Robot controlling apparatus and robot controlling method

A robot controlling apparatus for controlling a robot body which runs on power supplied from an auxiliary power supply when a main power supply fails, the robot controlling apparatus comprising:

• an operation controlling unit constructed to divide a series of operations of the robot body into a plurality of operation blocks in advance and cause the robot body to perform operations sequentially from one operation block to another using power supplied from the main power supply;
• an operation identifying unit constructed to identify an operation block being processed at a time of a failure of the main power supply from the plurality of operation blocks when the main power supply fails;
• an operation continuing unit constructed to cause the robot body to continue operation using the power supplied from the auxiliary power supply, until the operation corresponding to the operation block being processed at the time of the failure of the main power supply is finished;
• and
• an operation stopping unit constructed to cause the robot body to stop operation, when the operation block being processed at the time of the failure of the main power supply is finished, until the main power supply is restored from the failure, wherein
• when the main power supply is restored from the failure, the operation controlling unit causes the robot body to resume operation beginning with a start point of an operation block next to the operation block being processed at the time of the failure of the main power supply.
