Solution Overview
Problem
Existing robot systems face challenges in safely and efficiently transporting items between indoor and outdoor environments, particularly in delivering items from a station body to a destination while maximizing the size of items that can be stored.
Innovation Solution
A robot system comprising a station body with guide rails and robots that move in different directions, including a first robot with a lifter and a second robot with a seating body, allowing for efficient item transfer and charging mechanisms, along with a pusher and conveyor for item handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single robot moves items in one direction, then the structure is simple, but the transportation efficiency and storage capacity are limited
Solution Approach 1:
The robot system is divided into multiple independent robots (first robot with lifter, second robot with seating body) that operate on separate guide rails. Each robot handles specific transportation tasks in different directions, allowing parallel operations and improved overall productivity without requiring a single complex robot structure.
Solution Approach 2:
The system transitions from single-direction linear transportation to multi-dimensional transportation by adding robots that move in different directions (first direction and second direction perpendicular to each other) on different guide rails, enabling more efficient item routing and station utilization.
2Ease of operation
If guide rails are positioned at higher levels, then item access is easier, but the storage space within the station body is reduced
Solution Approach 1:
The system uses vertical stacking of guide rails at different heights (first guide rail at first height, second guide rail at second height lower than first) to create multi-level transportation pathways. This allows items to be accessed from multiple vertical levels simultaneously, maintaining ease of operation while maximizing the use of vertical space for storage.
Solution Approach 2:
The second robot with seating body is positioned at a lower height and can accommodate the first robot when not in use. This nested arrangement allows both robots to coexist in a compact configuration, optimizing space utilization within the station body while maintaining access to items at different heights.
3Speed
If multiple robots operate simultaneously, then transportation speed increases, but the risk of collision and system failure increases
Solution Approach 1:
The system separates multiple robots onto different guide rails (first guide rail for first robot, second guide rail for second robot) that are positioned at different heights and orientations. This spatial segmentation prevents physical collisions between robots while allowing them to operate simultaneously at high speeds, maintaining system safety through physical isolation of movement paths.

AI summary
Provided is a robot system. The robot system comprises a station body on which an object is placed; a first robot having a lifter that lifts the object placed on the station body and disposed to move in a first direction on the station body; and a second robot disposed on the station body to move in a second direction different from the first direction and having a seating body on which the first robot is seated.
