Dynamixel
A series of smart servos introduced by the South Korean company ROBOTIS, widely used as joint actuators in research and educational robotics. The series is characterized by high communication rates, extensive feedback registers, and mature SDK support.
Timeline (last 90 days)
Dynamixel is a smart servo series launched by the Korean company ROBOTIS.
The nominal speed of the ST3215 servo is still lower than that of the Dynamixel series used in the Doggo prototype.
Serial bus servos (such as Dynamixel or the domestic Feetech SCS series) communicate in series over a single bus and can read back position, speed, temperature, and load current in real time.
The Dynamixel product line from Robotis covers a torque range from 0.2 N·m to 44.7 N·m, spanning the AX/XL series to the industrial-grade PH/PM series.
Dynamixel servos use a TTL/RS485 bus-based serial communication protocol, allowing multiple servos to be daisy-chained on the same bus, with the protocol supporting addressing of up to 253 devices.
The bidirectional communication capability of Dynamixel servos enables real-time reading of each servo's position, speed, load, temperature, and input voltage parameters, enabling closed-loop motion control.
The retail price of some Dynamixel servos may be 3 to 5 times the estimated manufacturing cost, and finished robot manufacturers can significantly reduce the per-component cost through bulk purchasing advantages.
Risks of disassembling finished robots to extract Dynamixel servos include damaging JST connectors, encountering custom firmware that locks parameters or changes the baud rate, and parts being incompatible with other projects.
BAM can systematically calibrate and model common servo motors (such as the Dynamixel series), covering parameters including torque-speed curves, control latency, gear backlash, and thermal characteristics.
Dynamixel uses bus-based communication (TTL/RS485), allowing multiple servos to be daisy-chained in series, enabling precise feedback and control of position, speed, and current.
