This paper presents the development of optimal takeoff maneuvers for an AC75 foiling sailboat competing in oldest and most prestigious competition world, America’s Cup. The many challenges to developing these due its nonlinear, high-dimensional, highly unstable dynamics. During maneuver, boat starts water with low speed (displacement mode) increases until it reaches steady-state (the hull stays...

Achieving short-distance flight helps improve the efficiency of humanoid robots moving in complex environments (e.g., crossing large obstacles or reaching high places) for rapid emergency missions. This study proposes a design flying robot named Jet-HR2. The has 10 joints driven by brushless motors and harmonic drives locomotion. To overcome challenge stable-attitude takeoff small thrust-to-wei...
