Design Challenges 5 © 2008 RoboRubik Size constraint Power consumption Component analysis Circuit debugging Component failure

Project Demonstration 6 © 2008 RoboRubik An ability to: control device state/configuration via an embedded web page display cube “state” via a series of integrated (multi-color) LEDs change cube “state” via a pushbutton on each face autonomously solve cube from arbitrary (user defined) initial state provide “hints” when solving the cube in “manual” mode
