Amusement Ride Robot Arm Controller with Dynamic Motion Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing amusement rides lack effective safety measures to ensure safe operation and passenger safety during movement, particularly in determining and maintaining maximum allowable motion components within defined working spaces.
Innovation Solution
A robot system with multi-link robot arms and a controller that determines and reduces motion components based on the distance from working space limits, using positioning and safety means to ensure safe operation by adjusting motion components in real-time, and switching between manual and automatic modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot system operates with high speed and large motion components, then productivity and amusement value are improved, but safety risks increase when approaching working space limits
Solution Approach 1:
The controller continuously determines the distance between the passenger holder and the working space arrangement limit during operation, and dynamically adjusts motion components based on this feedback. When the distance decreases, the controller reduces velocity and acceleration components to prevent collisions, while allowing higher speeds when sufficient distance is maintained.
Solution Approach 2:
The system dynamically adjusts motion parameters (velocity, acceleration) based on real-time distance measurements. The motion components are not fixed but adapt continuously to the current position relative to working space limits, enabling high performance when safe and restrictive measures when approaching boundaries.
2Reliability
If the controller continuously monitors and adjusts motion components to maintain safety distances, then safety is improved, but device complexity increases
Solution Approach 1:
The controller performs multiple functions: it controls the robot arm motion, determines position, calculates distance to working space limits, and adjusts motion components. By consolidating these functions in a single controller rather than using separate dedicated devices, the system achieves high safety functionality without proportionally increasing overall device complexity.

AI summary
An amusement ride includes a robot assembly having at least one multi-link robot arm with a base and a passenger holder for transporting at least one person. A controller for controlling the robot assembly includes a storage device for storing a limit of a working space arrangement having at least one work space, a distance device for determining a distance of the passenger holder from the working space arrangement, and a safety device for determining maximum permissible motion components in at least two spatial directions depending on the determined distance.
