Segmented Parking Robot System for Ramp Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking robots are limited by their inability to travel quickly within multistory car parks and often struggle with ramps and steep inclines due to their design, which restricts their speed and operational range.
Innovation Solution
A parking robot system comprising a main guiding robot and multiple secondary robots, each with wheel support arms that can lift and support the transportation vehicle's wheels, allowing the system to navigate obstacles and travel at higher speeds by using a guiding robot to direct the secondary robots to a target position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional parking robots use a single-part or multi-part design positioned underneath the vehicle, then the structure is simple and easy to manufacture, but the robot cannot travel quickly and struggles with ramps and steep inclines
Solution Approach 1:
The parking robot system is divided into multiple independent robot parts, each positioned at individual wheels of the transportation vehicle. Each robot part independently supports and maneuvers one wheel, enabling the system to navigate ramps and steep inclines more effectively while maintaining travel speed capability.
Solution Approach 2:
A guiding robot is introduced as an intermediary component that travels ahead of the other robot parts and provides guidance signals. This guiding robot enables coordinated movement of multiple robot parts, allowing the system to travel quickly while maintaining precise control over complex maneuvers including ramp navigation.
2Adaptability or versatility
If the parking robot is designed to overcome ramps and steep inclines, then the operational range is improved, but the robot cannot travel quickly within the car park infrastructure
Solution Approach 1:
By segmenting the robot system into multiple independent parts positioned at different wheels, each part can independently adapt to local terrain conditions including ramps and steep inclines. This segmentation allows the system to maintain high travel speed on flat surfaces while simultaneously handling complex infrastructure levels when needed.
Solution Approach 2:
The robot parts are designed with dynamic capabilities to adjust their behavior based on terrain conditions. The guiding robot dynamically provides guidance signals that enable the system to switch between high-speed travel mode on flat surfaces and ramp-negotiation mode when encountering steep inclines, thus maintaining both speed and adaptability.
3Adaptability or versatility
If individual robot parts are arranged on individual wheels, then the ability to overcome ramps is improved, but the system complexity and coordination requirements increase
Solution Approach 1:
The guiding robot serves as an intermediary that simplifies system coordination by providing centralized guidance signals to all other robot parts. This intermediary approach enables individual robot parts to maintain independent ramp-overcoming capability while reducing the coordination complexity through a hierarchical control structure where the guiding robot makes navigation decisions.
Solution Approach 2:
Each robot part positioned at individual wheels is designed to be self-sufficient in handling its local terrain conditions, particularly for ramp negotiation. The parts autonomously execute maneuvers based on guidance signals, reducing the need for complex inter-part coordination while maintaining the ability to overcome ramps and steep inclines.

AI summary
A parking robot system for a transportation vehicle having wheels and a method for operating a parking robot system. The parking robot system includes a main robot and secondary robots and a method for operating a parking robot system. The secondary robots each have a pair of wheel support arms and each move up autonomously, with the wheel support arms folded in, from outside next to one of the wheels of the transportation vehicle. The secondary robots each lift up the respective wheel by folding out the respective pair of wheel support arms. The main robot accompanies the secondary robot with the lifted up transportation vehicle during travel to a prescribed target position.
