摘要： A blower body is provided with a first wall and a second wall, and openings are provided in the walls at positions facing the approximate center of a diaphragm. An inflow passage that allows the openings to communicate with the outside is arranged between the two walls. When the diaphragm is vibrated in response to a voltage applied to a piezoelectric element, the first wall vibrates near the opening and sucks in air from the inflow passage so that the air can be ejected from the opening. A plurality of branch passages which provide sound absorption are connected to an intermediate section of the inflow passage so as to prevent noise generated near the opening from leaking from an inlet.

摘要： An overturn prevention control device includes a bicycle robot capable of freely laterally inclining, an angular velocity sensor mounted on the bicycle robot such that a detection axis thereof extends in a substantially longitudinal direction of the bicycle robot, a motor mounted on the body such that a rotating shaft thereof extends in a substantially longitudinal direction of the body, a rotation sensor that detects a rotational position or a rotational speed of the motor, and an inertial rotor coupled to the rotating shaft of the motor. The overturn prevention control device corrects inclination of the bicycle robot by rotating the inertial rotor using the motor and by utilizing a reaction torque occurring when the inertial rotor is rotated. The overturn prevention control device further includes an inclination angle estimating portion arranged to estimate an inclination angle relative to a balanced state from an angular velocity output ω1 from the angular velocity sensor and a torque command τ0 to be supplied to the motor. The overturn prevention control device corrects inclination of the bicycle robot using an estimate of the inclination angle.
摘要翻译：防翻倒控制装置包括能够自由地横向倾斜的自行车机器人，安装在自行车机器人上的角速度传感器，使得其检测轴沿自行车机器人的大致纵向方向延伸，安装在主体上的马达，旋转轴沿主体的大致纵向方向延伸，旋转传感器检测电动机的旋转位置或转速，以及耦合到电动机的旋转轴的惯性转子。翻转防止控制装置通过使用马达旋转惯性转子并利用当惯性转子旋转时产生的反作用力来校正自行车机器人的倾斜度。翻转防止控制装置还包括倾斜角度估计部分，其布置成从角速度传感器的角速度输出ω1> 1估计相对于平衡状态的倾斜角度，以及扭矩指令ττ 0 提供给电机。翻倒防止控制装置使用倾斜角度的估计来校正自行车机器人的倾斜度。
