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
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
Reference Text Supplied Winter Quarter
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
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
The Handy Board Winter Quarter
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
Typical Problems from Previous Years Winter Quarter
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
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
Pursue Achievable Goals Winter Quarter
Take Calculated Risks Winter Quarter
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
