The AX-12A is a Serially Controlled servo that provides some 50 commands and feedback parameters to allow complete control over your robot application.
The Serial protocol is daisy chained, meaning several servos can be connected to each other in a chain and offer several compliance and sensing parameters that can be configured and read including position, velocity and temperature.
BT-410 is a device that enables serial communication (UART) via Bluetooth communication.
BT-410 covers the circuit with a case to protect it, and it uses a connector-type cable to install on a robot and RC-100B.
You can control your robot without any problems even when the infrared control condition is not optimal such as in a robot competition.
The SLAVE module can be used when controlling the robot from a smart device that supports BLE (Bluetooth 4.0 Low Energy) communication.
