摘要： An omnidirectional ghost imaging system based on a mechanism of bio-inspired retina-like includes a projection system, a collimating lens, a spectroscope, a curved mirror, a bucket detector, a data acquisition card and an arithmetic system. According to the application, the logarithmic polar mapping characteristic of the bio-inspired retina-like structure is utilized to generate an annular pattern sequence of the bio-inspired retina-like, and the pattern sequence is utilized to modulate a light source. After being reflected by the target around the curved mirror, the light is projected onto the curved mirror and diffusely reflected. According to the reversible characteristics of the optical path, the light after diffuse reflection is reflected to the original light source by the half mirror and half lens, and the reflected light intensity with target information is received by the bucket detector.

摘要： Provided are a quadruped robot and a spine-leg-foot coupling driving method, relating to the technical field of bionic robots. The quadruped robot includes an active spine, and two trunks. The two trunks are a fore trunk and a hind trunk, respectively. The two trunks can pitch and can be telescopically arranged at both ends of the active spine in a front-rear direction. The active spine can drive the trunks to pitch, extend and retract. In accordance with the spine-leg-foot coupling driving method, the pitch and retraction state of the spine and the energy storage and release state of legs during the running of a quadruped are stimulated by controlling the swing state of a swing output member, the extension and retraction state of the trunk and the energy storage and release state of an elastic leg.

摘要： Disclosed are a protection equipment, system and method for the destruction of explosives. The protection equipment for the destruction of explosives includes four modules: an inner fence, an outer fence, an anti-leakage fence and a top cover. The modular equipment takes an overall nonmetal flexible composite structure, and the individual modules are light in weight and convenient to operate. It can be operated by two persons or a single person. A protective effect can be achieved during destruction of explosives by using the protection equipment, and even if the explosives explode during destruction, it will not cause injury to surrounding personnel. A protection system for explosive destruction based on the protection equipment can be used to destroy unexploded bomb or explosives under protective conditions, thereby achieving rapid emergency disposal without making contact with the explosives.
