Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control methods for mobile robots, such as those using multiple buttons or touchpads, are inconvenient for users, particularly when setting reservations, as they require repetitive button presses and are prone to errors, leading to user inconvenience and increased complexity.
Innovation Solution
A mobile robot system utilizing a jog-dial interface with light emitting units that transmit control commands through shuttling rotation direction, angular speed, and angle information, allowing intuitive input for movement and operation commands, including time and reservation settings, and direct control modes, with buttons for power, charging, and mode control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional remote control interface with multiple buttons or touchpad is used, then the mobile robot can be controlled, but the user input process becomes complex and inconvenient requiring repetitive button presses
Solution Approach 1:
The dial interface is segmented into distinct operational modes (reservation mode, direct control mode, time setting mode) that can be independently selected and operated. Each mode handles specific control tasks, dividing the complex control interface into manageable segments that reduce overall operational complexity
Solution Approach 2:
The single dial interface serves multiple functions across different modes: it can set reservation times, control robot movement direction, adjust rotation speed, and configure operational parameters. This multi-functional design replaces the need for multiple specialized buttons and controls, simplifying the interface while maintaining comprehensive control capability
2Productivity
If conventional button-based interface is used for reservation setting, then the function can be implemented, but the number of操作步骤 increases requiring at least ten button presses
Solution Approach 1:
The system enters a reservation mode where the dial is pre-configured to accept time and date inputs directly. Users can preliminarily set the desired reservation parameters by simply rotating the dial to the target position, which the system then automatically processes as a complete reservation command, eliminating the need for multiple sequential button presses
Solution Approach 2:
The dial interface allows users to skip intermediate steps in the reservation process by directly rotating to the desired time and date configuration. The system interprets the final dial position as the complete reservation intent, rushing through multiple traditional input steps into a single intuitive action
3Reliability
If conventional button interface is used, then control functions can be accessed, but input errors increase and require returning to initial process
Solution Approach 1:
The system provides visual feedback through a display unit that shows the current dial position and corresponding command interpretation in real-time. This feedback mechanism allows users to verify their input before execution, reducing errors by enabling correction of misaligned dial positions without requiring a complete restart of the input process
4Ease of operation
If jog-dial interface with light emitting units is used, then user input becomes intuitive and efficient, but the device structure becomes more complex
Solution Approach 1:
Light emitting units arranged in the inner circumference of the dial change color or illuminate to indicate different operational states, selected modes, and input validation status. This visual coding system provides intuitive feedback that enhances ease of operation by making system state immediately recognizable without requiring complex displays or multiple indicators

Implementation Method 1
A plurality of light emitting units arranged in an inner circumference of the dial, wherein the plurality of light emitting units display user input information changed according to shuttling of the dial in the first rotation direction or the second rotation direction

AI summary
A mobile robot system for allowing a user to easily input a control command of a mobile robot, and a remote control method for the same are disclosed. The mobile robot system and the remote control method thereof can allow a user to easily input control commands regarding the movement and operation of the mobile robot using the jog-dial interface, such that the possibility of causing input errors can be reduced and desired commands can be quickly and efficiently transmitted, resulting in increased user manipulation of the mobile robot system. When the user enters the rotation command of the mobile robot, the mobile robot system can allow the user to perform intuitive interfacing through shuttle manipulation, such that the mobile robot system can facilitate transmission of a movement command having a circular trajectory and the same mobile robot control as in the user-intended control is achieved, resulting in implementation of emotional interface capable of increasing user accessibility.
