The development of a navigation system for autonomous robotic sailing is a particularly challenging task since the sailboat robot uses unpredictable wind forces for its propulsion besides working in a highly nonlinear and harsh environment. the water. Toward solving the problems that appear in this kind of environment. we propose a navigation system which allows the sailboat to reach ... https://www.bekindtopets.com/mega-super-2-Button-Hand-Control-for-the-Mega-Motion-Lift-Chairs-ELEASMB7120027-save-more/
