Problems solved by technology

However, the two types of tires have certain defects. Due to the complexity of the composition structure, the reliability of the system is low, the cost is high, and it is difficult to manufacture small sizes. In addition, because there are multiple rotating wheels, in order to prevent dust from blocking the rotation, therefore higher for the environment
The above defects have caused the two types of tires to be unable to be used in many environments.

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 , figure 2 As shown, the present invention includes a platform base 1, wheels 2, a motion execution unit 3 and a motion control unit 4, wherein the motion control unit 4 is arranged above the platform base 1, and four motion execution units 3 pass through the bottom of the platform base 1. Four wheels 2 are installed, and each motion executing unit 3 is connected with a motion control unit 4 . The tire tread of the wheel 2 includes a contact surface M and an inclined surface N, the two sides of the contact surface M are respectively provided with an inclined surface N inclined to the wheel axis 10, the contact surface M is a cylindrical surface, and the contact surface M The slope N on both sides is a semi-ellipsoid structure. Both the contact surface M and the slope N (that is, the outer surface of the ellipsoid) are provided with...

Abstract

The invention belongs to the technical field of mobile equipment, and in particular relates to a mobile platform. It includes platform base, wheels, motion execution unit and motion control unit, wherein the motion control unit is set above the platform base, and four wheels are installed on the bottom of the platform base through four motion execution units, and each motion execution unit is connected with the motion connected to the control unit, the tire tread of the wheel includes a contact surface and a slope, the two sides of the contact surface are respectively provided with slopes inclined to the wheel axis, and the contact surface and the slope are provided with diagonal lines inclined in the same direction . The invention can reduce the cost, meet the requirement of small size, reduce the requirement of the application environment, and has the characteristics of simple structure, etc., and greatly increases the achievable scope of the application of the omnidirectional mobile platform due to the spiral tire with the obstacle-surmounting function.

Description

technical field [0001] The invention belongs to the technical field of mobile devices, and in particular relates to a mobile platform. technical background [0002] The omnidirectional mobile platform refers to a platform that can move along the XY direction and can rotate in situ. It has the advantages of small steering space and independent movement in the XY direction. It can be widely used in industries, toys, robots, etc. involving wheel drive. mobile platform. The existing omnidirectional mobile platform methods based on tires include the Mecanum wheel method and the omnidirectional wheel method. The tire structure of the two is similar, and both are composed of active hubs and multiple wheels evenly distributed in a certain direction on the outer edge of the hubs. Of course, when the two are moving in all directions, the distribution of the tires on the platform is different, and they are parallel installation and orthogonal installation respectively. However, the t...
