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 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.

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.

247 247  We now know how to manage sequences now lets see how you build one. As we said earlier a sequence is made up of frames. A frame represents a transition between robot states over time.
248 248  In addition to frames, you can also add other sequences to a sequence. This allows quite complex series of movements to be built up very quickly and easily.

The frame will record whatever position the robot is currently set to. You can add a sub sequence to the sequence by clicking the arrow to the right of the Add button. A drop list of the available sequences will appear. Select one and it will be added to the end of the sequence.

272 272  The timeline is locked by default. This means that frames will automatically run from one to the next – you cannot create space in between. Moving a frame past another one will move it along the order in the timeline. If the timeline is unlocked then you can move frames independently of each other and also create gaps of time in between.

276 276  To move a frame on the timeline, simply click on it and drag it to the time you want it to start. The start time will be displayed as you drag. How frames move relative to each other is determined by whether the timeline is locked (see previous section). To resize a frame grab the right-hand edge and drag it. When moving or resizing the mouse snaps to the nearest unit on the timeline. If you hold SHIFT while moving or resizing no snap will be applied. When the timeline is unlocked then if you hold CTRL while dragging or resizing a frame all frames to
