NXT motors & Control Block

• The NXT servo motors have a built-in rotation

sensor block that continuously measure and

monitors the degrees covered by the motor.

• Motors can be manipulated using the move,

motor, and reset blocks.

• The move block synchronizes motor to enable the

robot to move straight.

• The move block can control all 3 motors

simultaneously. However the power is shared

among the 3 motors.

• The block has a built-in system for error

correction.
