About Water Surface Drones (USV/ASV): https://hmrc.co.jp/usv/ Description: Explains what water surface drones (USV/ASV) are. USV = Unmanned Surface Vehicle, ASV = Autonomous Surface Vessel. Generally refers to unmanned surface robots under 20 tons operating in seas, lakes, rivers, and dams. Covers vessel types (portable, ultra-compact, high-speed, traditional boat/pontoon, catamaran, barge, amphibious), remote control methods (RC/FPV controller 2.4GHz/300m, browser-based, wired tether 100–1000m, VPN), and automation/autonomous navigation.
