Let’s have a robo soccer competition among the groups of students where two teams can compete
with each other.

As the Robo-Soccer match heated up, your robot stumbled, failing to keep the ball in check. Frustrated,
you paused to think about its design. Could adjusting the weight distribution or enhancing the wheel
traction help improve ball control? With a spark of inspiration, you began sketching new ideas to
ensure your robot would dominate the field.
While working on your line follower robot, you noticed it consistently veered off course, straying from
the black line. Puzzled, you took a moment to troubleshoot. Were the IR sensors misaligned, or was
the surface not contrasting enough? Determined to solve the mystery, you decided to carefully check
the programming and make adjustments to get your robot back on track.
