14.1	10
47.1	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.
16.1	12
47.1	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 of the standard computer peripherals. and you can quickly create 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. 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.

16.1	24
15.1	25	= Initial Setup =
9.1	26
30.1	27	In order to understand the features, functionality and nuances of the Lynxmotion smart servos, it is suggested to read through the [[doc:lynxmotion-smart-servo.WebHome]] section of the wiki.
	28
	29	Before assembling the arm, each of the IDs assigned to the servos must correspond with what is needed in the software.
3.1	30
4.1	31	* Base: 1
	32	* Shoulder: 2
	33	* Elbow: 3
	34	* Wrist: 4
	35	* Gripper: 5
3.1	36
34.1	37	To do so, the [[LSS Configuration Software>>doc:lynxmotion-smart-servo.lss-configuration-software.WebHome]] is used. Follow the procedure outlined here: [[doc:lynxmotion-smart-servo.lss-configuration-software.lss-config-configure-ids.WebHome]]
30.1	38
34.1	39	Important note: The software does not take into consideration if a servo has been improperly assembled. If you see that your arm moves differently than the arm on screen, be sure to check the following:
	40
	41	* Servo ID is correctly assigned to each servo and there are no duplicate IDs
	42	* Servos have been assembled in correct orientation (as per assembly manual)
	43	* Servo offsets have been updated if necessary (see procedure below).

30.1	49	[[image:lss-flowarm-header.jpg]]
3.1	50
30.1	51	STORE OFFSETS
3.1	52
45.1	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]]). Before pressing the button, be sure to orient the arm as follows (with the gripper closed), and only then click the STORE OFFSETS button.

34.1	55	[[image:lss-flowarm-offsets.jpg]]
	56
30.1	57	LIMP
3.1	58
46.1	59	Causes all servos to go LIMP (i.e. lose torque). The arm will collapse. It's important to note that the software will not constantly query all servos for their position, and as such the virtual arm on screen will not update frequently if at all. If you want the arm on screen to update as you move the arm, use TEACH mode described below.
3.1	60
30.1	61	STOP
	62
	63	Causes all servos to stop their motion and hold their position.
	64
	65	TEACH
	66
46.1	67	Teach mode allows a user to physically move the arm to a designed locations and have the virtual arm on screen follow. This is used primarily to manually add frames to the sequence. 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.
30.1	68
	69	CAREFUL: Do not move the servos too quickly. We suggest moving the gripper servo, or temporarily removing the aesthetic shell.
	70
46.1	71	Once the arm is limp, it can be moved physically, and the application will regularly read the physical position of each of the servos and move the virtual arm on screen to match. Use the sequencer to save each position (frame). Intermediate frames can be added as needed. For more information on the sequencer, refer to the sequencer section below.
30.1	72
	73	GRID / Units
	74
46.1	75	Units can be toggled between Metric or Imperial units. Options include 2cm, 3cm, 5cm and 1in, 2in and 3in.
3.1	76
30.1	77	BAUD
3.1	78
31.1	79	The baud rate suggested is 115200, which is the default baud rate of the servos. Should a user have changed the baud rate on the servos, it can be selcted using the drop down. Note that the baud rate must be configured to the same value for all servos in order to work.
3.1	80
	81	COM
	82
30.1	83	This field selects which of your computer's COM ports is connected to the LSS Adapter, which is provided with the standard SES v2 articulated robot arm. Be sure to select the appropriate COM port to which the LSS adapter is connected. If you are unsure, go to Device Manager in Windows, and view the list of USB devices connected. The LSS Adapter uses an FTDI USB to serial chip.
3.1	84
30.1	85	When the software is opened, a scan of all COM ports is done automatically and list of all available COM ports will be found in the drop down menu, along with OFF (stop searching for a COM port), and AUTO (the application tries to automatically find the correct COM port by sending a query command at the corresponding BAUD rate).
	86
	87	If the red and green lights next to the field are flashing, the correct COM port has not yet been found, and the user may need to manually select the correct CIM port.
	88
	89	If the red light is solid, then no correct COM port has been located.
	90
	91	If the green light is solid, the a COM port has been located.

	103	The arm shown on screen is based on the assembly guide. BETA testers have been encouraged to use the 3:1 gear ratio in the shoulder and as such should have toggled switch 1 in the header.

3.1	122
46.1	123	Assuming the gripper has been properly calibrated, The number below represents the opening at the tip. Fully closed should correspond to 0 degrees.
45.1	124
46.1	125	In order to grasp an object, DO NOT have the servo rotate to a position which it cannot reach. Plan in advance:
	126
	127	1. Close the gripper to a position just slightly larger than the object
	128	1. Using the arrows, close the gripper until friction between the foam and the object prevent the object from falling out or moving.
	129	1. DO NOT apply too much pressure, or else the servo's current will spike and it will go into error mode.
	130	1. Use the last position as the "fully closed" position for the gripper for that object.

3.1	154
30.1	155	[[image:lss-flowarm-sequencer.jpg]]
3.1	156
45.1	157	LSS FlowArm has a powerful pattern sequencer component (normally found only in the full version of FlowBotics Studio) that is used to create reusable patterns within minutes, instead of hours or days. The sequencer also allows you to vary the speed of playback of a routine. From left to right:
