旋转传感器#
介绍#
The Rotation Sensor measures the rotation of a shaft. It can be used anywhere on a robot where a shaft is rotating, even if that shaft is not connected directly to a motor.
A motor has a built-in encoder that can track its own rotation. The Rotation Sensor works like an external encoder that can track the rotation of a separate shaft.
The Rotation Sensor can report the shaft’s angle, position, and velocity. Angle is the shaft’s absolute position from 0 to 359.99 degrees. It does not reset when a project starts or when the robot is powered off. Position tracks how many degrees or turns the shaft has rotated forward or reverse during a project, and it can be reset as needed.
The Rotation Sensor is compatible with 1/8 inch and 1/4 inch standard VEX shafts.
以下是可用模块列表：
set Rotation position — Sets the Rotation Sensor’s current position to a specific value.
Rotation angle — Reports the shaft’s current angle from 0 to 359.99 degrees.
Rotation position — Reports how far the shaft has rotated in degrees or turns.
Rotation velocity — Reports how fast the shaft is rotating.
set Rotation position#
The set Rotation position stack block sets the Rotation Sensor’s current position to a value in degrees.
Position is how far the shaft has rotated during a project. Setting the position changes the current position value without moving the shaft.

描述 |
|---|---|
设备 |
The Rotation Sensor to use. Choose from the Rotation Sensors configured in the Devices window. |
位置 |
The position value to assign to the Rotation Sensor, in degrees. This can be an integer or a decimal. |
Rotation angle#
The Rotation angle reporter block reports the shaft’s current angle from 0 to 359.99 degrees.
Angle reports the shaft’s absolute position within one rotation. It does not reset when a project starts or when the robot is powered off.

Rotation position#
The Rotation position reporter block reports the shaft’s total rotational position.
Unlike angle, position can increase past 359.99 degrees or decrease below 0 degrees. Position tracks how far the shaft rotates forward or reverse during a project and can be reset as needed.
