Service Robot Charging Interruption for Power Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service robots may remain in a halted state due to battery discharge when the charging apparatus experiences power failure or is out of order, or when a user intentionally interrupts the charging process, leading to continuous attempts to reconnect without resolution.
Innovation Solution
A method for charging a service robot that involves docking with a charging apparatus when the battery level falls below a threshold, checking for a predetermined charging voltage, and interrupting charging if power failure or the charging apparatus is out of order, using inductive signals and floor detection sensors to determine the status and prevent continuous re-attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the service robot continuously attempts to reconnect to the charging apparatus when charging fails, then the robot can potentially resume charging, but the battery will discharge and the robot will remain in a halted state
Solution Approach 1:
The controller detects whether a predetermined voltage is input to the input terminal during charging attempts. Based on this feedback, the controller determines whether to continue attempting to connect to the charging apparatus or to interrupt the charging mode and resume cleaning mode, preventing continuous battery discharge without resolution
Solution Approach 2:
The service robot autonomously monitors its own battery status and charging state, making decisions about whether to attempt reconnection or resume cleaning operations based on detected voltage levels, without requiring external intervention
2Reliability
If the service robot detects charging failure and attempts to reconnect to the charging apparatus, then charging may be resumed, but the robot wastes time wandering to locate the charging apparatus
Solution Approach 1:
The controller uses feedback from voltage detection at the input terminal to determine whether the charging apparatus is functioning properly. If no predetermined voltage is detected after connection attempts, the controller concludes the charging apparatus is out of order and stops wandering to locate it, resuming cleaning operations instead
3Stability of the object's composition
If the service robot remains in charging mode after connection failure, then the robot maintains docking position, but the robot cannot perform cleaning operations
Solution Approach 1:
The charging mode is made dynamic rather than static. The controller continuously monitors voltage input to the input terminal and can transition between charging mode and cleaning mode based on real-time conditions, allowing the robot to resume productive operations when charging is unavailable

AI summary
A method for charging a service robot is provided, which includes (a) docking an input terminal of the service robot with an output terminal of a charging apparatus, if an available battery power source falls below a predetermined level; (b) checking whether a predetermined charging voltage is input to the input terminal of the service robot; (c) determining whether power failure has occurred or the charging apparatus is out of order, if the charging voltage is not input in step (b); and (d) interrupting charging of the battery, if it is determined that power failure has occurred or the charging apparatus is out of order.
