Lynxmotion's Servo Erector Set Professional (SES-PRO) modular robotic construction system can be used to create anything from powerful pan and tilt systems to five or six degree of freedom articulated robot arms (such as the SES Pro Modular Robotic Arms) and manipulators to large legged robots. The core of the system comprises three all-in-one smart servo motors which can provide very high torque at high angular precision. Despite being professional, they are easily configured and the communication protocol is human readable.
