octanis1-electronics's Issues
Assemble one EPS v1.0 prototype and ensure its correct functionality
Solder 2 boards of EPS for rover
Create timelapses/videos from stereo cam data
Make interactive graphs of ROS data
Prototype of new mechanical design
Solder 1 replacement board of mainboard
Check if rover EPS can turn off current sensors
Olimex boot-done state not correctly detected by EPS
possible reason: charge remains on shutdown_state_pin -> add pulldown could be a solution.
Trip to Grenoble
- charge laptops
- take SD card reader
- collect rover
- copy data from SD card while in grenoble
- intensively survey researchers
- return to CH with rover and data
Mount solar cells on rover and test battery charging time, shadowing, parallel wall supply connected
New mechanical design ideas
Replace L/C & Rsense to limit charge current to 2A on all EPS
.. wait for components
Proper cabling and connectors for electronic boards
- Solder polarized connector for all battery and solar cell inputs
- Use flat cables and DIN connectors for board-to-board or board-to-module connections, for easy plug-and-play
- Ensure rigidity (mechanical stability) of the connections and solder joints
- Label all cables
Design new EPS
- add Vbat output with circuit breaker
- add 0R resistors everywhere to cut enable pins from mcu
- add jumper between VCC and MCU supply
- replace BGA with "normal" component
- add a second power input (5V USB) in parallel to solar input for battery charging.
Deadline: June 12th (design)
June 30th fabrication of 3 running boards
Determine max. windspeed for rover experiment
Pre-shipping: IMPORTANT: remove solar charger LEDs of rover EPS board
to avoid damage when connected to wrong power supply
Test all PCB's in freezer
(just test survival during 48h, not operation)
transform laserscan (rosbag) into map
Solder 2 boards of Weather Monitor Board for rover /Nawel and Ana
