چکیده

Underwater soft robots are challenging to model and control because of their high degrees freedom intricate coupling with water. In this letter, we present a method that leverages the recent development in differentiable simulation coupled differentiable, analytical hydrodynamic assist modeling an underwater robot. We apply Starfish, customized robot design is easy fabricate intuitive manipulate. Our starts data obtained from real alternates between experiments. Specifically, step uses gradients simulator run system identification trajectory optimization, experiment executes optimized on collect new be fed into simulation. demonstration Starfish shows proper usage not only narrows down its simulation-to-reality gap but also improves performance open-loop controller

Fuzzy Trajectory Control Design for Underwater Robot

The URV is operated manually with a joystick or automatically with a computer. The automatic control of the underwater robot is a difficult problem due to its nonlinear dynamics. Moreover, the dynamics can change according to the alteration of configuration to be suited to the mission. In order to cope with those difficulties, the control system should be flexible. An interesting review of clas...
