14. 14 Student Teams SETTING UP TEAMS  A questionnaire is useful to determine students’ background (electrical, mechanical, written and oral communication skills, creativity, wood working, etc)  Assign specialties to each team. Switch students with specialty if necessary

15. 15 Student Teams STUDENTS WILL EXPERIENCE PROBLEMS: They are DESIGNED in! TEACHERS’ APPROACH  Know all about the project, but don’t solve problems!  Decide how much to share with students and what they should discover for themselves.  Automation Kits – Please return automation boards and interconnection cables.

16. 16 Student Teams Have students log everything:  For things that go wrong, include the problem and a description of attempts to solve the problem, including failures.  Present regular status of progress to class as part of semester grade.

17. 17 Building the Robot

18. 18 Your Robot Kit Kits are to be built with TWO LEGS Robot is designed and built and then electrically wired Assembly time is approximately two-three months based on 3 hours per week. Average of total time is 25 hours.

19. 19  Required - not provided  wood saw  jig saw  electric drill  needle-nose pliers  screw drivers  sharp knife  batteries  tools and materials to create a robot body covering that does not interfere with mechanical operation  sand paper (wood & metal)  25 watt soldering iron  safety goggles  extra blocks of wood  small vise with rubber jaws (for threaded rods)  wire cutter and stripper Building the Robot - Tools

20. 20  Dremel tool (rotary cutting tool) for cutting the threaded rods (cutting rods at 40K RPMs)  Bench drill press is helpful for aligning holes  Miter box  Multimeter (multitester, VOM) to check electrical circuits Building the Robot - Tools  Optional - Not Provided

21. 21 Building the Robot - Safety Use safety glasses at all times when drilling and/or cutting Protect desk or work surface If using lead-based solder, work in a well-ventilated area (science lab) and students must wash hands after use. References for additional safety measures are on next slide.

22. 22 Building the Robot – Parts and Instructions Verify the parts from the materials list in the Manual Limited spare parts can be obtained through your WIE representative READ THE ENTIRE MANUAL BEFORE BEGINNING TO BE CLEAR ON WHAT THE REQUIREMENTS ARE!

23. 23 Building the Robot - Rules The robot must be fabricated using parts provided in the kit To ensure a level playing field, NO deviations from the design of the Power Unit and Control Unit are permitted Substitutions are not allowed but additions are permitted. Gadgets to add personality are ok, but the basic mechanism of the robot cannot be changed

24. 24 If wheels or gears are used, they may NOT touch the table or be externally visible The robot body must be designed such that the team can fully expose all mechanism for inspection by the judges Building the Robot - Rules

25. 25 Building the Robot – Planning and Building the Body Have a theme for robot, robot covering and storage/travel container and team with team flag Be aware that the covering may affect the robot’s center of gravity Body covering must be removable! Beware of fabrics with fibers (for example, felt or fur) that can affect mechanism

26. 26 Building the Robot - Suggestions HINTS and RECOMMENDATIONS  Protect metal rods from bending or breaking; tape to side of box for protection  Use wooden match to mix epoxy – don’t get it on work surface  Use caution when drilling  Wooden rulers are easiest to use Measure twice, cut once!

27. 27 Building the Robot - Wood Block Suggestions for wood block and challenges of 3/32 hole and 3/16 angled hole for wiring:  Use team of 2: driller and spotter  Do short channels first  Take all measurements from one side  Read instructions, mark holes  Use extruding drill bit and ruler to line up holes  Sand tip of metal rod to get thru connecting holes

28. 28 Building the Robot - Wood Block  Insert rod in vise. Push wood down onto it  If too loose, epoxy the inside; clean off outside as it needs to be rigid  Angled holes: angle block in vise and drill straight  Use coat hanger to push thru hole

29. 29 Building the Robot – Mounting Motors To increase contact surface, make shallow channel for motor On 001 drawing, section marked “ up to 2” “ is not necessary for the robot body and can be removed Insert screws by hand

30. 30 Building the Robot - Use of Epoxy Mix on disposable surface After epoxy is applied, use clamps or rubber bands to hold parts in place until dry

31. 31 Building the Robot - Threaded Rods Use Dremel tool or metal saw to cut threaded rod, then file smooth

32. 32 Building the Robot – Jammed Mechanism If leg action jams:  Make sure the rods are straight  Top rod – shorten back stop or use controller to take smaller/shorter steps  If end stops moving, use one drop of superglue (liquid, not viscous) on threaded rod, then clean and reassemble. (Imperfections are uncorrectable!)

33. 33 Building the Robot - Control Units Use nail to indent holes on platform Adhere to hole sizes; hangs too loose if holes are too large

34. 34 Building the Robot - Painting and Assembling Parts Decoration of robot is expected, continue use of theme

35. 35 Building the Robot - Forming Bridge w/ Brass Fasteners.

36. 36 Building the Robot - Common Bus

37. 37 Building the Robot - The Wiring

38. 38 Building the Robot - Soldering Do and Don’ts - see soldering safety Some solder contains lead – wash hands after handling! Use lowest temperature on 25 watt iron Clean and heat larger elements first Solder onto element without blobs!

39. 39 Building the Robot – Walking and Troubleshooting Rotational Movement of Leg is: UP -> FORWARD -> DOWN -> BACK Hip is flexible, leg foot is not flexible Center of gravity shifts with movement Center of gravity is affected by cover Use tape, hairspray or rubber cement on skids for traction

40. 40 Building the Body – Walking and Troubleshooting Plan time to PRACTICE MOVING THE ROBOT! It is harder than it looks!

41. 41 Building the Robot – Storage/Travel Container Consider strong possibility of damage to the robot on the way to the Challenge! Storage/travel container is judged at oral presentation Continue theme for robot and team Container suggestion: wine box w/partitions
