运动

介绍

GO Motion commands let motors spin, hold position, and control velocity and torque with precision.

For the examples below, the configured motor will be named arm. They will be used in all subsequent examples throughout this API documentation when referring to Motor class methods.

以下是所有方法的列表：

动作——控制电机的运动。

• spin – Spins a motor in a specified direction indefinitely.

• spin_for – Spins a motor for a specified distance.

• spin_to_position – Spins a motor to an absolute position.

• stop – Stops a motor.

改变器——改变电机的不同属性。

• set_velocity – Sets the default velocity for the motor.

• set_max_torque – Sets the maximum torque for a motor.

• set_position – Sets the motor’s position to a specific value.

• set_stopping – Sets the stop behavior (brake, coast, or hold).

• set_timeout – Limits how long a motor function waits before giving up if movement is blocked.

Getters – 从电机返回数据。

• get_position – Returns a motor’s current position.

• get_velocity – Returns a motor’s current velocity.

• get_current – Returns the current being used by a motor.

• is_stopped – Returns whether a motor is currently not spinning.

• is_moving – Returns whether a motor is currently spinning.
