Critical Design Review

This presentation discusses the integration of Bluetooth technology in handheld PDAs to control robotics effectively. We outline our project's progress, address scheduling updates, and discuss potential challenges, such as the lack of hardware components and Bluetooth adapter availability. The system utilizes Microsoft Embedded Visual C++ and incorporates features like an on-screen joystick, interactive maps, and sonar displays for user-friendly interfaces. We aim for seamless communication between the Pocket PC and the robot, facilitating robust control and positioning capabilities.

  1. Bluetooth Robot Control with a PDA Critical Design Review Ta-Chang Chao,Quang Dang Matt Dean, Brady Wied

  2. Introduction • Problem: Allow a handheld PDA to act as the brain for a robot with Bluetooth technology. • Today’s Presentation: Project Status, Scheduling Updates, Potential Problems, Questions

  3. Knowledge Development/Training • Microsoft Embedded Visual C++ 3.0 • Pocket PC Emulator • Microsoft Foundation Classes • ActivMedia Robotics Interface for Applications(ARIA) • GAPI Draw • Bluetooth Communications Protocol

  4. Porting ARIA to the Pocket PC • Large amounts of functionality needed • Pocket PC port did not yet exist • Many common features of C++ were not implemented by eVC++ • Alternate STL and Winsock libraries

  5. ARIA DLL Production • Provide a common linkable library to application developers • Removes need to recompile the ARIA library every time an application is made. • Incorporate into our example robotics application

  6. User Interface Development • Sonar Display • On Screen Joystick • Interactive Map • Component Integration

  7. User Interface Development

  8. Pocket PC to Robot Communication • Waiting on Bluetooth adapter • Successful connectivity with a wired TCP/IP connection. • ARIA designed to allow easy conversion between communication classes (types). • Voltage regulator to supply Bluetooth adapter with power.

  9. Control of Robot Simulator Using PDA Emulator

  10. Developing the Robot Application • Currently planning two main features:1. Move the robot with an on screen joystick or by pointing on the map.2. Corrective positioning using the map.

  11. Potential Problems • Not all hardware components have arrived (robot, Bluetooth serial adapter) • Serial connection via the Bluetooth adapter

  12. Updated Schedule *Completed tasks shown in red

  13. Conclusion • Ahead of schedule • Continue to work hard on our subprojects • Work with the actual hardware instead of emulators • Coordination of efforts to bring the various modules together
