Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0051] A wheelchair robot consists of a seat and a mobile platform 6. Wherein the seat is installed on the mobile platform 6, and moves with the mobile platform 6.

[0052] Above-mentioned seat is adjustable lifting seat, and it can adopt common seat in the prior art. In this embodiment, the seat is mainly composed of a chair body 1 , an armrest 2 , an elevating adjustment rod 3 , an elevating and rotating pillar 4 , a chair base 5 , a hand control button 16 and a pillar tray 17 . The chair back of the chair body 1 can be flipped forward and folded by 90°. For example, after the chair base 5 and the mobile platform 6 are separated up and down, the components formed by the former can serve as ordinary seats. If the chair b...

Abstract

The invention discloses a wheelchair robot and an indoor autonomous navigation method thereof. The method comprises the following steps: sensing the environmental information through a monocular vision sensor, and constructing a three-dimensional point cloud map for the obtained environmental features by use of a vision SLAM algorithm; performing storage, perfection and rasterization treatment onthe formed point cloud map; loading the treated raster map, and performing self-localization of a moving wheelchair robot by the Monte-Carlo algorithm; finally, while performing continuous localization, finishing global path planning and local dynamic path planning by the wheelchair robot in the navigation process by combining the ant colony algorithm and the dynamic raster algorithm. The method disclosed by the invention can realize autonomous navigation of a wheelchair.

Description

technical field [0001] The invention relates to the technical field of wheelchair robots, in particular to a wheelchair robot and an indoor autonomous navigation method thereof. Background technique [0002] At present, most of the wheelchairs used in daily life have single functions and many links that require human participation. However, the existing intelligent wheelchairs are often not widely popularized due to factors such as high production costs, complex structures, and insufficient code reuse rate. Although there are currently some wheelchairs that can be manually controlled, frequent manual manipulation is still required during the wheelchair's travel, and its own obstacle avoidance and navigation also require human real-time monitoring operations, which makes the degree of autonomy not high. Contents of the invention [0003] The present invention aims to solve the problem that existing wheelchairs need manual control and cannot navigate automatically, and prov...
