Revision as of 22:28, 6 December 2014

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 [FINISH UPLOADING IMAGES TO THIS PAGE. MANY ARE MISSING]

Phase II: Design

Controlling Unit

To Do

Completed

  • Obtain mbeds for robot use

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

Completed

  • Update hall connection header to right angled one
  • Add pin locations to all connection housings in CAD part files
  • Update the 14-pin connection header (female) for the control-to-motor board connection
  • Finalize method for adjusting motor wire lengths when motors arrive
  • Determine placement of battery location

Radio

CC1101 C++ library

Current protocol [LINK TO BE CREATED & UPDATED]

To Do

  • Determine optimal secondary frequency for base station updates
  • Test methods using breakout boards and compare data rates
  • Successfully communicate using two (2) NRF24L01+ transceivers and two (2) mbeds
  • Research and determine best steps for structuring radio protocol with primary and seconday frequencies

Completed

  • Successfully communicate using two (2) CC1101 transceivers and two (2) mbeds
  • Obtain breakout boards for CC1101 and NRF24L01+

FPGA

A few major change to the FPGA's Verilog code must be made for the 2015 redesign. This means documentation mean be produced/located for how the FPGA currently communicates on the SPI bus and append documentation for new protocol.
