, and lots more, in MAKE, Volume 19! Subscribe here, or buy the issue in the Maker Shed.

Muralizer prints art on the wall

Josh writes in to spread the word about the Muralizer verticle surface printer/plotter project - which is hopefully a kit in the making -

t's a drawbot that takes SVGs as input, letting you print vector graphics really big. The project was started at noisebridge, San Francisco's hackerspace, earlier this year, and we got a prototype going (a bit of video is up on the page).
I'd love to bring this piece of open hardware to the community as a kit, but need some help to do so. Inspired by the success of MakerBeam, I set up a kickstarter page. It would be great if people could pledge even a little bit to help make this tool available to artists (and those of us who want to be artists but are better at soldering than painting).

This could foreseeably give artist's assistants a run for their money (do they even get pay?) More on the project's planning and development can be found on Kickstarter & the Muralizer blog.

Where are they now: Pleo the Dinosaur

He's baaaaacck! Pleo, the long-hyped, short-lived robotic baby dino is back on the market. Robert Oschler, of RobotsRule, has posted a piece, The Inside Story Behind Pleo's Rise, Fall, and Resurrection, that includes an interview with Derek Dotson, one of the founders of Ugobe, and now the CEO of Innvo Labs, the company that acquired the rights to Pleo.

RO: Are there plans for any new accessories or new Pleo models?

DD: I can talk about the 2010 Pleo model. That model will look the same as Pleo does now except it will have a new paint job and eye color to differentiate it from the current Pleos. Over the coming year we intend to give Pleo more depth to his personality and utilize the sensors better. For example, Pleo doesn't do a whole lot with the camera in his nose right now. It's not the hardware since the camera is a good quality camera. However there's a lot of room for improvement in the software. An example of a specific feature people want badly is getting Pleo to come to you. The 2010 model will do that. Also, Pleo uses power more efficiently which will lead to longer play times. To make Pleo more realistic, Pleo will develop certain character biases at birth so that everyone's Pleo will be different. As for the sensors, the reason why they are currently underutilized is due to a bottleneck in the serial bus that connects them to Pleo's processor resources. That's something we can fix without drastically altering Pleo's architecture. Once that happens, we can do more with them when it comes to Pleo's hearing, vision, etc. Beyond 2010 there will certainly be new creatures other than baby robot dinosaurs.

Introducing the Creeper 2 - CANDY

WGhost9 writes -

Designed, built, and programmed in about record three weeks! It runs C on an Axon microcontroller. It uses all digital servos and can lift over twice its body weight. The software (soon to be given out open source) allows for six synchronous degrees of motion. Future additions will include foot sensors and a remote control option.

Mr. Wake, the uncatchable alarm clock robot

Here's another awesome project by Vadim Ryazanov of Let's Make Robots. Called Mr. Wake, this robot has the duty of protecting its alarm clock from any bleary-eyed, would-be assailants. Instead of running away after its snooze button has been pressed, like the Clocky, this 'bot engages a homebrew IR sensor as soon as the alarm goes off, and takes off if it detects anything even trying to get near the button.

I love the choice of building materials, especially the frame made of heat-formed plastic pens. Nice work!

PETMAN Prototype

The video you'll be seeing on every tech site shortly :)

Biped robot the balances dynamically using a human-like walking motion. It is a close relative to BigDog, sharing elements of the mechanical design and control.

How-To: Homemade pen plotter with laser attachment

Very thorough build notes from Viacheslav Slavinsky, who built a plotter from scratch, then souped it up by adding a 300 mW laser in place of the pen. I was interested to note that while 300 mW isn't a lot of laser power, apparently it can cut through slightly more than a centimeter of "high density foam." I'd be curious how it fares against EPS and/or XPS. [via Hack a Day]

Make robot parts with papier-mâché

What do you do if you don't have a vacuum former, and need to make a part for your robot body? Well, Vadim Ryazanov over at lets make robots has a simple solution: make them with papier-mâché! By using paper and a 1:1 mixture of wood glue and water, he was able to make a hemispherical shell for an upcoming project. Great idea!

How-To: Compressed air system for haunt props

Good tutorial on putting together a pneumatic power system for "home imagineering," as as the folks at Phantasmechanics call it. We've blogged their stuff a couple times before.

