We can only drive and program our robot when the simulator is running.

To turn the simulator "on", press the Play button and begin driving the robot using the W, A, S, D keyboard keys.

A green band will appear at the top of the screen to let you know that the simulator is "on". As each key is pressed, it will become highlighted in the on-screen display, and the robot will move in the specified direction.

W = moves the robot forwards          
= moves the robot backwards
A = turns the robot left
D = turns the robot right
