  • Crawler Robot

    Features:
    - Size & Weight: It is compact (800x500 mm) and light enough (~24 kg) to be carried by one person.
    - Tough Mobility: It drives over rubble, mud, and slopes in any weather, and is fully waterproof.
    - Clear Vision: It uses built-in lights and a 360° rotating camera to stream real-time video directly to a tablet.
    - Versatile: It can carry up to 15 kg of extra sensors or tools and easily switches between wired or wireless control.

  • Scouring Investigation Camera

    Features:
    - Prompt check of scouring conditions (primary screening)
    - If abnormalities are detected, follow-up by ASV/Boat drones
