Problems solved by technology

However, too many crawlers will inevitably increase the volume of the robot, and at the same time, the driving speed will also decrease
Therefore, in a narrow area environment, the application of crawler search and rescue robots poses a difficult problem

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Figure 1a -b is the overall schematic diagram of the variable crawler search and rescue robot. It can be seen from the figure that the search and rescue robot is a crawler vehicle structure, mainly composed of car body 1, driving wheel 2, movable driven wheel 7, fixed driven wheel 8, variable Crawler belt 6 and other auxiliary components form.

[0020] The interior of the car body 1 is equipped with a power supply, driving motors and devices for driving devices, robot control devices, and various sensor processing circuits. A camera 3 is installed on the top of the car body, a microphone 9, car lights 10 and sensors are installed at the front, and voice is installed at the rear. trumpet. The crawler driving device is installed on the drive shaft of the car body, and the two drive shafts have their own drive motors, which can realize th...

Abstract

The invention provides a small-sized variable crawler type search and rescue robot, comprising a body, a crawler travelling device, a communication device and a signal acquisition device, wherein the body is a carrier for the crawler travelling device, the communication device and the signal acquisition device; the crawler travelling device comprises a retractable crawler, a driving wheel and a retractor device; the retractor device is a slipper rocker mechanism consisting of two movable driven wheels, two fixed driven wheels and two linear push rods; the driving wheels are driven by driving shafts on the body, a linear push rod motor is taken as a slider and drives rockers and the movable driven wheels thereon to rotate around the fixed driven wheels so as to drive the crawler to stretch and shrink, thus forming a certain angle in the forward to backward direction of the crawler. The robot of the invention has small volume and flexible movement and can run forwards and backwards and turn in narrow space. The variable crawler can form certain angles in the forward to backward direction, thereby being beneficial to realizing obstacle detouring, reducing the volume of the crawler type search and rescue robot and improving the running speed of the robot.

Description

technical field [0001] The invention relates to a robot, in particular to a variable crawler search and rescue robot. Background technique [0002] At present, earthquakes, fires, mine accidents and other disasters occur frequently, seriously threatening human property and life safety, and have aroused widespread concern. Searching for survivors in the ruins is an urgent task for rescuers. However, after the disaster, the narrow space formed in the ruins made it impossible for search and rescue personnel and even search and rescue dogs to enter, which brought great difficulties to search and rescue. Quickly and accurately searching and rescuing victims in the narrow passages of the ruins not only made it possible for the victims to Get timely and effective rescue, at the same time, reduce the rescue manpower and material resources, and increase the safety of rescue operations. Search and rescue robots can solve the above problems very well. [0003] The terrain conditions...
