摘要： The invention provides a synchronism establishing method and apparatus including a plurality of modules having different independent synchronization patterns to be switched wherein the switching transition process having a time length corresponding to the number of protection stages necessary for pull in and protection of synchronism is reduced so small that the presence of such switching transition process can be ignored while assuring similar advantages to those of conventional synchronism establishing apparatus. A master side module delivers a notification of establishment of synchronism thereof to a slave side module. When the slave side module is in a condition wherein synchronism is established, it puts its synchronizing operation into a waiting mode. Even if it thereafter detects a number of abnormal synchronization patterns greater than the number of protection stages, it does not determine a pull out condition and maintains the pulled in phase. If the slave side module detects a false pull out condition from the master side module, the slave side module determines that synchronism is entered therewith and resumes its processing operation.

摘要： A charging system for a legged mobile robot that facilitates positioning of a robot to be charged and does not put a load on the robot is provided. The charging system includes a battery 2, a power receiving connector 4 and a movable shutter member 5 capable of being opened and closed on a rear cover 3, which are provided on a robot 1, and a holder 21, a power supplying connector 22, a slide mechanism 23, a base plate 25, a charging power supply 26 and the like, which are provided on a charging station 20. The robot 1 performs a predetermined positioning on the base plate 25 and then moves the center of gravity rearward to connect the power receiving connector 4 to the power supplying connector 22. In this step, when the rear cover 3 of the robot 1 is guided by a first guide section 21a of the holder 21, the slide mechanism 23 allows the holder 21 to move horizontally. Thus, even if the robot 1 and the charging station 20 are slightly misaligned with each other, the robot 1 can be easily positioned correctly.
