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.
Phase II: Design
Layout
To Do
- Determine location and placement for dribbler motor header
- Update hall connection header to right angled one
- Determine optimal placemnt direction for drive motor phase connections (motor board)
- Add connection header for ball sensor to control board
- Update the 14-pin connection header (female) for the control-to-motor board connection
- Add pin locations to all connection housings in CAD part files
- Add wires among connections in CAD assembly files
- Finalize method for adjusting motor wire lengths when motors arrive
- Determine kicker connections and integration
- Determine placement of battery location
Radio
To Do
- Determine optimal secondary frequency for base station updates
- Order breakout boards for radio transceivers
- Test methods using breakout boards and compare data rates
FPGA
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
Motors
To Do
- Order motor controller boards
- Test different circuits and document data result set to wiki
Motion Sensing
To Do
- Create breakout board for MPU-9250 and place on GitHub repo (robocup-pcb)
- ?Update EAGLE part libraries too
Error Detection
To Do
- Create breakout board for MCP23017 and place on GitHub repo (robocup-pcb)
- ?Update EAGLE part libraries too
