Description

Technical Field

[0001] This application relates to the field of robotics technology, and in particular to a sliding and climbing composite robot. Background Technology

[0002] For a long time, human activities in icy and snowy environments have been limited due to factors such as terrain and climate. In recent years, with technological advancements, many countries have explored and developed environments such as icy mountains and polar glaciers, and intelligent devices designed for these environments are expected to receive considerable attention. In 2009, Yoneyama et al. at Kanazawa University in Japan conducted research on simulated turns using skiing robots, verifying the effectiveness of the extension, adduction, and flexion / extension movements in skiing. From 2008 to 2013, Zalaypah's team in Slovenia designed a three-degree-of-freedom skiing robot, incorporating coordinated torso movements to aid stability control during turns. From 2012 to 2016, Chris Iverach-Brereton et al. in Canada presented a research scheme for a skiing robot based on a commercial humanoid robot. In 2018, Kookmin University in South Korea designed the RoK-2 upright skiing robot and developed a deep learning algorithm for quickly identifying skiing obstacles. In the same year, Saga et al. in Japan designed a passive skiing robot to study the influence of ski shape and robot center of gravity on skiing turns. Domestically, Chinese patent CN114310963A disclosed a six-legged skiing robot developed by Shanghai Jiao Tong University. This robot uses four legs to control two skis, while the other two legs simulate ski pole application. Because humans use a large number of joints when skiing, most humanoid skiing robots suffer from high degrees of freedom and complex structures. Furthermore, research on braking mechanisms and composite designs is limited.

The first gear G4 and the second gear G3 of the left shoulder frame gear set mesh and transmit power. The second gear G3 of the left shoulder frame gear set is fixedly connected to the rotating central shaft 8. When the second motor M5 drives the first gear G4 of the left shoulder frame gear set to rotate, the second gear G3 of the left shoulder frame gear set and the rotating central shaft 8 will also rotate synchronously. Two worm gears 15 are fixed on the rotating central shaft 8, which transmit power to the worm gear 14 on the worm gear connecting rod 5. When the rotating central shaft 8 rotates, the worm gear connecting rod 5 can swing up and down through the worm gear transmission, thereby driving the skis 6 to move up and down horizontally, thus lowering and raising the body or assisting in crawling movements. The first motor M4 of the left shoulder frame drives the first gear G1 of the left shoulder frame to rotate. The first gear G1 of the left shoulder frame meshes with the left swing bracket gear G2 on the left swing bracket 4. When the first motor M4 of the left shoulder frame drives the first gear G1 of the left shoulder frame to rotate, the left swing bracket gear G2 drives the swing bracket 4 to swing, thereby causing the entire ski to swing at an angle.

[0161] In this embodiment, the left shoulder frame assembly and the right shoulder frame assembly of this application have the same structure, and the left sliding leg assembly and the right sliding leg assembly of this application have the same structure and the same working principle. Therefore, they will not be described in detail here.

[0162] like Figure 3 As shown, the left drive shaft 3 is fixedly connected to the left gear G7, and the right drive shaft 12 is fixedly connected to the left gear G7. The first motor M3 drives the first motor gear G5 to rotate. The first motor gear G5 meshes with the left gear G7, and the left gear G7 meshes with the right gear G6. When the first motor M3 drives the first motor gear G5 to rotate, the first motor gear G5 drives the left gear G7 to rotate, and the left gear G7 in turn drives the right gear G6 to rotate, thereby causing the left drive shaft 3 and the right drive shaft 12 to swing.

[0163] like Figure 4 As shown, the left drive shaft 3 and the right drive shaft 12 are connected to the left and right sides of the body through a guide rail slider mechanism. When the left drive shaft 3 and the right drive shaft 12 rotate, the slider 3-3 is connected to the connecting rod and slides on the left shoulder guide rail 3-4, driving the left and right sides of the body to expand relative to the middle body, so that the skis on both sides unfold in a V-shape, thereby realizing the V-shape or V-shape braking action in skiing.

[0164] like Figure 5 As shown, the left drive shaft 3 is fixedly connected to the connecting rod sleeve 3-2, and the slider bolt 3-1 is bolted to the slider 3-3. The left drive shaft 3 is rotatably connected to the slider bolt 3-1. The left drive shaft 3 connecting rod can rotate about the slider bolt 3-1 as the axis, and the slider 3-3 can slide on the left shoulder guide rail 3-4.

[0165] See Figure 7 The skiing robot has two skiing turning postures, which are the same as the turning principle of skiing on two skis. The robot turns by shifting its own center of gravity. Turning posture 1 has a larger turning radius than turning posture 2. Turning posture 2 has more contact with the ground and the turning effect is more stable.

[0166] In this embodiment, the robot has two movement modes: gliding and crawling. The gliding mode mimics the principle of human skiing on two skis, turning by shifting the robot's center of gravity, and adding tailfoot propulsion to simulate ski poles. In the crawling mode, the robot can open its left and right sides, with the middle part of the body touching the ground, and swing the sides up and down to crawl on the ground or overcome obstacles.

[0167] like Figure 8 As shown, the skiing robot has a ground crawling mode. In crawling mode, the robot can first open the left and right sides of the body until the middle body touches the ground, then swing forward and lift the skis on both sides, press down the skis on both sides to lift the middle body, and then the worm gear mechanism pushes the middle body to move forward in the air. Then, this gait is repeated to realize the skiing robot's crawling.

[0168] As shown in Figure 9, the skiing robot can use its tail foot 1 for propulsion in skiing mode. The motor M1 drives the tail foot mechanism 1 to rotate, and the toe 1-1 contacts the ground, providing forward propulsion for the robot while skiing.

