Problems solved by technology

[0005] In addition, Saad Kashem of Swinburne University of Technology and others designed a quadruped bionic robot. The feet adopt the flipper design of swimming birds. The soles of the feet have a driven structure and do not need servo control. Although the structure saves space, The lack of freedom control of the feet cannot imitate the movement and changes of biological flippers at different stages

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] The invention provides a bionic machine flipper mechanism, such as Figure 1~5 As shown, it includes a leg bracket 1, a steering gear 2, a steering wheel 3, a transmission flange 4 and opening and closing flippers.

[0025] The foot support 1 is fixedly connected with the steering gear 2, and the steering wheel 3 is fixed with the output shaft of the steering gear 2. The transmission flange 4 is fixed to the steering wheel 3.

[0026] The opening and closing flippers include active rod-shaped feet 6, passive rod-shaped feet 9, fixed rod-shaped feet 11, flexible membrane webs 22, fixing parts I12, fixing parts II16 and sliding parts 21.

[0027] The active rod-shaped foot bone 6 is connected with the transmission flange 4 with an internally threaded rod at the lower end through the screw rod I5, the end of the passive rod-shaped foot bone 9 is prov...

Abstract

The invention discloses a flipper mechanism of a bionic machine. The mechanism comprises a leg support, a steering engine, a transmission flange and a folding flipper. The steering engine is fixedly installed on the leg support. The steering engine drives the transmission flange to rotate on a horizontal plane such that the transmission flange drives the folding flipper to expand and fold within the horizontal plane. The flipper can expand and fold. Accordingly, the flipper is stimulated to push animals to move in water. Therefore, the mechanism is highly flexible.

Description

technical field [0001] The invention relates to the technical field of bionic robots, in particular to a bionic robot flipper mechanism. Background technique [0002] With the development of human society and the continuous advancement of science and technology, various resources on the earth such as oil, coal, and natural gas are continuously consumed along with human activities. At the same time, the scope of human activities continues to expand, thereby occupying and destroying the habitat of coastal organisms and polluting the coastal environment. In recent years, with the large-scale development of marine resources and the increasing emphasis on the coastal environment, various unmanned marine robots have been widely used in marine scientific investigation, marine engineering, marine resource protection, marine aquaculture and other fields. Most underwater robots use the propeller propulsion method, which has the disadvantages of low energy utilization rate, poor maneu...
