Me and my friend are currently working on 2 projects for 2 different classes. We are creating a robot mouth out of a 24x6 LED array and using a webcam to detect whether people are around and where they are positioned, the robot plays an audio file and creates a pattern on the LED matrix.
We are also working on creating a dancing claptrap unit from the game series Borderlands.It will basically bounce and move it's arms to create a dancing effect.
