Abstract: The present disclosure provides a robot servo jitter suppression method and device. The method includes: counting an amount of reciprocating jitter of an angular position of an output shaft of a robot servo in a predetermined period, after the robot servo enters a lock position state for a first predetermined period; determining whether the robot servo is in a jitter state according to the amount of the reciprocating jitter of the angular position of the output shaft of the robot servo and a predetermined fluctuation value; and suppressing the jitter of the robot servo by adjusting control parameter(s) of the robot servo, in response to the robot servo being in the jitter state. The robot servo jitter suppression method and device solve the problem of the jitter of the robot servo appears when the virtual positions of the robot servo and the robot joint structure are not properly controlled.

Abstract: The present disclosure provides a wireless positioning method as well as a server and a storage medium with the same. The method includes: obtaining a current ranging value between a first positioning device and a second positioning device, where there is no obstruction between the first positioning device and the second positioning device; determining a distance of the first positioning device and the second positioning device in a depth direction of a tunnel based on the current ranging value; and obtaining a current coordinate of the second positioning device based on the distance. In the above-mentioned manner, the automatic updating of the coordinate of the reference base station in the tunnel can be realized, the times of repeated measurements of the base station are reduced, thereby improving the construction efficiency of the tunnel and saving working loads.

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: A servo movement control method, device, and terminal device are provided. The method includes: controlling an output shaft of the servo to rotate according to a first motion instruction; detecting whether a second motion instruction is received within a first preset time period, and re-planning a second target motion curve to a second target end position from a corresponding target position on a first target motion curve when receiving the second motion instruction; and controlling the output shaft to rotate from an actual position when receiving the second motion instruction to the second target end position according to the second target motion curve. When the second motion instruction is received, the servo is controlled to rotate from the target position to the second target end position according to the second motion instruction, so that the servo is switched from the first motion instruction to the second motion instruction smoothly.
