A shape-controllable humanoid robot based on segmented skin

Abstract

The invention discloses a shape-controllable dress form robot based on segmented skins. The dress form robot comprises a plurality of parts which respectively simulate the shapes of buttocks, the chest, the waist and shoulders, wherein each part is composed of an inner shape driving module of a multilayer structure and an outer skin characterized by a segmented curved surface. Each inner shape driving module is composed of a plurality of spatially distributed linear propelling mechanisms, and the linear propelling mechanisms control the deformation of the segmented curved surfaces. By adjusting the propelling amount of the linear propelling mechanisms, the shape of the segmented curved surface pieces is controlled, and the simulation of the transverse shape of a human body is realized. Therelative distance between adjacent parts is controlled by a displacement adjusting supporting mechanism, so that the simulation of the longitudinal height of the human body is realized. The fitting result of the human body is represented by the tights worn on the robot, and the robot can be used for simulating the shape of the human body of a customer in garment customization and simulating the dressing effect of a real person on a garment by the robot in the online and offline garment sale.

Description

technical field [0001] The invention relates to a fitting robot, in particular a shape-controllable avatar robot based on sliced ​​skins, which simulates the geometric shapes of human bodies of different shapes. Background technique [0002] Clothing online shopping has become an important channel for clothing to circulate in the market. However, limited by the different size standards of manufacturers, it is often difficult for consumers to choose suitable clothing, resulting in a return rate of about 25% for online shopping clothing, which is much higher than other online shopping products. A high return rate not only increases the operating costs of retailers, but also affects the shopping experience of consumers. [0003] At present, there are some human body simulation methods. For example, the Chinese patent "Humanoid Robot Capable of Fitting the Shape of Human Torso" discloses a humanoid robot that can fit the human torso model. The mechanism constructs the shape of...

AI Technical Summary

Problems solved by technology

However, limited by the different size standards of manufacturers, it is often difficult for consumers to choose suitable clothing, resulting in the return rate of online shopping clothing as high as 25%, which is much higher than other online shopping products.

The high return rate not only increases the operating costs of retailers, but also affects the shopping experience of consumers

[0003] At present, there are some human body simulation methods. For example, the Chinese patent "Humanoid Robot Capable of Fitting the Shape of Human Torso" discloses a humanoid robot that can fit the human torso model. The mechanism constructs the shape of the human torso, but the fitting effect of the transition part is poor

For example, the U.S. patent "method and system for custom tailoring and retail sale of clothing" discloses an electromechanical system capable of simulating the shoulders and chest of the human body. The elastic skin is controlled by a linear controller, so that the system can control the shoulders in six directions: up, down, left, and right. Directional deformation, its disadvantage is that its skin is not divided into blocks, and the control is unstable

For example, the Chinese patent "A Robot Model" discloses a robot model that can enhance the authenticity of virtual fittings, through 21 stepping motors to realize the robot model's neck circumference, shoulder width, shoulder thickness, arm circumference, chest circumference, Waist circumference, hip circumference, shoulder-to-chest distance, chest-to-waist distance, waist-to-hip distance and other ten human body parameters are controlled, but the control of a single skin is only controlled by the skin position and lacks skin shape control
