9 -The Lynxmotion Smart Servo (LSS) is a new, compact, modular and configurable actuator designed to be an evolution of the standard RC servo for use in multi degree-of-freedom robotics, animatronics, custom RC projects and more. The servo lineup currently includes three “smart servos” which appear physically the same, sharing the same dimensions, mounting points and output spline, but differing in maximum torque and speed, and . The servos are core modules of the next generation Lynxmotion Servo Erector Set (S.E.S.) modular robotic construction system and a wide variety of modular brackets, mechanics and electronics have been designed around them. "Smart" means each servos' parameters are user modifiable and configurable, there is sensor feedback, built-in safety features, and they are although meant to be connected to a microcontroller, can be used as advanced RC actuators. The custom LSS serial communication protocol was built upon the SSC-32 / 32U protocol and makes communicating with, controlling and configuring the servos easy and intuitive.
3 +The Lynxmotion Smart Servo (LSS) lineup currently includes three “smart servos” which differ in maximum torque and speed. The easiest way to differentiate between the three models is based on the sticker, located at the rear of the servo. Lynxmotion software automatically determines which model is connected.

11 -NOTE: The Lynxmotion Smart Servo motors, as well as the SES modular construction system is NOT open source. As such, RobotShop cannot provide the schematics for the electronics, nor any details relating to the components used internally. Opening the servos without the express permission from RobotShop will void the warranty.
