Revenge of the Fallen, the second installment in the Transformers movie franchise, is out this week and there’s no better way to celebrate than by geeking up your DS with these fancy costumes. If you’re into cosplay, maybe you and your DS can match.

The stylus and armor is available in both Bumblebee and Megatron and will cost you $19.99 for both, or $12.99 for either the stylus or the case.

Another week has come and gone. As usual, we’ve been keeping tabs on all things robot over at Botropolis. We haven’t had any reports of muscle-bound freaks appearing naked in the street and asking after John Connor, but hell, it’s only 2009. Still, we’re keeping our eyes peeled and we are your first line of defense. When they do strike, we will be ready with up to the minute updates. Here’s some of what we covered this week.

Magic: Octavia the robot gets fooled.

RoboFlush: For the extremely lazy.

T-Shirt: Robots In Disguise.

Fall Out Boy: New Robot Comic Books.

Nature is always the best model, whether you’re building robots or…other human made monstrosities. And with that in mind, Nissan has applied the idea to the Biomimetric Car Robot or BR23C. The robot car is modeled after Bee behavior in order to prevent car collisions and thereby eliminate accident casualties.

The BR23C adopts a bee’s eye view of the world. The insects rely on a 300-degree field of vision to identify obstacles and avoid them. Likewise the robot, using a Laser Range Finder (LRF) uses a 180-degree radius vision to detect obstacles two meters away. The image is transmitted to a microprocessor, which directs the robot to change direction or speed up in order to avoid a collision. In other words, avoiding collisions is all instinct.
