Solution Overview
Problem
Existing robotic systems in transportation vehicle applications require complex and costly control hardware, which increases the acquisition cost of robots and limits their versatility in performing diverse tasks.
Innovation Solution
A transportation vehicle equipped with a controller and data interface that transmits control signals to a robot via a wireless or cable-based method, allowing decentralized robot control and eliminating the need for control hardware on the robot, while using sensors to monitor and adjust the robot's posture and position for optimal task performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If control hardware is integrated into the robot, then the robot can autonomously perform tasks, but the acquisition cost and device complexity increase significantly
Solution Approach 1:
The control hardware is extracted from the robot and relocated to the transportation vehicle. The robot retains only the minimal data interface for receiving control signals, while the controller in the transportation vehicle generates and transmits control signals to the robot, thereby reducing robot complexity while maintaining automation capability
Solution Approach 2:
The controller in the transportation vehicle serves dual functions: controlling the transportation vehicle itself and controlling the robot for specified working tasks. This multi-functionality eliminates the need for separate control hardware in the robot, reducing overall system complexity and cost
2Extent of automation
If control hardware is integrated into the robot, then the robot can independently control tasks, but the acquisition cost increases
Solution Approach 1:
The controller is extracted from the robot and placed in the transportation vehicle. The robot only requires a data interface to receive control signals, while the transportation vehicle's controller handles all control signal generation and transmission, thereby eliminating expensive control hardware from the robot
3Device complexity
If the controller is relocated to the transportation vehicle, then robot cost is reduced, but the data transmission requirement increases
Solution Approach 1:
A data interface acts as an intermediary between the transportation vehicle's controller and the robot. This interface ensures reliable bidirectional communication, transmitting control signals from the controller to the robot and status information from the robot to the controller, thereby maintaining information integrity despite the spatial separation
