Based on the deformation technology of deformation robot,the concept design of deformable underwater glider is introduced into the design of traditional bionic robot crab.The bionic robot crab can switch its working mode ac-cording to different work tasks.Based on the viscous fluid theory,the sliding grid method and the multi domain method are combined efficiently to study the hydrodynamic performance of the crab like robot crab with complex appendage structure,obtain the lift drag characteristics at different speeds and angles of attack,and analyze the distribution of its pressure field,velocity field and vorticity field.The optimal angle of attack of the bionic robot crab in gliding mode is obtained,which lays a foundation for the optimal design of the bionic robot crab.
