Creating a Square with Sphero

This tutorial guides you through creating a program to make a Sphero robot roll in a square. It starts with setting up the program canvas and selecting the appropriate blocks. You learn to use roll blocks to control the robot's movement, adjusting speed and duration for each side of the square. After running the program, you observe the robot's path and make adjustments to achieve sharper corners by adding delays. Finally, you view the JavaScript code generated by the block-based programming.
