Solution Overview
Problem
Existing robot technologies fail to accurately determine their location when forcibly moved by a user, leading to incomplete or inappropriate service execution, as they lack effective methods to reassess tasks based on new locations and environments.
Innovation Solution
A robot equipped with a driver unit, sensor unit, and controller that uses environment information and pre-stored map data to determine its current location and adjust tasks accordingly, prioritizing tasks based on user intent, location, and environmental conditions, including dust concentration and complexity levels, and utilizing sensors like UWB for navigation and odor detection.

Engineering Contradiction Analysis
1Ease of operation
If the robot location is forcibly moved by the user, then the robot can be repositioned to a different area, but the location determination becomes inaccurate and service initialization occurs
Solution Approach 1:
The robot uses sensor units to continuously sense the environment and compare sensed features with pre-stored map information, creating a feedback loop that enables accurate location determination even after forcible movement. The controller adjusts the location estimate based on the match between sensed environment and map data.
Solution Approach 2:
The system performs preliminary mapping by storing map information about the environment before the robot is moved. This pre-stored map data serves as a reference for subsequent location determination, allowing the robot to quickly re-establish its position after being repositioned without full service initialization.
2Duration of action of stationary object
If the robot continues the existing service after forcible movement, then service continuity is maintained, but the user intention to move the robot is not reflected
Solution Approach 1:
The system dynamically adjusts service execution based on the robot's new location. The controller determines whether to continue the existing service or switch to a different service based on the matched location in the map and current environmental conditions, making the service adaptable to both continuity requirements and user repositioning intentions.
Solution Approach 2:
The system changes service parameters based on location information. When the robot is repositioned, the controller checks the new location against the map and adjusts the service type or parameters accordingly, allowing the service to adapt to the new context while maintaining operational continuity.
3Measurement precision
If the robot uses environment sensing and map matching to determine location, then location accuracy improves, but system complexity increases
Solution Approach 1:
The sensor unit serves multiple functions: it senses environmental features for location determination, detects obstacles, and monitors service conditions. This multi-functionality reduces the need for separate dedicated components, managing system complexity while maintaining accurate location determination through environment sensing and map matching.

AI summary
A robot and a controlling method thereof are provided. The robot includes a driver unit configured to move a location of the robot, a sensor unit configured to sense an environment around the robot, and a controller configured to, in response to the location of the robot being changed by a user, check a current location of the robot by using the environment of the changed location sensed by the sensor unit and pre-stored map information, determine a task to be performed, based on the checked location and the environment of the changed location, and control the driver unit according to the determined task.
