Description

Technical Field

[0001] This invention relates to the field of biomimetic robot technology, specifically to a soft robot adapted to various motion environments and its intermediate connection module. Background Technology

[0002] In recent years, the field of soft robotics has achieved remarkable development, as soft and flexible materials have the potential to endow robots with new capabilities, unprecedented adaptability, and inherently safe interaction with humans and the environment. The deformability of soft robots allows them to surpass traditional rigid robots' attempts to simulate continuous biological motion and promotes stress distribution over large areas, preventing mechanical damage from accidental impacts. Biomimetic soft robots can cope with complex environments and achieve remote operation and detection through integrated vision and control. Particularly useful when the working environment poses a risk to humans, biomimetic soft robots with mobility can replace humans in environmental detection and inspection, and even perform tasks in their place.

[0003] While biomimetic soft robots offer significant advantages in flexibility and environmental adaptability, they also face several challenges, such as how to adapt rigid connectors to flexible bodies, how to design connectors to facilitate robot configuration changes, and how to plan motion to adapt to the environment. Therefore, this design is based on a modular design philosophy. The key to modular design lies in the design of the connecting modules between them to ensure interoperability and reliability. Motion is primarily achieved through structural design and the connections between multiple modules, improving the collaborative efficiency and reliability of the modular soft robot. Connecting components for soft robots typically employ robust materials and designs to provide high strength and stability, while also facilitating installation and disassembly. The design advantages of connecting components lie in their strength and stability, disassembly and maintainability, as well as adaptability and compatibility. This makes connecting components a crucial component in many modular soft systems, ensuring the robot's operational stability.

[0004] This design is a modular soft robot, where each module can independently generate worm-like movements. Connectors allow for various robot configurations and more complex movements, such as movement on sand, slopes, and underwater. This design enables the robot system to add or remove modules as needed for the task, significantly improving the flexibility and adaptability of the soft robot. Summary of the Invention

[0040] Specific implementation method one: Combining Figures 7 to 12 This embodiment describes an intermediate connection module for a soft robot adaptable to various motion environments, comprising a fixed module and a bidirectional sliding module 12. The bidirectional sliding module 12 is disposed on the outer end face of the fixed module and is linearly slidably connected to the outer end face of the fixed module.

[0041] Specific Implementation Method Two: Combining Figures 7 to 12 This embodiment describes a fixing module comprising an outer frame 11, a pressing module 13, an L-shaped bracket 14, and a front cover 15. The outer frame 11 is a rectangular frame. The pressing module 13 is vertically inserted into the front side wall of the outer frame 11 at its center. A pressing handle 131 is provided at the outer end of the pressing module 13. An inverted U-shaped bracket 132 is fixedly connected to the inner end of the pressing module 13.

The vertical section of the L-shaped bracket 14 is disposed within the outer frame. The middle part of the outer frame 11 is located inside the inverted U-shaped bracket 132. The horizontal section of the L-shaped bracket 14 is located at the rear of the lower end of the outer frame 11. The lower end face of the rear sidewall of the inverted U-shaped bracket 132 is slidably connected to the upper end face of the horizontal section of the L-shaped bracket 14. A first spring 16 is provided between the middle of the vertical section of the L-shaped bracket 14 and the middle of the front sidewall of the inverted U-shaped bracket 132. Two second springs 17 are arranged side by side between the rear sidewall of the inverted U-shaped bracket 132 and the rear sidewall of the outer frame 11. The front sealing layer 15 is fixed to the outer end face of the outer frame 11. The undisclosed technical features in this embodiment are the same as those in specific embodiment one.

[0042] The outer frame 11 is rectangular in shape and made of rigid plastic. The outer frame 11 is used to support the intermediate connecting module.

[0043] By applying a downward force to the pressing module 13, the first spring 16 and the two second springs 17 are compressed under the action of the pressing module 13, thereby increasing the gap between the vertical section of the L-shaped bracket 14 and the rear side wall of the inverted U-shaped bracket 132, so as to realize the separation between the bidirectional sliding module 12 and the fixed module, and complete the modular assembly and disassembly.

