Problems solved by technology

For the mobile robot navigation platform that simulates the ground and space environment, there are still many problems in the wheel, which is the key component of the robot's walking. Environment such as hard ground, soft ground and sandy ground
(2) The ability to perceive the environment is poor, and the wheels do not have the ability to perceive environmental parameters such as temperature and obstacles
(3) In the sandy environment, for the same wheel, its traction and steering resistance cannot be taken into account
That is, the comprehensive performance of traction and steering is poor

Abstract

The present invention relates to the improvement of wheel structure for mobile navigation platform. In the perceptive bionic sands wheel capable of being reconfigured for mobile navigation platform, there are outside elastic rim board fixed outside the hub camber, inside elastic rim board fixed inside the hub camber, elastic tyre set inside the central line of the rim capable of being reconfigured, perception sensor reflecting devices set in the equal interval inside the elastic tyre, and perception sensor sending devices set in the equal interval on the rack camber. The present invention has the advantages of simple and compact structure, improved linear running stability and turning performance, increased contact area to ground, capacity of suiting various environment, relatively high passing capacity in sandy environment, environment temperature and obstacle sensing capacity, etc.

Description

Technical field: [0001] The invention relates to an improvement of the wheel structure of a mobile navigation platform. Background technique: [0002] Wheeled running mechanism is widely used in mobile robots and vehicles because of its simple and reliable structure, high-speed stability, high energy utilization rate, good maneuverability and good passability. For the mobile robot navigation platform that simulates the ground and space environment, there are still many problems in the wheel, which is the key component of the robot's walking. environment such as hard ground, soft ground and sandy ground. (2) The ability to perceive the environment is poor, and the wheels do not have the ability to perceive the parameters of the environment such as temperature and obstacles. (3) In the sandy environment, for the same wheel, its traction and steering resistance cannot be taken into account. That is, the comprehensive performance of traction and steering is poor.
