In a word, don't rotate the arm 180 degrees, because that hammers the ball into the ground.
To make the ball fly high in the air, the arm should stop early. Probably, it should stop after it has rotated 45 or 90 degrees compared to its initial position. However, if you rotate the arm more than 90 degrees, you will aim the ball down to the ground and not up in the air.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
Level A2. "Space exploration". Robotics with LEGO
The second level of the Robotics with LEGO curriculum for students in second, third or fourth grades.
A new sensor is introduced - the Ultrasonic distance sensor can help the robot avoid obstacles. Students work with new concepts like loop, degrees and medium motor. Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles. The first robot with chain-treads is built.
