Abstract：[Objective]To solve the problems of high impact force and unstable landing of existing jumping robots,a jumping robot with a new type of buffer device was designed.[Methods]Firstly,a stopping mechanism in the buffer device was proposed to reduce the landing impact,and a combination of one-way bearings and damping rings was used to avoid the rebound of the body caused by the absorption of ground impact force by the buffer device.Secondly,based on the structural form and jumping principle of the robot,the main structure of the jumping robot was established,and the buffering mechanism was analyzed.The three-dimensional solid model of the jumping robot was built on the SolidWorks platform.Finally,based on the Adams platform,motion simulation was conducted on the bouncing process of the jumping robot,and a comparative analysis was conducted on the landing stability and impact of the robot with and without a stopping mechanism and a variable damping buffer mechanism in the buffer device.[Results]The research results indicate that the robot has good stable jumping and landing buffering capabilities,which can reduce the risk of body rebound and overturning caused by the instantaneous release of elastic potential energy,thereby causing damage to components.
