Environmental adaptive control of a snake-like robot with variable stiffness actuators

IEEE/CAA Journal of Automatica Sinica, 2020
This work investigates adaptive stiffness control and motion optimization of a snake-like robot with variable stiffness actuators. The robot can vary its stiffness by controlling magneto-rheological fluid ( MRF ) around actuators. In order to improve the

Estimation of Fluid Forces on a Snake-like Robot Swimming in Viscous Fluids Considering Boundary Layer Thinning

IEEE/SICE International Symposium on System Integration, 2023
Snake-like robots can move not only on dry ground but also in various environments such as water, mud, and clay due to its undulating motion. When a snake-like robot moving in such an environment is modeled by a numerical model including the fluid ...

Recursive inverse dynamics of a swimming snake-like robot with a tree-like mechanical structure

Workshop on Advanced Robotics and its Social Impacts, 2023
In this paper, we report a recursive inverse dynamical model for a new snake-like robot called NATRIX. This robot has been designed to maintain its gaze on the water surface and monitor sensible ecosystems.
