REV Smart Robot Servo (SRS)


goBILDA Dual Mode Servo


Hitec Conventional Servo


A servo is a type of device that takes a Pulse-Width Modulated (PWM) signal as an input and, with the help of an embedded controller, produces linear or rotational movement based upon the input signal. Servos may take an input signal generated by a REV Hub (either by a Control Hub or Expansion Hub) which itself provides 5V of power and a limited amount of current (see REV Documentation for more information). A REV Servo Power Module (SPM) may be utilized to boost the power provided to servos to a maximum of 90W at 6V for up to 6 servos per device. Robots in FIRST Tech Challenge may employ up to 12 total servos.
