Abstract: An output torque calculation device and a method thereof is provided, and the output torque calculation device includes a first sensor, a second sensor, a rotor, a reducer, a processor, and an elastic device. An input portion of the reducer and an output portion of the reducer are respectively connected to the rotor and an input portion of the elastic device, and an output portion of the elastic device is configured to connect to a load. The output torque calculation method comprises: detecting a first angle of the rotor by the first sensor; detecting a second angle of the output portion of the elastic device by the second sensor; and calculating a torque carried by a final output end of the output torque calculation device by the processor according to the first angle and the second angle.
