Actuators, robots equipped with actuators

Abstract

One of the objectives of the present invention is to provide an actuator that is less susceptible to electrolytic corrosion. [Solution] The actuator 100 is an actuator having a motor 1 including a rotor 3 and a stator 2, and a transmission 4 that rotates using the output of the motor 1 as input, wherein the transmission 4 includes a vibrator bearing 42, and a low-conductivity means 18 made of a material with lower conductivity than the rotor 3 is provided between the rotor 3 and the vibrator bearing 42, and the electrical resistance between the rotor 3 and the vibrator bearing 42 is greater when the low-conductivity means 18 is present than when the low-conductivity means 18 is not present.
