Abstract: The present disclosure relates to robot technology, which provides a footed robot landing control method and device. The method includes: detecting a landing motion state of the robot; if the landing motion state is a flight phase descending state, a motion of the foot portion of the robot with respect to a ground in the flight phase descending state is controlled based on a relative speed; if the landing motion state is a support phase landing state, a motion of joints of the robot in the support phase landing state is controlled based on a first expected joint torque. The present disclosure is capable of reducing the impact of the foot portion against the ground, thereby realizing the flexible control of the landing process of the footed robot in a simple and rapid manner and reducing the cost of the footed robot.

Abstract: The present disclosure is applicable to robot technology. A method, an apparatus and a terminal device for robot fall prediction are provided. The method includes: searching for a gravity center offset weighting value corresponding to a posture of a robot; correcting a gravity center offset of the robot basing on the gravity center offset weighting value; correcting an acceleration of the robot basing on a gravity center offset direction of the robot; and determining whether the robot will fall or not basing on the corrected gravity center offset and the corrected acceleration. The present disclosure improves the real-time performance and accuracy of the prediction for the fall of a robot through the fusion calculation of various data.

Abstract: A brushless servo includes a housing, a motor, a printed circuit board (PCB), a servo output shaft and a gear transmission mechanism that are accommodated within the housing. The motor includes a motor output shaft that is arranged in parallel with the servo output shaft. The gear transmission mechanism includes a number of gearsets that connect the motor output shaft to the servo output shaft. Each gearset has a gear and a pinion that is smaller than the gear, and each of a first one of the gearsets and a last one of the gearsets is arranged in a manner that the gear is below the pinion thereof. Each of the rest of the gearsets is arranged in a manner that the gear is above the pinion thereof.

Abstract: The present disclosure relates to an anti-shake method of robot and a robot thereof. The method includes: receiving at least one motion-controlling instruction from a main control unit, determining whether a servo performs the motion-controlling instruction, obtaining a target angle and a current angle of the servo upon determining the servo is not under a control of a main control unit, determining whether the target angle and the current angle is within a fault tolerance range, terminating the servo upon determining the target angle and the current angle is within the fault tolerance range. As such, the shaking of the robot may be avoided when the robot performs actions, so as to reduce power consuming and to extend stand-by time.
