  = Description =
  The Lynxmotion Servo Erector Set Professional (SES PRO) Arm Interface is a simple software which allows a user to control any of the Lynxmotion Professional Modular robotic arms in their default configuration. The two compatible gripper kits which are compatible with the SES PRO system (based on the DH Robotics PGE-50-40 and CGE-10-10 DC grillers) can also be controlled via this interface in each of their possible configurations. The included manual jog feature can be used to either position each joint angle, or move to specific cartesian coordinates. Arm (and gripper) positions can then be recorded as part of the built-in sequencer. A 3D display of the arm shows the position of the arm, and a graph can be used to show various information to the user. In order to get a better understanding of the protocol, commands sent to the arm are shown in the interface, and a user input field are standard.

--=== Payload Considerations ===
++Before proceeding with the guide, it is important to note the following:
--1. The rated payload for each arm does NOT include an end effector, nor any added distance between the center of mass of the payload and the output of the final joint. Each of the two compatible Lynxmotion PRO grippers reduce the maximum payload of each arm, and it is up to the user to known and understand the concept of "torque" and center of mass before adding an end effector and payload.
--1. The rated maximum payload for each arm (at full reach) is at the rated speed for each motor. Moving any joint at a higher speed will decrease the payload capacity of the robot.
--1. Although each servo can provide significantly more torque than is needed for the rated payload (and therefore means the arm can support much higher loads at lower speeds, the mechanical and modular structure of the arms may fail. We strongly suggest testing and using each arm in a highly controlled and safe setting where, if a failure should occur with one or more joints, that nothing will break should the arm fall.
--1. The stepper motors provide the highest torque at low speeds, and lower torque at high speeds. Note that the maxium torque is not at the lowest speed as the torque to rpm curve for each servo resembles a "mountain".

--=== Emergency ===
--
--Before using the arm, it is important that a user know what to do when an issue or emergency arises where the arm must be stopped quickly. The following emergency options are available based on severity:
--
--**Halt & Hold**
--
--This will stop every joints and hold them in their last recorded angular positions. The corresponding command is #254H<cr>.
--
--**Limp**
--
--All joints will go limp which mean there will be nothing avoiding them to turn freely (potentially causing the arm to fall). The high gear ratio of the strain wave gearing does mean there is some (low) level of resistant to rotation, but the gears and motor are nto "locked" and as such, the arm may fall. The corresponding command is #254L<cr>.
--
--**Software Stop**
--
--The E-stop button within the software sets all joints to limp.
--
--**Hardware E-Stop**
--A hardware E-stop (push to cut power) button is located on the power supply which will cut electricity to all actuators. Similar to a limp command, this can possibly cause the arm to fall. To reset this button, rotate the red "mushroom" in the direction indicated by the white arrows and it will spring out.
