  1. sp t Critical Design Review

  2. sp t Team Saurabh Gupta PCB, Power Bryan Lavin-Parmenter Software Architecture Brandon Pon PCB, SoM Neil O’Bryan Peripherals

  3. sp t Vision To build a device that will allow astronauts to path- fi nd on unknown terrains in space

  4. sp t Design Assumptions No trails, roads, or landmarks for way- fi nding Localization is available (i.e. GPS) Astronauts are walking, not traversing via rover Astronauts are partially physically encumbered Astronauts are not just navigating, but are multi-tasking while navigating terrain

  5. sp t Design System Architecture Wireless Antenna Home Base Direct User Display Tactile Control Power GPS with RTK RTK Wireless Dual-lead 40-pin Direct SPI Communication Direct I2C SPI Antenna IMU SoM Transceiver I2C I2C SPI RS-232 Haptic Motor Range fi nder Camera Biosensor

  7. sp t Design Enclosure 20 2.6 10 7.6 12.1

  8. sp t Design Software Architecture Add new data to local Home base relays Perform peripheral- storage, remove old information speci fi c function data other thread multiple threads Home base fi nd and Peripheral GPS Relay to home base Boot up sanity check monitoring to get RTK data display input Get coordinates and Determine if object relay to home base nearby Alert user

  9. sp t Testing Software Methodology: Test-Driven Development TDD: Testing before implementation Write code tests that fail before writing new implementation logic 2P Review: All code must be reviewed and critiqued by another team member

  10. sp t Flow In Range of POI while marking enter POI range start the mark leave POI range fi nish or cancel the mark In Range Marking POI fi nish the mark of POI start the mark enter POI range leave POI range, cancel cancel the mark alert Idle
