    • A charging system for a walking robot which charges a battery mounted on the walking robot by connecting a power supplying connector provided in a charging station to a power receiving connector in the walking robot, wherein the walking robot is capable of moving without significant restrictions during charging. The charging system includes a lock mechanism for locking the power supplying connector to the power receiving connector. A connector holder holds the power supplying connector detachably, an advancing/retracting mechanism advances and retracts the connector holder in the anteroposterior direction, and a lock operation mechanism performs a lock operation and an unlock operation of the lock mechanism via the connector holder. After an advance of the connector holder, the lock mechanism performs the lock operation to lock the power supplying connector to the power receiving connector. Thereafter, the connector holder is retracted out of the power supplying connector.
    • 一种用于步行机器人的充电系统,其通过将设置在充电站中的供电连接器连接到步行机器人中的受电连接器而对安装在步行机器人上的电池进行充电,其中,步行机器人能够在充电期间能够移动而没有显着的限制 。 充电系统包括用于将电力供应连接器锁定到电力接收连接器的锁定机构。 连接器保持器可拆卸地保持供电连接器,前进/后退机构在前后方向前进和后退连接器保持器,并且锁定操作机构经由连接器保持器执行锁定机构的锁定操作和解锁操作。 在连接器保持器的前进之后,锁定机构执行锁定操作以将供电连接器锁定到电力接收连接器。 此后,连接器支架从电源连接器中退出。
