This is a study group for the Control of Mobile Robotics class (https://www.coursera.org/course/conrob) which is a free class offered by the Georgia Institute of Technology.
The discussion will be driven by your input and can cover the material in the lectures, homework, programming assignments, and building the physical robot described in the class. If you are building the robot bring it along and we can test them and help debugging. There will also be people there that can help you get the robot working in an alternate configuration (e.g. using Raspberry Pi) since most of the specified parts are in short supply.
There will also be a robot available to test your code if you don't have one yourself.
