Device and method for automatically adjusting height of vehicle body of mobile robot

Abstract

The invention discloses a device and method for automatically adjusting the height of a vehicle body of a mobile robot. The device comprises a box, a transmission mechanism and a robot control system, wherein the transmission mechanism is arranged in the box, and the robot control system is used for controlling the transmission mechanism to rotate forwards or backwards according to obstacle height data information. The outer bottom of the box is movably hinged to a vehicle frame through a four-bar mechanism, a rope is connected between the transmission mechanism and the vehicle frame, the transmission mechanism rotates to change the length of the rope, and the four-bar mechanism is driven to perform stretched-out or drawn-back motions. The device can be applied to the field of amphibious mobile robot devices, data information of the mobile robot control system is received by the device, a motor is adopted for driving a gear shaft through a reduction gear, the gear shaft rotates to tension the rope, and the height of the vehicle body of the mobile robot is reduced in cooperation with the four-bar mechanism; when the rope is released, the four-bar mechanism is drawn back under the effect of the tension of a tension spring, and the effect of increasing the height of the vehicle body of the mobile robot to automatically adjust the height of the vehicle body of the mobile robot is achieved.

Description

technical field [0001] The invention relates to height adjustment of a mobile robot, in particular to a device and method for automatically adjusting the height of a mobile robot body. Background technique [0002] With the advancement of science and technology, more and more mobile robots are applied to various fields, such as home services, ocean development, nuclear power inspection and maintenance, mine search and rescue, and explosive discharge. There are many obstacles in these unknown environments. In order to successfully complete the task instead of humans, the robot must effectively avoid these obstacles. The common solution is to fix the height of the robot body and let the robot move along the side of the obstacle. When the height of the obstacle is not very high, this method is used. The general method appears to be inefficient, so in order to solve this problem and improve the efficiency of the mobile robot, it is necessary to redesign a mechanism that can adju...
