The invention discloses a system and method capable of displaying postures of a robot in real time. The system capable of displaying the postures of the robot in real time comprises a posture sensor, a plurality of joint steering engines, a MCU, a display device and a battery, wherein the posture sensor, the multiple joint steering engines, the battery and the display device are connected with the MCU. The method capable of displaying the postures of the robot in real time includes the following steps that (1) the posture sensor obtains and provides a real-time state value of the body part of the robot for the MCU; (2) the multiple joint steering engines obtain and provide real-time movement angle numerical values of all joints of the robot for the MCU; (3) the MCU works out and simulates the current real-time movement state of the robot according to the body state value and the real-time movement angle numerical values; and (4) the display device displays the real-time movement state, worked out and simulated by the MCU, of the robot in real-time. The system and the method can display the postures of the robot in real time, and data of the postures of the robot can be further used for other analyses and applications.
