12. 1. Power calculations, Background research and British Standards.

13. 2. Cleaning method used. Combination of a rotating brush and a vacuum cleaner

14. 3. Design procedure followed. Step 1. Step 1. Transform any component we use into 3D model in AutoCAD.

15. 3. Design procedure followed. Step 2. Step 2. Designing the main frame around the components.

16. 3. Design procedure followed. Step 3. Step 3 . Design the containers using the remaining space .

17. 3. Design procedure followed. Step 4. Step 4 . Design of the exterior parts.

18. 4. Materials Used Main frame MDF for model, ( Polycarbonate PC) 3 Parts joined together. Vacuum forming. Containers P olystyrene for model (ABS ) 4 Parts joined together. Vacuum forming. Exterior P olystyrene for model ( Polycarbonate PC) 3 Parts separate. Screwed onto the frame Vacuum forming .

19. 5. Testing Two main problems 1. Burning 2. Broken drive motor

20. Navigation System Selection of the navigation strategy Brief explanation of the navigation system design Evolution of the final navigation system

21. Navigation Strategies Command Instruction navigation strategy E.g. Remote control driven Global Path Planning strategy E.g. Map based system Reaction / Behaviour-Based System E.g. Sensor Information Reaction System

22. Reason For Choosing Project aim to develop a autonomous floor cleaning robot Limitation of the controller board (money and processor) and the project beget Sensor information reaction system is a more practical option

23. System Design Obtain environment information from 3 groups of sensors Front Sensors Side Sensors Left side Right side Group Sensors

24. Evade The Frontal Obstacle Detect the obstacle position Turning with different direction and degree B Turn Right 30 o B Turn Right 75 o

25. Walk Parallel With The Wall Detect the distance from wall Turning until parallel with wall

26. Stop in edge Detect depth changing Stop all the movement

27. Evade/escape the obstacles efficiently Performance is stable No programming deadlock occur Cannot guarantee clean the whole room Evaluate the navigation system

28. Power source selection Power consumption Battery’s capacity Battery’s type Ni-cd, Ni-mh , Li-ion and SLA(seal lead acid)

29. Design Bumper sensor Floor sensor Infra red range detector

30. Hardware (Circuitry) OOPIC microcontroller compact size 2.5 x 3.0 inch 16 Digital I/O lines for general usage H-Bridge Dual channel H-Bridge Up to 40watt DC motor per channel Embedded circuit
