Introduction

Introduction

  • Design a device that will automatically shift the gears of a bicycle

  • Benefits new bicyclist and people who do not know how to properly shift gears on a bicycle

Scorecard

Scorecard

  • Mount magnetic sensor onto bicycle after verifying functionality

  • Debug Macro Model so we can compile and burn our CPLD

  • Complete actuator to be functional (get motor running off CPLD)

Concerns issues

Concerns/Issues

  • MOSIS chip will not be here for Founders Day and the current backup does not function to the specs we need. We will need to make aPlan C controller.

  • Our schedule will be behind on the actuation because we need a driver for the stepper motor.