[0044] Specific implementation method three: Combining Figures 7 to 12 In this embodiment, a first upper positioning protrusion 134 is vertically fixed to the middle of the front sidewall of the inverted U-shaped bracket 132, and a first lower positioning protrusion 142 is vertically fixed to the middle of the vertical section of the L-shaped bracket 14.

The inner end face of the front sealing layer 15 has two diagonally opposite cylindrical inserts 151, each inserted into a cylindrical fixing hole. The undisclosed technical features in this embodiment are the same as in specific embodiment two.

[0047] This design achieves effective fixation between the front sealing layer 15 and the outer frame 11.

[0048] Specific Implementation Method Five: Combining Figures 7 to 12 This embodiment describes a bidirectional sliding module 12 comprising a slot plate 121 and a connecting plate 122. The slot plate 121 is disposed on the outer end face of the front sealing layer 15, and the connecting plate 122 is disposed within the outer frame 11. A slot 123 is formed on the inner end face of the slot plate 121. The outer end of the connecting plate 122 is inserted into and slidably connected to the slot 123. The upper end face of the connecting plate 122 is inserted into and connected to the vertical section of the L-shaped bracket 14, and the lower end face of the connecting plate 122 is inserted into and connected to the rear side wall of the inverted U-shaped bracket 132.

[0049] The connecting plate 122 is disposed between the rear side wall of the inverted U-shaped bracket 132 and the vertical section of the L-shaped bracket 14, and is clamped by the rear side wall of the inverted U-shaped bracket 132 and the vertical section of the L-shaped bracket 14 under the elastic force of the first spring 16 and the second spring 17. The connecting plate 122 is slidably connected to the slot 123, so that relative movement can occur between the two, thereby realizing the relative movement between the bidirectional sliding module 12 and the fixed module.

[0050] Specific Implementation Method Six: Combination Figures 7 to 12 This embodiment describes a slot 123 comprising a transverse groove and a longitudinal groove, which are perpendicularly intersecting at their midpoints. Undisclosed technical features in this embodiment are the same as in specific embodiment five.

[0051] This design allows for a 90° rotation connection between the front and rear sides of the soft robot, with the dovetail slider 126 positioned within a transverse or longitudinal groove as needed.

[0052] Specific implementation method seven: Combination Figures 7 to 12 In this embodiment, the outer end of the connecting plate 122 is provided with a dovetail slider 126. Both the transverse and longitudinal sliding grooves are dovetail grooves, and the dovetail slider 126 is slidably connected to the transverse or longitudinal sliding groove.

[0054] This design allows the connecting plate 122 to slide between the rear side wall of the inverted U-shaped bracket 132 and the vertical section of the L-shaped bracket 14 for gap opening and closing adjustment.

[0055] Specific Implementation Method Nine: Combining Figures 1 to 12 This embodiment describes a soft robot adaptable to various motion environments, comprising an intermediate connecting module 1 and four soft modules 2. Two soft modules 2 are connected to each end of the intermediate connecting module 1, with the two soft modules 2 fixedly connected vertically and facing away from each other.

In order to enhance the stability of the fixing module, multiple first through grooves 111 are evenly distributed along the length direction on the upper and lower side walls of the outer frame 11. During injection, glue is also injected into the first through grooves 111 to enhance the bonding performance.

[0060] The bidirectional sliding module 12 is disposed in a trapezoidal cavity at one end of the connecting module 1 in the middle of the connecting end, and is fixed in a separate trapezoidal cavity by injection of glue. In order to enhance the stability of the bidirectional sliding module 12, multiple second through grooves 124 are evenly distributed along the length direction between the upper and lower end faces and between the front and rear end faces of the slot plate 121. A rectangular groove is provided on the outer end face of the slot plate 121. Glue is also injected into the second through grooves 124 and the rectangular groove during glue injection to enhance the bonding performance.

Air is pumped into or out of eight chambers through air inlet and outlet ports 26, achieving deformation of the strain layer 24. Different motion modes are generated when different internal cavities are inflated or deflated. By pressing the push module 13 in the intermediate connecting module 1, the fixed module and the bidirectional sliding module 12 can be quickly connected and separated, thereby achieving integrated connection of the soft robot. This facilitates operation, provides strong reconfigurability, and the robust mechanical structure is suitable for multi-mode motion switching of modular soft robots, greatly increasing flexibility.
