Saturday afternoon robot cooking

What happens when you combine an IR tracking PS3 Eyetoy, and a high-resolution projector? If you answered multi-touch display, you’re on the right track. Add a Wii Nunchuck controlled robot, a pinch of Community Core Vision tracking software combined with Processing, and the piece de resistance, a modified Memo TUIO particle system and you get the mesmerizing video above.

Check out this combination of crazy robotics and more with SparkFun’s free robot hobby builders meet-up on Saturday.

Virtual Theremin

[Mojo] has taken a lot of the complex circuitry out of the mix by creating a virtual Theremin. A Theremin is an electronic instrument, usually with two antennas, that senses the proximity of the player’s hands to the instrument and responds accordingly.

This design, called the AirDeck, uses a Wii remote as an IR sensor and two gloves with IR LEDs in them. Data from the Wii remote is processed by a custom Java app that converts it into sound. [Mojo's] interface also includes some alternative options such as a turn-table scratch interface.

In the end this is still just a synthesizer/midi controller and cannot stand up to the real thing. However if you’re not an accomplished player you’ll probably never notice the difference.

(Remote controlled robot) car vs (solar charged) tank

[Matthias] sent in his team’s iPhone Robot (CAR) project in response to yesterday’s iPhone controlled solar charged tank. Unlike the tank, the iPhone car is controlled via Bluetooth BTnode and BTstack, and also isn’t solar-powered. However, both projects utilize iPhones and readily available components. We particularly liked how it not only used a multi-touch input, but also the accelerometer within the iPhone. It seems some competition is stirring, lets see who wins out.
