Innovative STEM Tool for Kids: iRobot Programming Interface

Our team created a fun, educational interface to teach elementary students programming for iRobot, focusing on navigation, sensor control, loops, sounds, and lights. Achieved goals include new requirements and risks identified and a functional prototype developed. The project aims to excite students about STEM fields and streamline iRobot programming. Operating on Windows, using C#, and offering a drag-and-drop GUI for easy programming.

  11. Capability Goals • OC-1 Navigation programmability: Fun-to-use interface to help elementary school children learn programming to control navigation of iRobot. • OC-2 Sensor programmability: Fun-to-use interface to help elementary school children learn programming to control navigation of iRobot. • OC-3 Loop and wait constructs: The interface shall allow drag & drop of programming constructs like if-then-else, for and while loops. • OC-4 Sounds and light programmability: The interface shall allow drag & drop of musical notes and LED on/off instructions. • OC-5 Demo mode programmability: The interface shall allow drag & drop of pre-programmed demo modes. 10

  12. Levels of Service Goals • LOS-1: Seamless interoperability between GUI and compiler. • Win condition: The system shall generate instructions for iRobot in C which is then later compiled for deployment on the microcontroller using the APIs of iRobot. • Measure: Number & severity of faults found in code generation & compilation modules. • LOS-2: Detect and report ambiguous instructions in an understandable way. • Win condition: The system shall detect and show logic errors (conflicting/inconsistent instructions) in a easy-to-understand way. • Measure:Feedback from stakeholders like undergraduate students and elementary school teachers on the framed help & error messages. • LOS-3:Reasonable frequency of reading sensor data. • Win condition: The system shall enforce a tolerance limit of +/- 2 to 3% error in angle of turning. • Measure: Manual testing and recording results for variety of sample inputs. • LOS-4:Portability above Windows 7 • Win condition: The system shall be a native windows 7 and above application. • Measure: Regression test results on the windows versions above 7. 11

  13. Organizational Goals • OG-1:Generate more excitement toward STEM fields. • OG-2:Widen the user sector for iRobot. • OG-3:Improved understanding in students about logic and control systems. • OG-4:Decrease time needed to program iRobot to execute complex instruction set. • OG-5: Use of iRobots to improve funding opportunities for Mission Science. 12

  14. Constraints • CO-1:Windows as an Operating System: The new system must be able to run on Windows 7/8/8.1 • CO-2: Zero Monetary Budget: The selected NDI/NCS/COTS should be free or no monetary cost. • CO-3: C#as a Development Language: Visual studio C# will be used as a development language for the Drag & Drop GUI interface. 13
