Note

These effort limits are nominal values. The actual limits are computed with the following formula:

\[\text{effort}_\max = \frac{\text{effort}_\text{max_nominal}}{\text{effort_correction}}\]

where \(\text{effort_nominal}\) is the nominal effort limit of a joint, \(\text{effort_correction}\) is the effort correction factor of this joint, and \(\text{effort}_\max\) is the actual effort limit of this joint.

The effort corrections can be retrieved with trossen_arm::TrossenArmDriver::get_effort_corrections().

Controller Base

The controller base has three M12 connectors with different functions.

Coding	Carries
X Code	Network
A Code	GPIO
L Code	Power

The base also has the arm’s power switch, a status LED, and a small screen that can display and manage the arm’s state and configuration.
