Embodiment Construction

[0025] Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing and embodiment:

[0026] Observing the process of the grebe running on the water surface, it can be found that when it treads on the water, its webbed feet provide a good contact area and provide enough reaction force for its running; while when it comes out of the water, the webbed feet can Shrinks under resistance to reduce water resistance. This way of foot deformation provides a strong guarantee for its ability to run on water.

[0027] see Figure 1 to Figure 8 As shown, the present embodiment is a dual-purpose biomimetic soft actuator, which includes two parts, the first driving module 1 and the second driving module 2 . When the actuator is in the grebe-like water running mode (as the end effector of the water running robot), the second drive module 2 plays the main driving role; when the actuator is in the fish-like swimming mode (as the water swimming r...

Abstract

The invention discloses a dual-purpose bionic soft actuator. The problem that an existing soft robot end actuator is single in function is solved. The dual-purpose bionic soft actuator comprises a first driving module and a second driving module, wherein the first driving module comprises pneumatic elements, a first variable stiffness unit and a first rack; the two pneumatic elements are symmetrically bonded to the two sides of the first variable stiffness unit and jointly fixed to the first rack; the second driving module comprises first air cylinders, a second rack, a third rack, a second variable stiffness unit, a second air cylinder, a telescopic paper folding structure, a fourth rack and a fifth rack; the second rack is hinged with the first rack; the two first air cylinders are hinged to the first rack and the second rack on the same side respectively; the two second variable stiffness units are installed between the first air cylinders and the second rack; the two third racks are symmetrically distributed on the left side and the right side of the second rack; the fourth rack is fixed to the outer sides of the third rack through the second air cylinder; and the telescopic paper folding structure is fixed between the third rack and the fourth rack.

Description

technical field [0001] The invention relates to the technical field of soft actuators, in particular to a dual-purpose bionic soft actuator. Background technique [0002] In recent years, soft robots that simulate biological preparation have better compliance and stronger operational adaptability, and have attracted extensive attention from researchers. [0003] Soft robots using water as the medium, such as soft fish robots and soft jellyfish robots, have emerged at the historic moment, especially soft fish robots have been extensively studied. Existing mollusc fish robots can well simulate the movement of fish, and are widely used in related fields such as environmental monitoring, military reconnaissance, and fishery detection. [0004] As for creatures that use water as their living medium, in addition to fish that live in water for a long time, there are also some animals that can run on the water surface, such as grebes. Grebes can use their feet to run on the water ...
