11 11  The LSS FlowArm application is intended to allow easy control of the standard Lynxmotion Servo Erector Set (S.E.S.) v2 articulated robotic arm. The graphical interface shows multiple views of the arm which can be controlled via drag and drop, as well as by manually inputting coordinates. The full-featured built-in sequencer allows you create sequences which have the arm move automatically from one position ("frame") to the next. Make use of the "teach mode" to position the arm where you want and record frames which can be modified and played back. Associating each pattern with input keys means you can easily play back and test multiple sequences.

13 -FlowBotics Studio was used to create this app and includes hundreds of built-in components that allow you to interface your PC to many standard computer peripherals and robotics components, and you can quickly design new components for new hardware. Easily create new projects with custom GUI screens, knobs, buttons, switches, etc. that will run live from within FlowBotics Studio without needing to wait for compilation, or export as stand-alone executable files. FlowBotics Studio includes a powerful graphics engine that allows you to make custom graphical objects by using standard bitmaps or by drawing your own shapes on the screen. Using this system, you can build entirely custom interfaces like this one for your projects and integrate photographs, drawings, and graphs.

Before pressing the button, orient the arm as shown below (with the gripper closed), and only then click the STORE OFFSETS button.
53 +During the assembly process, if the servo's driving output horn was not rotated (they are shipped with the servo driving horn centered at 0 degrees), and was connected to the brackets at the correct angle (parallel or perpendicular depending on the servo being assembled), there should not be any significant servo offset needed and the arm should match what is displayed on screen. However, should the driving horn have rotated and/or the brackets were not connected at optimal angles, the "STORE OFFSETS" button configures the all of the servo offsets (this makes use of the CO command as part of the [[LSS Communication Protocol>>doc:lynxmotion-smart-servo.lss-communication-protocol.WebHome]]).

73 -Teach mode allows a user to physically move the arm and have the virtual arm on screen follow. This is used primarily to manually add frames to sequences, determine the optimal closed position for the gripper etc. In order to ensure the arm does not collapse, pressing the TEACH button will start a 5 second countdown during which the arm will slowly lose torque (angular force) until all servos are limp. When in teach mode, an orange outline appears over all on-screen fields which would cause a conflict and therefore cannot be used.

Select which of your computer's COM ports is connected to the [[LSS Adapter>>doc:servo-erector-set-system.ses-electronics.ses-modules.lss-adapter-board.WebHome]] (which is provided with the standard SES v2 articulated robot arm). If you have a list of available COM ports and are unsure which is associated with the LSS Adapter, go to Device Manager in Windows, and view the list of USB devices connected. The LSS Adapter uses an FTDI USB to serial chip. Alternatively, simply unplug the USB from the arm and see which of the COM ports disappears from the list.
