This smart servo from XYZrobot was designed for their Bolide Y-01 Advanced Humanoid Robot, making it well suited for applications that require a lot of strong and complex actuation, such as humanoid robots, hexapod robots, and robotic arms. Unlike common RC hobby servos, these servos are capable of 360° continuous rotation while still offering position control over an effective range of 330°. They feature a TTL serial interface that is used to configure and control the servo and get feedback about position, speed, and temperature.

Note: This is not an RC servo and does not use the same protocol, so they will not work with standard RC receivers and servo controllers.
