This year at the creepy robot dace-a-thon, also known as the Robo-one dance competition, we get to see the creepy brought to new levels. We thought the Lou Vega decapitated head bot was creepy, but somehow these people managed to make a biped out creep a hexapod. Watch above as this uncanny valley resident tries to shimmy into your heart. We really are impressed by these bots though. The world of robot dancing has come a long way, those little servo bags are doing a better job than us on the dance floor.

Automatic Pneumatic Drum Kit

November 23, 2009 by Jake W 16 Comments

Move over Steve and PEART… there’s yet another robotic drummer in town. [Fauzii] tipped us off to his own MIDI-controlled creation – WizardFingers. According to him, WizardFingers is already capable of 64th note rolls at over 250 beats per minute. That’s on every drum simultaneously. Each drum is hit with a lever attached to a linear pneumatic actuator. A laptop running MAX/MSP generates MIDI sequences, which are sent to Doepfer MTC64 board. All of these actuators are hooked up to the board, which sets them off in sequence.

[Fauzii] ultimately hopes to develop AI software that will allow WizardFingers to compose its own tunes on not only a drum kit, but bar chimes and an organ as well. His site documents the whole concept quite well (just watch out for wild cats).

Outerspace: Reactive Robotics

November 18, 2009 by Caleb Kraft 17 Comments

While Outerspace may not have an extremely useful function, being an art installation, we really enjoyed reading through the build information. Basically, Outerspace is supposed to appear to be curious, exploring it’s surroundings and reacting to your contact. We do enjoy a little bit of personality in robots, so this seems like it could be fun. The head has 5 photo sensors and each piece of the “arm” has capacitive sensors. This allows Outerspace to sense what is going on. The motion itself is controlled by 4 servos in the base pulling cables that run through the body.

The programming seems like it could use a little work to achieve the effect of being “curious”, but we see potential here. You can see a video of it in action here.

BEAM Robot Tumbles Aimlessly

November 17, 2009 by Mike Szczys 14 Comments

[Harm’s] tumbling robot from a few years back is an excellent study in simple motion. Foregoing wheels or legs, he uses four flippers to roll the robot around the room. Two motors are used, each in charge of two flippers. Identical but separate circuits drive the motors with a 74HC240 gate IC monitoring the continuously rotation. When a flipper becomes stuck, the circuit reverses the rotation of the motor so the simple bot can tumble its way out of a jam.

The circuitry is less advanced than some of the BEAM builds we’ve seen before. That doesn’t diminish the cleverness of his design and we think BEAM robotics are great way to get your head out of the computer code and go hardware only. After the break you can take in some video of the tumbling motion. We’ve also included a video of another bot from his website that uses concentric rings for another type of unique locomotion.

Robot Interface Lets Fingers Do The Walking

We’re filing this one under “best interface implementation”. This robot is controlled by finger gestures on the surface of an iPod Touch. It can walk forward, turn, sidestep, jump, and kick a ball based on the input it receives from your sweaty digits. Unlike vehicles controlled by an iPhone (or by Power Wheels), this has some potential. Especially considering the inevitable proliferation of multi-touch devices in our everyday lives.

AWE: A Robotic Wall

AWE is an interesting project, where your office wall is a helpful robot. That’s the goal anyway. The wall is articulated and can reconfigure its shape to fit your needs. You can see in their video that they have come up with several specific uses for AWE at different positions. We want to like AWE, we see that there is potential there. The video hasn’t won us over, there just wasn’t enough added benefit over a simple setup like a projector mount. We think the real benefit just isn’t as obvious. When we saw the girl stand up, and the wall back away intuitively, our attention was regained. What potential uses do you guys see?

Another Mini KeepOn?

October 31, 2009 by Caleb Kraft 21 Comments

[flickr video = 4060182274]

[Eustice Scrubb] has posted some videos and pictures of a robotic “eye stalk” that he’s building. It looks like the final version is using 3 servos in an arrangement like tendons through a slinky jr. The ping-pong ball on the top has a BlinkM inside it. You can see a video after the break that shows the three servo tendons in motion. The whole thing is controlled by an Arduino and one of his pictures states that it plays mp3s and has an internal pendulum. None of his pictures seem to implicitly state what it is meant to do though.