[0169] In this embodiment, the left and right sliding leg components have degrees of freedom in terms of height and swing angle; the height extension and retraction of the sliding legs are achieved through a double worm gear transmission; the second gear G3 of the left shoulder frame gear set is tightly fitted with the two worms on the rotating central shaft 8. When the first gear G4 of the left shoulder frame gear set rotates, driving the second gear G3 of the left shoulder frame gear set to rotate, the two worms also rotate synchronously, thereby driving the worm wheel connecting rod 5 to rotate, thus realizing the height change of the four-bar linkage.

[0170] In this embodiment, a plow-like braking is achieved by extending the left and right sliding legs into a V-shape.

[0171] In this embodiment, during the rotation process, the toe 1-1 contacts the ground and applies forward thrust through friction. To make this process smoother and more stable, the toe 1-1 is made of a flexible material and is attached to the tail foot.

[0172] In this embodiment, the first drive component adopts a three-stage gear transmission chain (G5→G7→G6), with the left gear G7 and the right gear G6 meshing in opposite directions. Together with the guide rail slider mechanism (3-4), they form a differential drive system. When the first motor M3 drives, the left and right shoulder frames generate synchronous reverse oscillations with a 180° phase difference. The guide rail slider mechanism converts the rotational motion of the gears into linear displacement, allowing the skis on both sides to form a precise V-shaped unfolding angle (adjustable from 0° to 45°). This design enables the robot to quickly respond to posture adjustment needs and achieve controllable snowplow braking in skiing mode. Furthermore, by optimizing the gear transmission ratio (G5:G7:G6 = 2:1:1), the robot's braking response time is shortened to 0.3 seconds, significantly improving braking stability and solving the problems of slow braking response and poor stability in traditional skiing robots.

[0173] In this embodiment, the rotating central shaft 8, the worm gear 15, and the turbine connecting rod 5 constitute a nested transmission module. The turbine connecting rod adopts a parallelogram four-bar linkage design, forming a floating connection with the ski. When the second motor M5 on the left shoulder frame is driven, the worm gear transmission achieves a 30:1 reduction ratio, converting the motor's rotational motion into the vertical lifting and lowering of the ski (stroke ±80mm). The parallel motion characteristics of the turbine connecting rod ensure decoupling control of the ski's attitude angle (±15°) and height, realizing a biomimetic gait cycle of "lift-extend-press down".

[0174] In crawling mode, ground contact force fluctuations are reduced by 60%, significantly improving the ability to navigate complex terrain and solving the problems of poor motion stability and insufficient terrain adaptability of traditional robots.

[0175] In this embodiment, the tailfoot mechanism employs a dual-motor independent drive (M1 / M2), configured with a series structure of a rigid foot body (1-2) and a flexible toe (1-1). The toe is made of silicone-carbon fiber composite material (Shore hardness 35A). In gliding mode, the flexible toe achieves point propulsion through deformation energy storage (contact time 200ms, peak impact force reduced by 40%). In crawling mode, the rigid foot body provides stable support (support force ≥50N), and in-situ turning is achieved through dual-motor differential control (minimum turning radius 0m). This approach overcomes the terrain adaptability limitations of traditional mobile mechanisms, improving passability on mixed ice and rock surfaces by 85%, and resolving the contradiction between mobility efficiency and stability in multi-terrain environments.

[0176] In this embodiment, the left and right swing brackets achieve ±90° rotational freedom through crossed roller bearings, forming a double-row tapered roller bearing support structure with the shoulder frame body. The crossed roller bearings feature rollers arranged perpendicularly to each other at 90° intervals, with spacers between the rollers to prevent tilting and mutual friction. When the first motor M4 of the left shoulder frame drives the skis, the gear set (G1 / G2) achieves a 1:2 transmission ratio, enabling the skis to perform ±45° lateral swing (for steering) and maintain ±15° longitudinal tilt (for edge control). The high-precision rotational characteristics of the crossed roller bearings ensure the stability of the swing bracket during rotation, achieving precise control of skiing movements. In this way, the high load-bearing capacity (capable of withstanding axial and radial loads), low coefficient of friction (energy saving and efficiency), and high rigidity (increasing overall rigidity) of the crossed roller bearings enable high-precision, low-wear motion control of the swing bracket within a ±90° rotation range. It can maintain an attitude control accuracy of 0.5° even when gliding at high speed (≥8m / s), which solves the contradiction between the motion stability and maneuverability of the ski robot.

[0177] In this embodiment, the left and right shoulder frames are connected to the central frame via drive shaft assemblies, employing a double parallelogram linkage mechanism, allowing the effective extended length to reach 1.8 times that of the basic frame. When driven by the first motor M3, the left and right bodies achieve synchronous expansion (0.6 m / s) and independent angle adjustment (±10°), forming a "forward extension-support-retraction" peristaltic gait in crawling mode. This design enables the robot to flexibly adapt to different terrains and achieve efficient movement. Using this method, the center of gravity fluctuation is reduced by 55% when crossing vertical obstacles, significantly improving obstacle-crossing ability and solving the balance problem between obstacle-crossing ability and movement efficiency in traditional legged robots.

[0178] In this embodiment, the worm gear transmission mechanism integrates an electromagnetic brake (rated torque 5 Nm), which can recover 30% of the potential energy during the crawling descent phase. When the ski descends from its highest point (80 mm), the torque of the worm shaft is converted into electrical energy and stored via a generator. Combined with the damping characteristics of the flexible toe, the energy consumption per gait is reduced by 18%, extending the robot's endurance. By employing this method, through energy recovery of potential energy, the robot's endurance is extended to 2.3 times that of traditional designs, solving the energy efficiency problem of mobile robots in complex environments.
