Title   The design of the four wheel reconnaissance robot                  

ABSTRACK

  The primary coverage about the design of the four wheel reconnaissance robot is what the study about this topic at present and what the significance or purpose of this objective.Besides what the project discussed at home and abroad is also what we interested about.What is more is the analysis of this the four wheel reconnaissance robot and the design of the principle.Also,it is contained the selecting and using of the standard parts and the design of the pivotal parts which is be checked.Though consulting the related experience of the robot changing its vehicle width which makes some improvements in this dissertation.What is more is that the article is also contained the analysis,the calculation and the confirmation. The key point of this design is about the part of the movement in this mechanism.It is adopted the push rod mechanism for its mainly way of working.The design of the robot changing its vehicle width consists of two parts,including the push rod mechanism part and the power part.It adopts servo motor to provide power support.It is be pay attention about the power part and the push rod mechanism part’s analysis in this design.In this dissertation it makes a detailed designed and calculation about these parts which are primary and mainly.It also makes an demonstrate about the robot of changing vehicle width on virtual prototype.           

Keywords:  robot,reconnaissance,push rod mechanism
