Abstract: |
Hydrodynamic force is an important factor that affects the performance of underwater vehicle. Adapting to the current underwater environment by changing its shape is an important feature of underwater snake-like robots (USLR). An experiment was implemented to verify the swimming along the straight line of USLR. A simulation platform is also established for the analysis of the swimming of USLR. To figure out adaptive swimming of USLR to different underwater environments, the relationships between CPG parameters and maximum swimming speed have been discussed, and the switching between different swimming modes has been implemented. |
Key words: underwater snake-like robot Kane dynamic model central pattern generator (CPG) adaptive swimming maximum swimming speed |
