Abstract: A robotic hand includes a servo housing, a printed circuit board (PCB), a motor, a planetary gear transmission assembly and a plurality of claws rotatably connected to the servo housing. The motor is electrically connected to the PCB. An input end of the planetary gear transmission assembly is connected to an output shaft of the motor, and an output end of the planetary gear transmission assembly includes a helical gear shaft and a number of helical gears that are engaged with the helical gear shaft and the claws. The helical gears correspond to the claws respectively. One end of each of the claws is rotatably connected to the servo housing, and the claws are rotatable toward or away from one another when driven by the helical gears.

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 robotic hand includes a servo housing, a printed circuit board (PCB), a motor, a planetary gear transmission assembly and a plurality of claws rotatably connected to the servo housing. The motor is electrically connected to the PCB. An input end of the planetary gear transmission assembly is connected to an output shaft of the motor. An output end of the planetary gear transmission assembly includes a cam having a number of protruding portions in a circumferential direction thereof. Each two adjacent protruding portions are spaced apart from each other by a space, thereby forming a curved circumferential surface. One end of each of the claws stays in contact with the curved circumferential surface, enabling the claws to be rotatable toward or away from one another when driven by the cam.
