The unmanned ship (unmanned surface boat) is another section of high-tech frontier research that has been focused on after the boom in drones. Both the unmanned boat and the ship model can run on the surface under the control of the remote control. In many cases, the appearance is very similar. What is the difference between the unmanned ship and the ship model we are more familiar with? Unmanned ships can be divided into military and civilian parts. Military unmanned ships can be carried by aircraft or large ships, and can be deployed after reaching the scheduled location, or used near the base to protect themselves and attack the enemy. Civil unmanned vessels are mainly used in environmental protection, hydrology, surveying and mapping. The ship model focuses on viewing, collecting, and competition. Therefore, we rarely discuss the scope of its application. Unmanned boat/ship model The ship model has low requirements for the material of the hull. The wood material can be selected from epoxy resin, glass steel, PVC or ABS board and alloy. The unmanned ship is considered to be equipped with a functional unit, and the material needs to consider various factors such as water repellency, impact resistance, microwave penetration, etc., and now more use of FRP, Kevlar composite materials. As a leading domestic water robot system service provider, Kewei Intelligent has adopted a new carbon fiber + Kevlar composite material. This composite material makes up for the shortcomings of traditional materials that are difficult to balance strength and toughness at the same time. It is also satisfactory in terms of magnetics and insulation. Kevlar / carbon fiber material The engine is the "heart" of the ship model. In the nautical model competition, a ship with a cool shape wants to win the championship is inseparable from the excellent propulsion system. The boat model engine can be used with small aircraft models, mostly single-cylinder, two-stroke gasoline engines. The unmanned ship propulsion system is divided into a pump-jet propeller, a pod-type propeller (POD propeller), a ducted propeller water-jet propulsion system, and a diesel and electric power starting system, which are equipped according to driving requirements. Airplane models usually require a remote control to manually control their trajectory. The unmanned ship passes the precision satellite positioning system, and the built-in control system can now realize the functions of autonomous navigation, automatic barriers, route presets, etc., and the operation is more intelligent and humanized. Navigation software interface for mobile/tablet applications The model is therefore limited by factors such as the material, size, and power system of the hull. The core of the unmanned ship is the variety of functional units it carries. According to the demand, the unmanned ship can be equipped with sonar, depth sounder, water quality monitoring equipment, GNSS, remote control machine gun, anti-submarine equipment, etc. to achieve efficient completion of various types of waterborne tasks. The C100P new acoustic measurement surface robot developed by Kewei Intelligent is equipped with single beam depth sounder, small side sweep sonar, ADPC and other mapping instruments for hydrological flow information collection and underwater topography measurement. Summary: The ship model manufacturing stays in the crafts and model stage, and some of the competition ship models are equipped with a launching system for the pursuit of speed. The unmanned ship is an intelligent product that integrates and manufactures a variety of advanced technologies to meet the various needs of military or environmental mapping. As the most advanced system service provider in the field of unmanned ships in China, Kewei Intelligent has launched a number of excellent performance products. Its products use new composite materials, built-in self-developed propulsion system, control system, and can carry a variety of professional equipment. It can meet the professional needs of users in different industries. A new multi-functional surface robot designed and developed by Kewei Intelligent
