How to Track Objects in All Directions with the mBot2 Smart Camera

🎥🤖 Want your mBot2 to follow a ball in all directions — forward, backward, left, and right?

In this tutorial, we’ll extend the original ball tracking project and upgrade it into full 2D tracking. Using the Smart Camera add-on, you’ll learn how to combine vertical and horizontal error minimization so your robot can center the ball anywhere in its field of view.

You’ll learn how to:
✅ Review the forward/backward ball tracking program from the last tutorial
✅ Understand error minimization on both the X and Y axes
✅ Create new variables for center X, ball X, and scale factor X
✅ Use forward power and turn power together for precise wheel control
✅ Combine left and right wheel logic for smooth all-direction tracking
✅ Test and refine the complete program in mBlock
