Automatic Machine Motion Control with Dynamic Time Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robots execute motions in a preset template format, leading to unsmooth transitions between predefined motions, causing discomfort due to the inability to seamlessly execute varied motion patterns.
Innovation Solution
An automatic machine comprising an output unit, storage unit, and control unit that reads motion patterns stored with predetermined information and time tags, calculates time adjustments, and controls the output unit to smoothly transition between motion frames, ensuring seamless execution of motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motions are executed according to preset templates, then motion execution is simple and controllable, but motion transitions become unsmooth and rigid
Solution Approach 1:
The patent applies dynamics by making the motion template adjustable and adaptable during execution. The control unit modifies motion parameters in real-time based on actual robot state and environment, transforming rigid preset templates into dynamic adaptable motion patterns that ensure smooth transitions while maintaining execution simplicity
Solution Approach 2:
The patent changes motion parameters dynamically during execution. The control unit adjusts velocity, acceleration, and timing parameters based on real-time feedback and pre-stored motion patterns, allowing the robot to transition smoothly between motions while still following the structured template framework
2Stability of the object's composition
If motion templates are executed in sequence, then motion execution is orderly and predictable, but transitions between different templates cannot be seamless
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple motion patterns and transition strategies in advance. The control unit selects and prepares appropriate motion patterns before execution, ensuring that seamless transitions are already planned and ready, thus maintaining execution order while eliminating unsmooth transitions
Solution Approach 2:
The patent uses feedback mechanisms where the control unit continuously monitors the robot's actual motion state and compares it with the expected state from motion templates. Based on this feedback, the control unit dynamically adjusts parameters to ensure seamless transitions while maintaining the overall orderly execution sequence

AI summary
An automatic machine includes an output unit, a storage unit and a control unit. The storage unit stores a motion pattern corresponding to a command and recording N predetermined motion information and N time tags. The control unit receives the command, reads a current motion information of the output unit, looks the motion pattern up in the storage unit according to the command and the current motion information, determines that the current motion information is between the i-th predetermined motion information and the (i+1)-th predetermined motion information, calculating a time adjusting information by the (i+1)-th predetermined motion information, the (i+1)-th time tag and the current motion information, and controls the output unit to execute the (i+1)-th predetermined motion information according to the current motion information, the first time tag through the i-th time tag, and the time adjusting information.
