Abstract

A mobile work robot includes a running unit for movement, a working unit, a control unit controlling various portions of the mobile work robot with a provided instruction signal, an operation switch unit externally operated to provide the instruction signal for controlling an operation of the mobile work robot to the control unit; and a main battery supplying an electric power to the various portions of the mobile work robot. The control unit does not accept the provided instruction signal during the charging state when it is detected from a signal of a power supply connector that an AC adapter of the main battery is connected to achieve the charging state.

Claims

1. A mobile work robot comprising:

a running unit for movement;

a working unit;

a control unit accepting a instruction signal and controlling various portions of said mobile work robot with the accepted instruction signal;

an operation unit externally operated to provide said instruction signal for controlling an operation of said mobile work robot to said control unit; and

a battery supplying an electric power to the various portions of said mobile work robot, wherein

said control unit does not accept said instruction signal while said battery is in a charging state.

2. The mobile work robot according to claim 1, wherein

said control unit includes state determining means for determining whether said battery is in said charging state or not.

3. The mobile work robot according to claim 2, further comprising:

charge detecting means for detecting a connection of said battery to a charging unit prepared in advance, and outputting a detection signal, and

said state determining means determines whether said charging state is currently achieved or not, based on said detection signal received from said charge detecting means.

4. The mobile work robot according to claim 3, further comprising:

means for notifying that said charging state is currently achieved.

5. The mobile work robot according to claim 2, wherein

said state determining means determines whether said charging state is currently achieved or not, based on a remaining amount of power of said battery.

6. The mobile work robot according to claim 5, further comprising:

means for notifying that said charging state is currently achieved.

7. The mobile work robot according to claim 2, further comprising:

means for notifying that said charging state is currently achieved.

8. The mobile work robot according to claim 1, further comprising:

means for notifying that said charging state is currently achieved.
