Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require expensive and complex equipment for machines to accurately identify their positions, leading to increased costs and inefficiencies in task execution.
Innovation Solution
An autonomous working system comprising a master working robot and at least one slave working robot, where the master robot determines its position using sensing data and reference map data, and the slave robot determines its position relative to the master robot, allowing for accurate task execution with a simple configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive equipment with high complexity is used for position identification, then measurement precision is improved, but device complexity increases and costs increase
Solution Approach 1:
The patent introduces a master robot as an intermediary that performs position identification and communicates position information to slave robots. Instead of each robot having complex expensive positioning equipment, the master robot acts as a mediator that simplifies the positioning system while maintaining accuracy through relative position measurements.
Solution Approach 2:
The slave robots determine their positions by copying or referencing the master robot's position information and adding relative position offsets. This allows slave robots to achieve accurate positioning without duplicating the full positioning capability of the master, reducing overall system complexity and cost.
2Productivity
If more equipment is used to quickly perform various tasks, then productivity is improved, but costs increase due to expensive equipment
Solution Approach 1:
The patent divides the robot system into a master robot that handles complex positioning functions and slave robots that handle task execution. This segmentation allows the system to achieve high productivity through multiple robots while avoiding the need for each robot to have expensive positioning equipment, as only the master robot requires full positioning capability.
3Device complexity
If a simple system configuration is used, then device complexity is reduced, but measurement precision of position determination deteriorates
Solution Approach 1:
The system uses feedback by continuously measuring relative positions between master and slave robots and using this information to calculate absolute positions. The master robot determines its position through sensing data and reference map data, then slave robots use this feedback along with their relative position measurements to determine their own positions accurately despite the simple system configuration.
