A variable-structure spherical dual-arm search-and-rescue robot

Abstract

The invention requests to protect a variable structural spherical double-arm search and rescue robot which mainly comprises double variable structural mechanical arms and a variable structure spherical shell and has the prominent characteristics that double six-degree-of-freedom mechanical arms are designed on a robot base frame, and by a deformation double-arm mechanism, extension and retraction of the mechanical arms are completed; the robot can be changed into a double-wheel state from a sphere by a deformation spherical shell mechanism, and double mechanical arms can extend by the deformation double-arm mechanism so as to finally complete the integral deformation process; the robot can implement flexible movement by a rolling driving mechanism; in a sphere state, electronic elements of the robot are all packaged in the spherical shell, and thus, the variable structural spherical double-arm search and rescue robot has an excellent self-protection ability and in the searching and rescuing field, corrosion of dust and harmful gas can be effectively prevented; in a deformed state, the mechanical arms can implement a search and rescue operation on the outside, and meanwhile, collaboration of rolling of the spherical shell can reinforce the obstacle climbing ability of the robot in the searching and rescuing field and adaptability of the robot to different terrains.

Description

technical field [0001] The invention relates to the technical field of special robots, in particular to a small spherical search and rescue robot capable of deforming and operating externally. Background technique [0002] At present, timely and effective post-disaster search and rescue capabilities have increasingly been highly valued by countries all over the world, and more and more people are paying attention. Urban bombings, terrorist incidents and natural disasters can cause property damage and casualties. In order to minimize the loss after the disaster, the search and rescue operations in the future cannot be delayed. However, the post-disaster environment is very complex. On the one hand, there are unknown risk factors such as smoke, poisonous gas, collapse, and explosion. In complex and complex environments, it is very difficult to carry out search and rescue work within an effective time. The life safety of search and rescue team members cannot be guaranteed, an...

Problems solved by technology

Among them, crawler robots are the most widely used, with the characteristics of strong obstacle surmounting ability and low pressure on the ground, but the moving speed is slow and the movement efficiency is not high.

Wheeled search and rescue robots have the characteristics of high movement efficiency, fast movement speed and simple structure, but their ability to overcome obstacles is weak

The legged search and rescue robot has the characteristics of strong obstacle-surmounting ability, but the mechanical structure design and control are complicated, and the reliability and stability are low.

Although the spherical search and rescue robot has flexible movement and good self-protection, it has poor external operation ability
