Problems solved by technology

When the former wheeled motion mechanism encounters obstacles such as fences and stairs, the movement will be restricted; and for round wheels, when the height of the obstacle is higher than the center of mass of the motion mechanism, it is very difficult for it to move forward. Poor sex
The latter adopts a crawler type, and its structure is complex, its movement speed is relatively low, its efficiency is low, its movement noise is large, and its flexibility is poor.

Embodiment Construction

[0007] Such as figure 1 , figure 2 As shown, the benzene invention is an unmanned ladder climbing robot, including a deformation wheel 26, a planetary wheel 5, an electromagnetic clutch 7, a speed reducer 9, a rear shock absorber 14, a front shock absorber 24, a chassis 15 and a center of gravity Adjusting mechanism 29, steering mechanism 37, when the robot is running on a flat road, the deformed wheel 26 is a circular wheel type; there is also a DC motor 8 that can drive the robot forward, stop or retreat, and the third wheel that controls the steering of the robot. Steering gear 12, the ultrasonic sensor 21 that acquisition signal is sent to the single-chip microcomputer to the real-time processing of collected signal, the second steering gear 17 that can make deformation wheel 26 deform, is used to adjust the center of gravity adjustment mechanism 29 when the robot climbs the stairs. One steering gear 27.

Abstract

An unmanned ladder climbing robot comprises deforming wheels (26), planet wheels (5), an electromagnetic clutch (7), a reducer (9), a rear damper (14), a front damper (24), a chassis (15), a gravity center adjusting mechanism (29) and a steering mechanism (37). When the robot runs on the level road, the deforming wheels (26) are round wheels. The unmanned ladder climbing robot further comprises a direct current motor (8) driving the robot to move forwards, stop or move backwards, a third steering engine (12) for controlling the robot to turn, an ultrasonic transducer (21) for collecting signals and transmitting the signals to a single-chip microcomputer to be processed in real time, a second steering engine (17) enabling the deforming wheels (26) to deform, and a first steering engine (27) used for adjusting the gravity center adjusting mechanism (29) when the robot climbs a ladder.

Description

technical field [0001] The present invention relates to a robot for stair climbing. Background technique [0002] The unmanned ladder climbing robot uses the artificial intelligence of the robot to realize the ladder climbing work, replaces the manual labor required for low-floor cargo handling, and replaces manual detection, fire protection and It can be used for rescue work, etc., and can also be used for autonomous walking of disabled people. At present, unmanned ladder climbing robots with various structures have been designed at home and abroad. The basic climbing structures include crawler type, wheel type, foot type and composite type. However, it has not been widely used in real life at present. Such as the existing patents: intelligent obstacle-crossing robot based on Bluetooth control (patent number: CN203158114U), internal and external reinforcement structure variable configuration obstacle-crossing robot (patent number: CN103231748A). When the former wheeled m...
