Flatpack Walker

If you’re into robotics, you’re probably already familiar with the 2 motor walker. This design, usually used in B.E.A.M. robotics is a pretty easy way to make a 4 legged walking robot. [Edwindertien] has made the design a little bit easier to build with these flatpack walker plans. He used 4mm thick birch, cut by laser to get his walker into shape, but the design would work with almost any material. His walker is Arduino powered, so it could be programmed for all kinds of behavior, especially if you add some sensors. You can see his bot in action after the break.

Voice Controlled Home Automation

[Brian] sent in this writeup on his voice controlled home automation system. Starting with the Microsoft SAPI, a voice recognition system, he programmed some basic home automation. In a move that makes this project decidedly more awesome, he decided to build a physical representation of his automation system. This disembodied head is “Stephanie”. She responds to her name, has an articulated jaw that moves with the syllables in the words, and even ejects her “brain tray” on command. We want one.

There is lots of information on his site about the circuitry involved, as well as source code and a video. You can see the video after the break.

MCU Controllable Camera Mount

head

[psymansays] needed a panning head for his robotics projects. Already being familiar with the NXP LPC2148 from work, so he wanted to use that to control it. he built his own carousel out of old CDs. The axle of the carousel is a potentiometer. This is what he’s using to determine position. The gear motor was actually cobbled together with bits from a windup toy and an old motor. This may be a bit bulky, but it seems not only functional, but fairly versatile.

The Ponginator

All bow your heads in reverence to the Ponginator. This bad boy is a performance robot, mounted to the end of a 3 story tall crane. He makes all kinds of noises, flashes all kinds of lights, and shoots ping pong balls at 170 miles an hour. This thing looks like it would be so much fun to play with. listen to it as he’s talking and you’ll pick out all kinds of Sci Fi sound effects, from Portal sounds to Star Trek sounds. Check out the second video on the site to actually see the Ponginator shooting.

Robotic Baby Crib

This surprisingly pleasant looking crib is actually a robot, designed to keep babies quiet and happy all night long. Once inside and locked up, the baby is under the robot’s care. When the robot senses crying, it rocks gently back and forth. This should allow parents the time to catch some sleep. As pointed out in the article, the $5000 price tag is a bit steep. Especially considering the fact that you can get a much less technologically advanced equivalent for relatively cheap. How many of you hackers have babies? What hacks did you do to get your babies to sleep?

Radio Controlled Beetle

February 9, 2009 by Caleb Kraft 57 Comments

Scientists at the university of California have managed to implant a chip in a giant flower beetle that makes it respond to commands from the computer. They can tell it to fly, stop, turn left and turn right. The controls are done through its optic nerves and wing muscles. Though the article states that flight signals are sent to the optic lobes and steering is done through stimulation of the wing muscles, the video shows steering being accomplished through optic lobe stimulation.

Though we’re sure there’s some grand scientific goal behind this, we can’t help but think (hope) that we’ll be seeing giant robot controlled beetle battles with lasers and rockets.

OpenVulture, Software For Unmanned Vehicles

The first talk of ShmooCon was [Ethan O’Toole] and [Matt Davis] presenting their OpenVulture software for unmanned vehicles. In the initial stages, they had just planned on building software for Unmanned Aerial Vehicles, but realized that with the proper planning it could be used with any vehicle: airplanes, cars, boats, and subs (or more specifically, their Barbie PowerWheels). The software is in two parts. First is a library that lets you communicate with each of the vehicle’s modules. The second half is the actual navigation software.

They’ve spent a lot of time sourcing hardware modules. They are looking for items that work well, aren’t too expensive, and have a fairly plug and play implementation. For their main processor, they wanted something that wasn’t a microcontroller and could run a full Linux system. The ARM based NSLU2 NAS seems to be the current frontrunner. You can find the opensource software and descriptions of the supported modules on their site.

They’re building the first test UAVs now. One has a 12 foot wingspan for greater lift and stability. We’ve covered the Arduino based Ardupilot and other UAVs in the past.
