Solution Overview
Problem
Existing mobile devices for disinfecting indoor areas lack the capability to safely operate without human intervention, as they do not have remote control functionality to ensure safety and efficiency in disinfecting while avoiding human presence.
Innovation Solution
A mobile robot equipped with a UV light source, sensors, and a communications interface that allows remote operation via a second controller, which can detect human presence and control the UV light output to prevent harm and ensure effective disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices are used for disinfection without remote control capability, then the device can operate autonomously in the area, but it cannot ensure safety by preventing UV light exposure to humans
Solution Approach 1:
A remote controller is introduced as an intermediary device that allows operators to control the mobile disinfection device from a safe distance. The remote controller receives operator inputs and transmits control signals to the mobile device, enabling safe operation in environments where direct human presence would be hazardous due to UV light exposure.
Solution Approach 2:
The control system is segmented into two separate components: the mobile disinfection device itself and a separate remote controller. This segmentation allows the control functions to be separated from the execution functions, enabling operators to remain outside the hazardous area while maintaining control over the disinfection process.
2Productivity
If UV light is applied continuously for effective disinfection, then the disinfection efficiency is improved, but it creates harmful effects if humans are present in the area
Solution Approach 1:
The remote controller serves as an intermediary that enables the operator to initiate and control continuous UV light operation without being physically present in the disinfection area. This allows the system to maintain high disinfection efficiency while eliminating direct human exposure to harmful UV radiation.
Solution Approach 2:
The system replaces the need for manual monitoring and physical presence during UV operation with automated control mechanisms. The remote controller with its interface and communication system substitutes for direct human oversight, allowing continuous operation to proceed safely without mechanical intervention in the hazardous zone.
3Adaptability or versatility
If the mobile robot operates without remote control capability, then the operation is simpler, but it cannot receive real-time control signals to adjust operation based on human presence detection
Solution Approach 1:
The remote controller is designed as a universal control interface that can handle multiple functions: initiating disinfection cycles, monitoring operational status, and responding to human presence detection. This multi-functional design allows a single device to provide comprehensive control capabilities without requiring multiple separate systems.
Solution Approach 2:
The system incorporates feedback mechanisms where the mobile device detects human presence and communicates this information to the remote controller. The remote controller then adjusts operational parameters or alerts the operator, creating a closed-loop control system that adapts to changing conditions while maintaining manageable complexity through the remote interface.

AI summary
Implementations of the disclosed subject matter provide a mobile robot including a motor to drive a drive system to move the mobile robot in an area, a light source to output ultraviolet (UV) light, at least one sensor, a communications interface to receive at least one signal via a communications network, and a first controller to control the drive system, the light source, the at least one sensor, and the communications interface. Operations of the mobile robot may be controlled based in part on the at least one signal received via the communications network from a second controller that is in a location that is remote from the area where the mobile robot is operating.
