Abstract

A control device includes a processor. The processor controls an electric power supply to an operating part, and charging and discharging of a secondary battery; estimates electric power being supplied to the operating part and the secondary battery; acquires a charge state for a case of charging the secondary battery; and when a determination is made that the electric power estimated by the processor and being supplied to the operating part and the secondary battery is less than electric power required for a predetermined action to be executed by the operating part and, also, the charge state of the secondary battery is a predetermined charge state, controls so as to limit the predetermined action.

Claims (43)

1 . A control device comprising:

a storage; and

a hardware processor which, under control of a program stored in the storage, executes processes comprising:

controlling (i) an electric power supply to an operating part, and (ii) charging and discharging of a secondary battery;

estimating an amount of electric power being supplied to each of the operating part and the secondary battery;

acquiring a charge state of the secondary battery; and

in response to determining that (i) the amount of electric power estimated in the estimating is less than an amount of electric power required for a predetermined action to be executed by the operating part, and (ii) the charge state of the secondary battery acquired in the acquiring is a predetermined charge state, controlling so as to limit the predetermined action.

2 . The control device according to claim 1 , wherein:

the predetermined action is an intermittent action executed intermittently by the operating part, and

the processor controls to limit the intermittent action by making an interval of the intermittent action greater than an interval of the intermittent action when the charge state of the secondary battery is not the predetermined charge state.

3 . The control device according to claim 2 , wherein:

the control device is provided in a robot including the operating part,

the control device controls operation of the robot, and

the predetermined action is a breathing action.

4 . The control device according to claim 2 , wherein:

the predetermined action includes an action of driving a motor, and

the processor controls to limit the predetermined action by controlling so as not to perform the action of driving the motor.

5 . The control device according to claim 2 , wherein the processor estimates the amount of electric power based on an elapsed time from an end of an action other than the predetermined action.

6 . The control device according to claim 1 , wherein:

the control device is provided in a robot including the operating part,

the control device controls operation of the robot, and

the predetermined action is a breathing action.

7 . The control device according to claim 6 , wherein:

the predetermined action includes an action of driving a motor, and

the processor controls to limit the predetermined action by controlling so as not to perform the action of driving the motor.

8 . The control device according to claim 6 , wherein the processor estimates the amount of electric power based on an elapsed time from an end of an action other than the predetermined action.

9 . The control device according to claim 1 , wherein:

the predetermined action includes an action of driving a motor, and

the processor controls to limit the predetermined action by controlling so as not to perform the action of driving the motor.

10 . The control device according to claim 9 , wherein the processor estimates the amount of electric power based on an elapsed time from an end of an action other than the predetermined action.

11 . The control device according to claim 1 , wherein the processor estimates the amount of electric power based on an elapsed time from an end of an action other than the predetermined action.

12 . The control device according to claim 1 , wherein a charging method of the secondary battery is a CCCV method, and the predetermined charge state is a state of being charged by constant voltage.

13 . The control device according to claim 1 , wherein the predetermined charge state is a state in which charge current is less than or equal to a predetermined value.

14 . A control method comprising:

controlling (i) an electric power supply to an operating part, and (ii) charging and discharging of a secondary battery;

estimating an amount of electric power being supplied to each of the operating part and the secondary battery;

acquiring a charge state of the secondary battery; and

in response to determining that (i) the amount of electric power estimated in the estimating is less than an amount of electric power required for a predetermined action to be executed by the operating part, and (ii) the charge state of the secondary battery acquired in the acquiring is a predetermined charge state, controlling so as to limit the predetermined action.

15 . A non-transitory computer-readable recording medium storing a program for causing a computer to execute processes comprising:

controlling (i) an electric power supply to an operating part, and (ii) charging and discharging of a secondary battery;

estimating an amount of electric power being supplied to each of the operating part and the secondary battery;

acquiring a charge state of the secondary battery; and

in response to determining that (i) the amount of electric power estimated in the estimating is less than an amount of electric power required for a predetermined action to be executed by the operating part, and (ii) the charge state of the secondary battery acquired in the acquiring is a predetermined charge state, controlling so as to limit the predetermined action.
