    • A brake system includes a front and a rear wheel brake circuit which are independent of each other. Each circuit includes: a master cylinder connected to a brake caliper through the main brake line; a hydraulic pressure modulator which causes an electrically-operated motor to generate hydraulic pressure; and a normally-open electromagnetic on-off valve. When the two brake circuits are moved in response to operation of a braking operation unit in one circuit, in the brake circuit for which a braking operation unit was operated earlier, the electromagnetic on-off valve opens so that the brake caliper is operated by use of hydraulic pressure from the master cylinder. In the other brake circuit, the electromagnetic on-off valve is closed so that the brake caliper is operated by use of hydraulic pressure from the hydraulic pressure modulator. The braking system uses simple wheel braking mechanism and piping, and concurrently reduces electric current consumption.
    • 制动系统包括彼此独立的前轮和后轮制动回路。 每个回路包括:通过主制动线连接到制动钳的主缸; 液压调节器,其使电动马达产生液压; 和常开电磁开关阀。 当两个制动电路响应于一个电路中的制动操作单元的操作而移动时,在制动操作单元早先操作的制动回路中,电磁开关阀打开,使得制动钳通过使用操作 的主缸液压。 在另一个制动回路中,关闭电磁开关阀,使得制动钳通过使用来自液压调节器的液压来操作。 制动系统使用简单的车轮制动机构和管道,同时降低电流消耗。

    • A system for controlling the locomotion of a biped walking robot having a body and a pair of legs each connected to the body through a hip joint and having a knee joint and an ankle joint and a foot at its distal end in accordance with predetermined locomotion data including a foot landing position of a lifted leg. A 6-dimensional force and torque sensor is provided at the body to detect an external force exerted on the robot. A moment is calculated from the external force and integrated during the external force exists. A coefficient is further determined in accordance with the trajectory of the lifted leg and is multiplied to the integrated moment. The predetermined foot landing position is corrected in response to the product and control values for the associated drive joints are changed such that the lifted leg will land at the corrected position, whereby preventing the robot from losing its stability when the external force exerts on the robot.
    • 一种用于控制具有身体和一对腿的双足步行机器人的运动的系统,每个腿部通过髋关节连接到身体,并且根据预定的运动数据在其远端处具有膝关节和踝关节以及足部 包括抬起腿的脚部着陆位置。 身体上设置有一个六维的力矩传感器,用于检测施加在机器人上的外力。 一时刻是由外力计算出来的,并在外力存在的情况下积分。 根据提升腿的轨迹进一步确定系数,并将其乘以积分力矩。 响应于产品来校正预定的脚着陆位置,并且改变相关联的驱动关节的控制值,使得提升的腿将在校正位置处降落,由此当外力施加在机器人上时防止机器人失去其稳定性 。
