Objective: Build two "robots" that will primarily take latitude/longitude associated photos using a RasPi per "robot".

"Context": sail on a residency inside a commercial cargo ship

Requirements:

• Robot 1:
  • Take a picture every 10 minutes.
  • Record GPS' lat/lon with image
  • Synchronize RasPi system time with GPS
  • Runs on battery, must be recharged daily.

• Robot 2:
  • Take a picture every 10 minutes.
  • Record GPS' lat/lon with image
  • Synchronize RasPi system time with GPS
  • RasPi connects to any available open WiFi network and will upload all new images. <ref>"JoinOpenWifi Tool"</ref>
  • Runs on battery, must be recharged daily.

Working Principle:

• The robots are powered using a phone battery pack that is charged via a standard USB charger.
• Both RasPis will be in the "box" with only the two USB power cables and possibly the WiFi antenna sticking out.
• GPS module must be on the exterior of the glass mirror box (faraday).
• Software makes sure that images are taken, GPS time is synchronised with OS time and a watchdog process reboots (or restarts the process) if something unexpected happens.
• Remote (while physically next to the box) SSH access to the RasPis can be provided using standard Ethernet cables. WiFi is not possible as this will be used for the "autoupload" mechanism and better left alone for this purpose.
