Phase I: Techanical Analysis

The first stage of the 2014-2015 RoboCup redesign involves brainstorming potential upgrades by researching new technologies/resources since the last revision. A parallel analysis of current robot bugs and potential enhancements is also done at this time. Outlined below is a listing of resources that the team used in it's brainstorming stage.

Competition 2014

Phase II: Design

Layout

Max PCB Dimensions

To Do

  • Determine location and placement for dribbler motor header
  • Determine optimal placement direction for drive motor's phase connections (motor board)
  • Add connection header for ball sensor to control board
  • Add wires among connections in CAD assembly files
  • Test motor wire modifications before working on the entire batch of motors
  • Determine kicker connections and integration
