The Scribbler bot
The scribbler bot is essentially a drawing machine that converts digital information into a physical drawing. The bot is made up of a software component and a hardware component. The software component analyzes a picture taken by a web camera (or just about any other image source), creates a unique line drawing from that analysis, and exports a point list that corresponds to the points that make up the lines.

RC model helicopter prices have reached a point where all sorts of challenging (i.e. crash-prone) robotics projects become affordable. This document explains how to build a 300 g, 3D-capable helicopter with embedded Linux and Bluetooth datalink for less than 500 EUR. As a proof of concept, we provide software which allows the helicopter to be remotely controlled over Bluetooth with a PC joystick. Future work will focus on the integration of sensors (IMU, altitude, magnetic compas, GPS, camera) and flight control software (either third-party or dedicated). [
