Contents
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
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
[LOTS OF THINGS HERE NEED UPDATING]
Need to recover what was removed from previous versions of this page.
Radio
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.

To Do
- Transition the I2C bus lines to the microcontroller
- Update Verilog for new balanced encoder signals (A+, A-, B+, B-)
- ( (A+) + (A-) == 0 ) should be true for no errors
- Complete all Unknown fields for the FPGA's SPI protocol in the above tables
Completed
- Finalized that the 2015 motor will use the current FPGA
- Xilinx Spartan-3E
