Status Packet Result

NO ERROR

You can verify the Torque Enabled status by trying to move the output of the actuator by

hand.

Dynamixel actuator with an ID of 0

Compliance

The Angle Error and Torque Output can be represented with the following graph.

X:Angle Error

Goal Position CW

CCW

Even if the position deviates a little from the goal position in the CW direction, a large

amount of torque is generated in the CCW direction to compensate for this. However,

since inertia must be considered, a realistic implementation differs from this approach.

Considering this, the given conditions can be represented by the following graph.
