Characteristics
The Bioloid Kit features a CM-5 controller, Dynamixel AX-12+ servos and a Dynamixel AX-S1 distance sensor. The CM-5 is connected to the servos and sensors using a bus connecting all devices through a daisy-chain network. It can also be connected to a computer using a serial connection, giving access to many different ways of dealing with the robot.
The CM-5
The controller used on this robot is a CM-5, which uses the processing ability of an ATMega128. It runs at 16MHz, 128Kb of Flash memory, 4Kb of EEPROM and 4Kb of Internal SRAM. It has two available UARTS, which are designed for communicating with the servos at 1Mbps and with the PC at 57600bps. The original firmware allows different programming methods using the Software from Robotis (more details further down), but it is possible to build our own firmwares, programming in C or C++ and compiling using the right libraries (more details further down).can You can find the
The Dynamixel AX-12+
This servos feature a precise position and speed control, an alarm system for different malfunctions, holding torques up to 18.6 Kgf.cm and communication speeds up to 1Mbps. It uses a simple communications protocol that allows writing and reading different status values (current and goal position, current and goal speed, LED status, torque, voltage, temperature, etc). Each servo has a different ID and this network doesn't allow multiple packets to be exchanged at the same time. An instruction and status packet must have the following structure:
| Instruction | 0xFF | 0xFF | ID | LENGHT | INSTRUCTION | PARAMETERS | CHECKSUM |
| Status | 0xFF | 0xFF | ID | LENGHT | ERROR | PARAMETERS | CHECKSUM |
