Series servos feature a contactless (Magnetic) position encoder and PID control for superior
accuracy and reliability. The MX series offers 12bit (4096) position resolution
and can operate in the 360º range offering 0.008º resolution.
Dynamixel Servos are connected using a Daisy Chain mechanism and are queried
and controlled with an advanced Serial protocol. Over 50
Read/Write parameters are available including Position feedback, Load feedback
and PID tuning.
