1. Dynamixel AX-12
The Dynamixel series robot actuator is a smart, modular actuator that incorporates a
gear reducer, a precision DC motor and a control circuitry with networking functionality,
all in a single package. Despite its compact size, it can produce high torque and is
made with high quality materials to provide the necessary strength and structural
resilience to withstand large external forces. It also has the ability to detect and act
upon internal conditions such as changes in internal temperature or supply voltage.
The Dynamixel series robot actuator has many advantages over similar products.
Position and speed can be controlled with a resolution of 1024 steps.
The degree of compliance can be adjusted and specified in controlling position.
Feedback for angular position, angular velocity, and load torque are available.
The Dynamixel series robot actuator can alert the user when parameters deviate from
user defined ranges (e.g. internal temperature, torque, voltage, etc) and can also handle
the problem automatically (e.g. torque off)
Wiring is easy with daisy chain connection, and it support communication speeds up to
1M BPS.
Position, velocity, compliance, and torque can be set with a single command packet,
thus enabling the main processor to control many Dynamixel units even with very few
resources.
The main body of the unit is made with high quality engineering plastic which enables it
to handle high torque loads.
A bearing is used at the final axis to ensure no efficiency degradation with high external
loads.
The LED can indicate the error status to the user.
A hinge frame and a side mount frame are included.
