Not enough to be able to build a complete bot running ROS on an Arduino, but enough to make it easy to use Arduino as part of a bigger system using ROS. A much more complete implementation will run on Andriod [in Java].
This 16:47 video includes many clips of quadracopters that have been posted here before, being talked about by a researcher from University of Pennsylvania researcher. The final ‘music video’ clip, I have not seen before.
Now here is a different remote control robot. A simple sphere that can be controlled by bluetooth. Video with link to article.
Now if these had any sort of external sensing [seems to have just internal gyroscope and accelerometer], how about a flock [fleet?] of them to be used as remote sensors for other bots? eyes and fingers. At $129 each though, that would get pricey fast.
The robotic car course adds to the previous course, but the previous courses is not a requirement. CS 373 assumes strong programming knowledge, but CS 101 does not need any previous programming background.
