  1. H193 Project Lecture 30 Winter Quarter

  2. ENG H193 Administrative Issues • Teams should be established March 26th or so (Watch your email over spring break) • Each team member must purchase a coupon • All four (or three) coupons must be purchased before the team gets their starter kit • The cost of the course materials is $75 per team member. Please bring cash or check to purchase the coupons (No Buck-ID, no charge cards) • Coupons will be sold in the office (HI 244) on Monday thru Wednesday the first week of class Winter Quarter

  3. ENG H193 Robot "Starter" Kit • One completely functional Handy Board with charger/interface box, wall adapter, serial cable, link cable, and simple documentation • Basic set of sensors (CdS cell, optosensor, microswitches, IR receiver, encoder) plus some miscellaneous stuff • One kit of basic hand tools • One copy of "Robotic Explorations" by Fred Martin (the guy who designed the Handy Board) • Teams get $150 budget in Company Store Winter Quarter

  4. Reference Text Supplied Winter Quarter

  5. Typical Problems from Previous Years • Building a rigid chassis • Mounting a motor on the chassis • Connecting the motors to the drive wheel, sprocket, etc. • Getting the robot to drive straight • Reducing friction • Not starting soon enough ! Winter Quarter

  6. Typical Problems from Previous Years • Mounting sensors – avoid hot glue and duct tape • Mounting minimum no. of sensors to perform functions • Spaghetti wiring – Label wiring for each component (allows easy reinstallation of all wiring when you have to change Handy Board !) • Pick a color-coded wiring scheme and stick to it • Protecting the power trace on the Handy Board – The edge of the board is the +5V supply for the processor chip Winter Quarter

  7. The Handy Board Winter Quarter

  8. Typical Problems from Previous Years • Not making good solder joints • Not having enough sensors wired as spares • Not taking care of your batteries • "Zap" charge will zap (i.e., kill) your battery • First battery replaced at nominal fee • Second battery replaced at cost (about $20) • Not starting soon enough ! Winter Quarter

  9. Typical Problems from Previous Years Winter Quarter

  10. Typical Programming Pitfalls • Too much code – exceed memory of Handy Board • Failing to use global variables • Scarcity of comments in code (comments don’t take any memory space) • Improper use of functions • Inappropriate timing to check sensors • Not using modular approach to building code, not checking modules often • Suggestion -- Write a general "check sensor" routine and run it periodically • Not starting soon enough ! Winter Quarter

  11. Potential Team Problem Areas • Making decisions that everyone supports • How to make decisions • Making work assignments • What happens when an individual is having trouble completing assigned work • Making a project schedule and keeping it updated (this will be a living document and requires weekly/daily change) • What to do if someone doesn’t come to meetings • HAVING ALTERNATIVE PLANS !!!!!! AND KNOWING WHEN TO GO TO THEM !!!!!! Winter Quarter

  12. Pursue Achievable Goals Winter Quarter

  13. Take Calculated Risks Winter Quarter

  14. Keeping Up with Daily Work • Sharing project notebook, updating, team meeting agenda, and team meeting notes assignments • Document meetings and decisions made with rationale behind them • Checking the schedule • Keeping others up to date on your progress Winter Quarter

  15. The 2003 FEH Robot Competition • Final Competition: May 29, 2003 from 3:30 to 5:30 • Admission is free – friends and parents welcome • There will be some early rounds conducted during the middle of the day starting at about 12 noon • Competition style will likely include three rounds of match play followed by a single-elimination tournament -- This guarantees each team 4 opportunities to run on competition day Winter Quarter

  16. The Venue – French Field House Winter Quarter

  17. The Final Report Winter Quarter

  18. Celebrating Success – End of Year Picnic Winter Quarter
