As great as RobotC is, the one thing that its users have consistently complained about is the lack of good tutorials that go beyond the simple “move motorA at 20% speed”. Well, rather than waiting for the CMU Robotics Academy to come up with one, Albert Schueller, one of the professors from Whitman College, has written an excellent course called “Programming with Robots” based on RobotC.
It covers all the bases, variables, conditionals, loops and arrays, you name it. Each new concept is accompanied by example code and every chapter ends with a series of exercises that you can use to test if you have grasped the new concepts covered thus far.