Incredibly creepy photoreactive animatronic, um, thing

From Let's Make Robots user lefthandsh8k, this truly disturbing light/shadow responsive haunt prop. It's controlled by a PIC16F84A and has seven servos and several vacuum-formed pops. The rest is "plywood, paper clips, and popsicle sticks." [Thanks, Matt!]

Animatronic zombie

Its creator calls this a "groundbreaker" zombie, and since he obviously knows way more about Halloween gadgetry than I do, I should probably bow to his usage. But I have to say I feel like "groundbreaker" should be reserved for props that actually, you know, appear to break out of the ground.

Semantics aside, this animatronic zombie is so well done I was tempted, for a moment, to believe it was a fake--like, a person in a costume half-buried in a hole. Found it in this thread at Haunt Forum. Well done, Dr. Morbius!

Lego model of industrial pallet handler

OK, Jay, this clip takes a bit of set-up. Basically, it's a model of a factory-floor machine for moving pallets around a square assembly line. You put a pushing arm at each corner of the square and trigger them alternately in caddy-corner pairs. Some bright bulb figured out, however, that if you join two square tracks at one corner, you can do twice the work with only two more arms. Watch the intersection for a minute to confirm that the contents of the two square tracks are not mixed, which to me is counterintuitive. Here's a video of the simple, single-square case that apparently started the trend. [via The Automata / Automaton Blog]

Intern's Corner: How I designed Makey the robot

MAKE: Intern's Corner
Every other week, MAKE's awesome interns tell about the projects they're building in the Make: Labs, the trouble they've gotten into, and what they'll make next.

By Kris Magri, engineering intern

Part I: The First Design

This summer I was given a once-in-a-lifetime opportunity to make a robot for the pages of MAKE Magazine (Volume 19, "My Robot, Makey"). As an intern, I had the inside scoop that an upcoming issue would focus on robotics. I talked with one of the editors, Goli Mohammadi, about including a step-by-step article showing people how to make their own autonomous robot from scratch, using an Arduino microcontroller. She took the idea to the rest of the crew, and they gave me a chance, asking for a draft article about the robot. I went into hyper-drive that weekend, designing and building a robot prototype in 44 hours over three days. This is a behind-the-scenes look at designing Makey.

The first thing I did was sketch ideas on paper. I based Makey on WALL-E, the little yellow robot hero from the movies. I quickly noticed that WALL-E's eyes are huge in contrast to his body. I knew the dimensions of the Parallax Ping sensor, which I planned to use for Makey's 'eyes,' so I realized I'd need to keep Makey's body as small as possible, to make the eyes look as big as possible.

I used Autodesk Inventor to design Makey. I can't say enough good things about this software. I've been using PCs for a good long while, and compared to big Unix workstations, I've never been impressed with what PCs can do for you. Inventor changed that. Inventor is the single best reason to own a PC, IMHO. I learned Inventor at school as part of my engineering curriculum, and this software is the "missing link" that has finally allowed me to design robots like I want to. Makey is the fifth robot I've built from scratch, and the first one I've designed on the computer, and the difference is like night and day.

Señores y señoras...El Sr. Bones y los Gourditos!

It looks like Mr. Bones does not actually have a singing part in this delightful orchestration of Danny Elfman's "This is Halloween" from The Nightmare Before Christmas by YouTuber HalloweenJared. He just bobs his head and taps his foot. (Maybe he needs a tambourine?) The anorexic front man for the Gourditos does, however, show off his famous vocal chops in their cover of Bobby Pickett's "Monster Mash," and also here in a smoking duet version of the elder Ross Bagdasarian's "Witch Doctor." There's some how-to info on HalloweenJared's blog here. I wonder if they do funerals?

Skiing robot caught in steady decline

Researchers at the Jozef Stefan Institute built this fun skiing robot. It consists of two computing systems, one that acts as a vision and route planning system, and the other for stabilization and steering. Besides using it to make funny videos, they also plan to use it to test ski equipment and to build virtual reality models of the winter sport. I just hope it can move fast enough to avoid the abominable snow monster!

There doesn't seem to be a web site to document the robot, however the folks at IEEE Spectrum have a nice writeup of the conference talk it was presented at, and the paper is here (behind a paywall). [via neatorama]
