A Swarm of Nana Quadrotors
Impressive demonstration of extremely small and mobile flying machines that can perform complex movements together - you see the good stuff at roughly 56 seconds into the video.
Experiments performed with a team of nano quadrotors at the GRASP Lab, University of Pennsylvania. Vehicles developed by KMel Robotics.

A new global treaty could allow corporations to police what we do on the Internet. Last week we successfully pushed back the US censorship bills — if we act now, we can get the EU Parliament to bury this new threat — add your voice now!
Pythagoras
Developmental drawing robot sketches with pen, with open software for vectorizing images:
Pythagoras is a drawing delta robot. The goals for this robot was high speed and high precision pen work. OpenCV is used to vectorize images to send to the robot for sketching.
Current progress is on version 2.5. Drawing is successful and has high accuracy. The image processing program can tell the robot to either outline an image or shade it in.
Higher manipulator speed and accuracy using resolved rate path generation and Jacobians is in progress.
Potential further development includes using brushes instead of pens, a pen switcher for multiple colors, halftoning, and SVG support. More ambitious ideas include adding omniwheels on the legs so the bot can traverse large drawing areas.More information, images, and videos demonstrating how it works, can be found at aaronbot3000’s blog.
