First Claim
Patent Images
1. A power supply control device for a mobile robot system with a travel mechanism and a battery, comprising:
- a charging/discharging circuit electrically controlling charge and discharge of the battery;
a control circuit checking remaining power in the battery, when the control circuit determines that the remaining power is insufficient, prohibiting an operation of the travel mechanism, issuing an alarm indicating an insufficient remaining power and instructing the charging/discharging circuit to charge the battery, and when the control circuit determines that the remaining power is sufficient, permitting the operation of the travel mechanism; and
a computer executing a program controlling a series of robot system operations, and on receipt of the alarm from the control circuit, issuing a charge request message to a user.

Abstract
A charging/discharging circuit electrically controls the charge of a battery using supplied current and discharge of it. A micro-controller drives a robot according to instructions from a personal computer, controls the charging/discharging circuit while monitoring the battery state, and during the charge, prohibits the operation of a travel mechanism.
