The present invention discloses a servo control system and a robot. The servo control system is applied to a servo and includes a main control module and a driving module including a driving circuit and an electronic switch circuit. The driving circuit is coupled to the main control module. The electronic switch circuit is coupled between the driving circuit and a driving motor of the servo. Wherein, the driving circuit receives a control signal outputted by the main control module and outputs a driving signal according to the control signal. The electronic switch circuit outputs a driving pulse to the driving motor according to the driving signal, to control the rotation of the driving motor. In the above manner, it can be convenient for heat dissipation and strengthens the driving capability.
