The university of Delft in the Netherlands has added a newer, and even smaller addition to their Delfly family of robots.

The DelFly Micro only weighs 3 grams and has a size of 10 cm from wing tip to wing tip. This makes it the smallest flying ornithopter carrying a camera in the world!

There is a podcast with more details up on the Robots podcast site

This amazingly light robot carries a camera, and can fly for up to three minutes under it's own power. It seems like only yesterday that Dragonfly spy robots were the fodder of conspiracy theorists, and now they are a reality.

Experienced circuit bender David Cranmer has created this noisy but compelling hurdy gurdy out of a batch of four skinned Furbies. The interface is particularly interesting, since it gives a completely human and analog tempo control to the beasts.

Be forewarned that the creatures don't seem to enjoy their new lives very much, and I wonder what they did to deserve such torment. At the time of this writing, the device was up for sale on Ebay, so you could just ask the poor little devils yourself: Ebay auction.

The Ganzbot is a simple robot which can read your twitter feeds (or theoretically, somebody else's I suppose). This little robot is based on some RC servos, and an Arduino, and even comes with source code for the (cough) java interface to control it.

Looks like a nice simple weekend project, no? Video after the jump!

While not really designed for a sumo competition, this robot has entered the Matrix, with a real biological brain grown from rat neurons controlling it's actions.

Directed by Professor Kevin Warwick, The University of Reading is examining how neurons learn in the hopes of gaining a better understanding of development and of diseases and disorders which affect the brain such as Parkinson’s Disease, Alzheimer's Disease, stoke and brain injury.

To add to the overall creepiness, the brain itself is remotely controlling the robot over a bluetooth link.
