Mobile Robot Speed Limit Control Using Position and Condition Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile robot control systems lack effective mechanisms to dynamically adjust speed limits based on real-time position, condition, and environmental information, potentially leading to unsafe operations.
Innovation Solution
A method and apparatus that acquire position and condition information of a mobile robot, determine speed limit values using predefined models, and send start commands with speed limits to control the robot's movement, with real-time adjustments for safety, including warnings or speed reductions if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile robot automatically determines motion speed based on on-site conditions, then the robot can adapt to environmental changes, but the safety control and speed limit enforcement become insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the control server receives position information and condition information from the mobile robot, determines appropriate speed limit values based on this data, and sends control commands back to the robot. This closed-loop feedback system ensures that speed limits are dynamically adjusted according to real-time conditions while maintaining safety enforcement through centralized control.
Solution Approach 2:
The patent introduces a control server as an intermediary between the mobile robot and the environment. The server acts as a mediator that receives condition information from the robot, processes this information against predefined rules and models, and generates appropriate speed limit commands. This intermediary layer separates the adaptability function (robot collecting data) from the safety control function (server enforcing speed limits).
2Ease of operation
If the mobile robot autonomously controls its speed based on pre-programmed procedures, then the operation is simple, but the system lacks dynamic adjustment capability for changing conditions
Solution Approach 1:
The mobile robot autonomously collects its own position information and condition information, and sends this data to the control server without requiring manual intervention. The robot self-services by automatically monitoring its own state and environmental conditions, then requesting speed limit determinations from the server, maintaining operational simplicity while enabling dynamic adjustment.
Solution Approach 2:
The system transitions from static pre-programmed speed control to dynamic speed limit adjustment. The control server continuously receives updated position and condition information from the robot, processes this changing data through speed limit determination models, and dynamically adjusts speed limit values in real-time based on current conditions rather than relying on fixed pre-programmed procedures.

AI summary
A method and an apparatus for controlling a mobile robot, and a control system are provided. The method includes: in response to receiving a start request sent by a mobile robot, obtaining at least one of the position information or condition information of the mobile robot; determining a speed limit value of the mobile robot according to the obtained information; and sending a start instruction including the speed limit value to the mobile robot, so as to control the mobile robot to move at a speed smaller than or equal to the speed limit value. The implementation improves the motion safety of a mobile robot.
