  2. Contents • Overview of system • Achievements • Current Status • Way forward • Challenges • Summary

  3. Overview of System

  4. Overview of System Set-up Attachment Performance Sensors Data Link DAQ card Filtering Manipulation Display

  5. Progress Report

  6. Achievements • Systems Process established • Support • webpage • Research into field of Human Science • Science Report • System Level Specifications • PC, DAQ Card, Use of Labview, sensors • Purchased equipment • 1st prototype of labview

  7. Current Status of WIP • Labview manipulating data from sensors and displaying wire frame. • Sensors • Decided on use of potentiometers • Specific potentiometer not chosen (prototyping between digital & analogue) • Attachment method not decided.

  8. Way forward • Attachment investigation (following on from science report). • Prototype of multiple sensors (Wk 5) • Labview • User interface • Set-up programme (BIT) • Connectors • Sensors to DAQ card interface

  9. Challenges • Attachment of sensors • Suitable user interface • Timescale - Outline design slip. • Animation • Labview not being good enough • Cost of animation packages • Unplanned effort required to utilise animation package

  10. Conclusion • Background knowledge established • Systems process in place & working • Key hardware acquired • Outline design near completion We have planned the work… ...now we need to work the plan

  11. Questions

  12. Outline Design • Built in test • Input limb lengths Set-up • Frame • Support Attachment • Wire wound rotary potentiometer • Support Sensors • Standard wiring • Junction box Data Link DAQ card • Possibly not required? Filtering Manipulation Display

  14. Design assessment New requirements identified Limitations Interface consideration Identify possible solutions Identify Requirements to fulfil New requirements identified • Requirements INPUT More possible solutions • Investigation • Research • Prototyping NO Fulfil requirements? Requirements unrealistic? NO YES YES • Requirements • Raise Risk OUTPUT System Design Review OK? NO YES • Next Level of Design • Raise Risk Issue Design Decision OUTPUT
