NXT TECHNOLOGY

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 set a

motor to turn 180 degrees, its output shaft will make

half a turn.

Test it!

Test the built-in Rotation Sensor's ability to measure distance:

Connect a motor to the NXT.

Select the View submenu in the NXT's display.

Select the Motor Rotations icon.

Select the port where you have

connected the motor.

Now attach a wheel to the motor and measure the rotations as you roll the wheel along the ﬂ oor.

Select the Try Me submenu on the NXT's display and test your

motors. You'll get a fun reaction.

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.
