4results about How to "Improve biomimicry" patented technology

This invention belongs to the field of biomimetic robot technology, and specifically relates to a linkage-type shoulder motion mechanism. The technical solution is as follows: A linkage-type shoulder motion mechanism includes a torso fixation base, a shoulder fixation base fixed to the top of the torso fixation base, a shoulder structure rotatably connected to the shoulder fixation base, a forward tilting drive link rotatably connected to the shoulder structure, a forward tilting power source mounted on the torso fixation base, the outer ring of the output end of the forward tilting power source being rotatably connected to the forward tilting drive link, and the forward tilting power source being located on the rear side of the shoulder structure; a shoulder shrug power source mounted on the forward tilting drive link, the outer ring of the output end of the shoulder shrug power source being rotatably connected to a shoulder shrug drive link, and the other end of the shoulder shrug drive link being rotatably connected to the side of the torso fixation base. This invention provides a linkage-type shoulder motion mechanism capable of realizing forward tilting and up-and-down shoulder shrugs.

The invention discloses a constant-temperature cyclic heating and efficient stir-frying integrated cooker structure, which aims to solve the problems of non-uniform heating and single stir-frying action of the existing cooker, and comprises a machine table, a stir-frying pan mounted in a groove of the machine table, and a thermal insulation layer covering the outer part of the bottom end of the stir-frying pan and forming a hot air channel with the outer wall of the stir-frying pan. A heating bin is arranged in the machine table, an electric heating plate is arranged in the heating bin, the electric heating plate and the hot air channel form a closed circulating air channel through an air inlet pipe and an air outlet pipe, and a stir-frying assembly is arranged over the stir-frying pan and comprises an elastic rubber column driven by a push rod motor to ascend and descend and driven by a rotating motor to rotate and a stir-frying frame fixed to the tail end of the elastic rubber column. Uniform constant-temperature heating is achieved through closed hot air circulation, meanwhile, the stir-frying frame which can be lifted and rotated and has the elastic tail end is used for simulating complex stir-frying actions, closed-loop cooperative control over the heating and stir-frying processes is achieved in combination with the temperature sensor and the controller, and the cooking uniformity, the finished dish quality and the automation degree are effectively improved.

The present application belongs to the technical field of bionic robot, and particularly relates to a chain belt type leg action mechanism. The technical scheme is as follows: a chain belt type leg action mechanism, comprising left and right swing power sources, the output end of the left and right swing power sources being connected with a waist fixing end, a supporting connecting rod being rotatably connected to the shell of the left and right swing power sources, further comprising a thigh base body, the other end of the supporting connecting rod being fixed with the thigh base body, a front and back swing power source being installed on the thigh base body, the output end of the front and back swing power source being provided with an output fixing disc, a driving fixing disc being fixed to the shell of the left and right swing power sources, the output fixing disc and the driving fixing disc being connected through a steel belt transmission. The chain belt type leg action mechanism can swing forward and backward, swing left and right or compound motion.

The invention belongs to the technical field of organ chips and biological manufacturing, and relates to a vascularized multi-tissue interaction organ chip based on a phase change sacrificial structure and a construction method and application thereof. According to the invention, collaborative construction of multiple tissue chambers and a blood vessel-parenchymal tissue biological interface is realized through a continuous phase change process of the sacrificial hydrogel material; according to the organ chip disclosed by the invention, an extra diaphragm or complex processing is not needed, the continuity and the bionic property of a multi-tissue interaction interface are maintained, the simulation of signal exchange and a pathological process among multiple tissues in a body is facilitated, and the organ chip has higher bionic property and applicability in applications such as complex physiological interaction modeling, drug evaluation and disease mechanism research.
