Assignee: SEIKO EPSON CORPORATION
Field: Handling (Mechanical engineering)
Classification: CPC B  Y | IPC B

Claim 5:
6. A control device configured to control a robot driven using a battery as a power supply source, comprising:
a voltage acquisition section configured to obtain an output voltage of the battery; and
an upper-limit number-of-times storage section configured to store an upper-limit number of times which is an upper limit of a number of times the robot can be made to execute an operation in a period from when the battery is fully charged to when the battery is recharged, wherein
the control device executes a setting process of making the robot repeatedly execute the operation from when the battery is fully charged to when the output voltage of the battery obtained by the voltage acquisition section becomes not higher than a predetermined threshold value to obtain a number of times the robot executed the operation within a range in which the output voltage of the battery is higher than the threshold value, and then storing the number of times obtained in the upper-limit number-of-times storage section as the upper limit number of times,
the control device obtains the output voltage of the battery after the number of times the robot is made to execute the first operation reaches the first upper-limit number of times in the period from when the battery is fully charged to when the battery is recharged, and executes a correction of decreasing the first upper-limit number of times when the output voltage of the battery obtained is not higher than the threshold value.
