Section1: read through URC 2025 and define the competition requirement

  • Build remote operated

  • missions

    • Science Mission (20 - 30 mins)

      • collect sampleHigh Priority

        • (2 sites within 500 meters of the command station)

      • evaluate the sampleMedium priority

        • need evidence of (water flow, mineral, soil structure)Not urgent requirement

        • show overview picture and detailed picture (gimbal?) Medium priority

        • GPS record of the location taken at the site High Priority

        • camera to identify the trace of water

        • analyzed by rover onsite

      • store the sampleHigh Priority

        • Sample needs to be 10cm deeper in the ground

        • Soil moisture testing and temperature testing

        • at least 5 gram

        • need to be stored properly

      • Need own system, not share system

    • delivery mission (30 ~ 60 min) (2 stages)

      • 2 stage == 2 tasks given

        • Follow a marked path, require precise movementHigh Priority

        • open the box of a hinged lock

        • pick up, carry and deliver to another location max 5kg

          • size: 7.5cm wide handle

          • max object size 40cm x 40cm x 40cm

        • visual search of an object with 20 meters of provided coordinates

        • Cart for carrying multiple objective (optional)

        • Have to work with GNSS

        • operate BVLOS

    • equipment service mission (30 min)

      • The rover up to 2.5km flat to reach the site

      • 1.5 meters high from the ground

      • Pick up the container to the rocket

        • 10 cm long, not more than 5cm diameter for the handle

        • 5 kg max

      • Open the drawer, insert the soil sample, and close the drawer

      • Tighten a screw (5/16 inch)

        • decide not to pick up the screw drawer

      • Type the keyboard using the rover

        • type correct

        • four positions to direct an antenna, to observe a gauge

      • pick up the USB stick and insert a USB A stick

      • Push buttons, flip switches and turn knobs

    • autonomy navigation mission (30 - 60 min)

      • Accumulated distance < 2km

      • Traverse GNSS required location

        • two location with GNSS coordinate (no visual markers)

        • stop within three meter

      • Three posted marked with AR tags

        • GNSS coordinate within a range (5 ~ 20 meter)

        • Stop within two meters of the post

        • Three-sided visual marker 20 x 20 cm phases

        • 0.5 to 1.5 meter above ground

      • Traverse to two objects on the ground

        • GNSS coordinate within 10 meter

        • autonomous detect the object required

        • the second object may have obstacles that require object avoidance
