Automatic Shifting Bicycle Team Tim Slevin-Vegdahl (Fall Team Lead) Joan Javier (Spring Team Lead) Brendan Figuly Cyrus Medrano Advisor Dr. Robert Albright, Dr. Peter Osterberg, Dr. Timothy Doughty Industry Representative Mr Walter Harrison University of Portland School of Engineering

Introduction What- Auto shifting bicycle Who- New cyclists or those with limited hand dexterity University of Portland School of Engineering

Scorecard Bike testing, maintenance, and measuring - Assemble three gears cassette on the rear hub - Testing motor torque Functional Specification v1.0 approved Submitted initial MOSIS .edf file Define all MOSIS inputs and outputs - 4 inputs and 6 outputs University of Portland School of Engineering

Plans Complete MOSIS chip design and submit .edf file to Dr. Osterberg by Nov. 22 Complete magnetic sensor design Order batteries and motor compatible for project. - Inexpensive, feasible motor Submit Design Document v0.9 and v0.95 University of Portland School of Engineering

Milestones Status Description Original Target Previous Present Complete Project Approval 3 Sept 2010 Acquire a Bike 16 Sept 2010 Complete Function Specification v0.001 24 Sept 2010 29 Sept 2010 Timing Logic and Counter Functional in B2Logic.blt 11 Oct 2010 Missed Order a Battery and Motor that is Compatible for the Project 15 Oct 2010 Functional Specification v1.0 Approved Comparator Functional in B2Logic.blt 31 Oct 2010 Complete Design for Magnetic Sensor Complete Design Document v0.9 and v0.95 5 Nov 2010 Submit Initial MOSIS Chip.edf File 12 Nov 2010 Complete Second Draft of Design Document 19 Nov 2010 Submit Final MOSIS.edf File Design 22 Nov 2010 Design Document v1.0 Approved 24 Nov 2010 Toward the end of this file are two slides titled “Understanding Milestone Dates” and “Color Coding Milestones” respectively. Review these carefully before completing this slide. University of Portland School of Engineering

Concerns/Issues Motor Interface Circuit Proper Documentation - Communication between circuit and motor Proper Documentation - Minutes and Journal University of Portland School of Engineering

Conclusion Project Introduction Scorecard Future Plans - Bicycle Maintenance and torque measurements - Functional Specification v. 1.0 approved Future Plans - Need to order parts Status on Milestones - MOSIS chip design is on track for Nov. 22 deadline Concerns/Issues University of Portland School of Engineering
