Abstract

The patent of the present invention provides a composite spherical shell of a spherical robot. The spherical shell composite structure includes a rigid matrix shell and a flexible coating layer. The rigid matrix shell is a structural fiber-reinforced composite material, which is composed of reinforcing fibers and a thermosetting resin matrix. Honeycomb stiffeners are arranged on the inner surface of the rigid matrix shell. The stiffener material is thermosetting resin, which can be combined with the rigid matrix shell. Integrated thermoforming; flexible coating layer adopts copolymer elastomer material. The lightweight composite spherical shell has high specific strength, specific stiffness, rolling friction coefficient, impact energy dissipation coefficient and quick repair function. The spherical shell and the corresponding spherical robot are used as an open automatic control platform, and a variety of functional spherical robots can be developed on the basis of the spherical robot composite spherical shell.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a functional spherical hollow shell structure facing a spherical robot. Background technique

[0002] The spherical robot is a system that installs motion actuators, sensors, controllers, and energy devices in a spherical shell. It is an instrument platform for exploration in special environments. It has good environmental adaptability and is not easy to overturn. Environment, such as the survey of pipeline ditches, liquid and corrosive environment operations, as a military reconnaissance combat platform. Because this type of robot has good dynamic and static balance, and has good sealing performance, it can drive in unmanned, sandy, humid, and corrosive harsh environments, and has amphibious functions. It can be used in planetary exploration, environmental monitoring, national defense equipment, entertainment and other fields. Due to the particularity of the spherica...
