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.
