ኣደጋ INTERACTIVE SERVO MOTORS
The three Servo Motors give your robot the ability
to move. If you use the Move block in the
software to program your motors, the two motors
will automatically synchronize, so that your robot
will move in a straight line.
Built-in Rotation Sensor
Each motor has a built-in Rotation Sensor. This lets
you control your robot's movements precisely. The
Rotation Sensor measures motor rotations in degrees
or full rotations [accuracy of +/- one degree).
One rotation is equal to 360 degrees, so if you seta
motor to turn 180 degrees, its output shaft will make
half a turn.
The built-in Rotation Sensor in each
motor also lets you set different speeds
For your motors [by setting different
power parameters in the software]. Try
running the motors at different speeds.
