Omni-directional intelligent following luggage case and control method thereof

Abstract

The invention discloses an omni-directional intelligent following luggage case. The omni-directional intelligent following luggage case comprises a transmitting device and a case body; the transmitting device comprises a power supply, a control assembly A and an ultrasonic transmitter; four ultrasonic receivers and a walking device are arranged on the case body; the four ultrasonic receivers are positioned on the same receiving plane; the transmitting device transmits ultrasonic signals to the ultrasonic receivers through the ultrasonic transmitter; the walking device comprises a control assembly B and an omni-directional wheel group; the omni-directional wheel group comprises at least three omni-directional wheels and driving motors corresponding to the omni-directional wheels; the control assembly B transmits driving signals to the driving motors after receiving the signals of the ultrasonic receivers; and the driving motors drive the omni-directional wheels to walk according to the received driving signals. The luggage case greatly improves the accuracy of positioning and tracking processes; and the wheels adopt the omni-directional wheels, so that turning and walking are facilitated.

Description

technical field [0001] The invention relates to an all-round intelligent following suitcase and a control method thereof, belonging to the technical field of intelligent control. Background technique [0002] With the rapid development of social modernization, the accelerated pace of people's work, and the continuous improvement of people's requirements for the quality of life, business trips and travel have become an indispensable part of everyone's work and life. During business trips or travel, many people will worry about carrying heavy suitcases. At present, most of the suitcases are of pull-rod type, which need to be manually dragged and dragged, which consumes physical strength and is inconvenient during walking. [0003] Though, some intelligent suitcases have also occurred now, but these suitcases still have some defects, mainly contain: (1) can only use single sensor usually: as carrying out obstacle avoidance rather than following with bluetooth sensor. (2) Some...

AI Technical Summary

Problems solved by technology

At present, most of the suitcases are pull-rod type, which need to be manually dragged and dragged, which consumes physical strength and is inconvenient in the process of walking

[0003] Although some smart suitcases have also appeared now, there are still some defects in these suitcases, mainly including: (1) usually only a single sensor can be used: such as using bluetooth sensors for obstacle avoidance instead of following

(2) Some ultrasonic devices have only three receivers, their positioning is not accurate, and their responses are not sensitive. Only one set of rough values ​​can be obtained, but not accurate values.

(3) It cannot be moved in all directions, so it is inconvenient
