    Abstract: A brake assembly for a servo including a motor includes: a brake disk fixed to and rotatable together with the output shaft of the motor of the servo, the brake disk having a lateral wall defining at least one opening; and a linear motion actuator including a plunger and an elastic member. The plunger sides from a first position where a first end of the plunger is received in the at least one opening to a second position where the first end of the plunger is disengaged from the brake disk when the linear motion actuator is energized. The elastic member applies an elastic force to cause the plunger to slide from the second position to the first position when the linear motion actuator is deenergized so as to stop rotation of the output shaft of the motor.

    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 includes a housing, a motor, a printed circuit board (PCB) and a servo output shaft that are accommodated within the housing. The motor is electrically connected to the PCB. The housing has a lateral side defining a cutout. The servo further includes a gear transmission mechanism and an output arm. The gear transmission mechanism is used to connect a motor output shaft of the motor to the servo output shaft. The output arm has an end that is arranged within the housing at a substantially central position and connected to the servo output shaft, and another end extending out of the housing to connect with an external component.

    Abstract: A servo and a robot with the servo are provided. The servo comprises a power input apparatus with a first output shaft, a deceleration apparatus, and a power output mechanism. The deceleration apparatus comprises a first-stage deceleration mechanism and a second-stage deceleration mechanism. The power output mechanism comprises a second output shaft and an output bearing fixedly installed on the second output shaft, wherein the second output shaft is an external spline output shaft. Through the external spline output shaft and the output bearing disposed on the power output mechanism, the servo could directly connect with an exterior component through the external spline output shaft, and the strength is improved. As a result, the friction between the servo and the exterior component is reduced, and the lifetime is therefore increased.

    Abstract: A head mechanism includes a base connectable to a body of a robot, a mounting member arranged above the base, a connecting member rotatably connected to the base and the mounting member. The connecting member, together with the mounting member, is rotatable relative to the base about a first axis, and the mounting member is rotatable relative to the connecting member about a second axis. The first axis and the second axis extend in different directions. The head mechanism further includes two first actuating mechanisms fixed to the base, and the two first actuating mechanisms are configured to drive the mounting member to rotate with respect to the base.

    Abstract: A robot joint configuration determining method, a robot using the same, and a computer readable storage medium are provided. The method includes: simulating a joint model of a first joint of the robot using first motion deviation data to obtain first result data; simulating the joint model using second motion deviation data to obtain second result data; taking the motion deviation data corresponding to one of the first result data and the second result data meeting one or more preset conditions as a target motion deviation data for the first joint; and determining type information of a reducer in a configuration information of the first joint based on the target motion deviation data. In the present disclosure, the motion deviation of the first joint that is relatively accurate can be obtained through the results of the two simulations.
