Solution Overview
Problem
In warehousing and logistics systems, the proximity of robots and users near temporary storage shelving units poses a safety risk due to potential collisions, leading to personal injury and poor safety.
Innovation Solution
A robot control method and system that determines the storage position of a user's operation and controls the robot to avoid performing operations at the same position simultaneously, using detection devices like pressure sensors, laser radar, infrared sensors, or visual acquisition devices to identify user presence and proximity, and adjusting robot operations to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot performs operations near the temporary storage shelving unit to improve goods sorting efficiency, then productivity is improved, but the robot may come into contact with the user causing safety issues
Solution Approach 1:
A detection device is introduced as an intermediary between the robot and the user to monitor the user's presence and operation status. The detection device acquires detection information about the user's position and arm movements, and the control device uses this information to control the robot's operations, preventing direct contact while maintaining efficient goods sorting processes
Solution Approach 2:
The system implements a feedback mechanism where the detection device continuously monitors the user's position and operation status, sends detection information to the control device, which then adjusts the robot's operations in real-time based on this feedback. This closed-loop control ensures the robot stops or avoids operations when the user is present, maintaining safety without significantly reducing productivity
2Reliability
If the robot is controlled to avoid operations at the same position as the user to improve safety, then reliability is improved, but the robot cannot perform operations efficiently
Solution Approach 1:
The robot's operation status is made dynamic rather than static. The control device adjusts the robot's operations in real-time based on the user's presence and detection information. When the user is not present, the robot operates efficiently; when the user is detected, the robot dynamically adjusts its operations to avoid contact, thus maintaining both safety and efficiency
Solution Approach 2:
The detection device acquires detection information about the user's position and operation status before the robot performs operations. This preliminary detection allows the control device to plan and execute robot operations that avoid user presence from the outset, preventing safety issues while maintaining operational efficiency
