[Abstract]:As an important branch of modern military robot, mobile reconnaissance robot has formed a certain scale product group, and has a good technology accumulation. As a new research direction in recent years, the research prospect of projectile reconnaissance robot is broad. On the basis of collecting and analyzing the existing research results at home and abroad, this paper designs a kind of small projectile reconnaissance robot which can be set up by throwing, aiming at the hardware design and structure design of the robot. The equilibrium stability and kinematics and dynamics analysis have been carried out. Combined with the related products at home and abroad, this paper puts forward the technical index of the projectile investigative robot, which has the advantages of small volume, simple structure and certain ability of surmounting obstacles, and puts forward the overall design scheme of the robot. Based on the design scheme, the workflow and principle of the robot are expounded, the whole structure of the robot is designed, the control system and hardware of the robot are designed, and a complete 3D model is constructed. Aiming at the stability of robot attitude after throwing placement, the structure of the robot is optimized, including the optimization of the centroid layout of the spindle, the development of the balancing technology and the design of the balancing body. The optimization of spindle centroid layout depends on mechanical design software to improve the stability of spindle body. This paper innovates the complex scheme of the stability of traditional inverted pendulum, designs the balance body of auxiliary mechanism, analyzes and optimizes the balance structure with MATLAB software, and emphatically analyzes the principle of restoring balance state of multi-landing robot in complex environment. Aiming at the problem of improving the anti-fall seismic performance of small robot, the lightweight design of the robot is carried out, and the design rationality and reliability of the design are demonstrated by introducing the impact load calculation to optimize the assembly mode of the key parts of the wheel-shaft fit. Aiming at the problem of motion stability and obstacle avoidance performance of wheeled mobile robot, the kinematics model of the robot is constructed, the motion planning and dynamic analysis are carried out, and the dynamic simulation of the robot is carried out by using Adams software. The feasibility of motion planning in various structural environments is verified, especially the feasibility of the robot's position and posture adjustment after the disturbance of obstacle crossing is generated.
