Robot Remote Control With Haptic Feedback for Contact Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for robots rely on image quality for status checking, which can lead to delays and inaccuracies due to time lags, affecting the user's ability to accurately determine the robot's status.
Innovation Solution
Incorporating a haptic stimulator that applies stimuli to the user's sense of touch, allowing for real-time feedback on the robot's interactions with objects, complementing visual feedback from a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image quality is improved to enhance checking accuracy, then measurement precision is improved, but time lag increases causing loss of time
Solution Approach 1:
The patent divides the feedback mechanism into two separate channels: visual feedback through image display and tactile feedback through haptic stimulation. This segmentation allows the system to provide accurate status information through touch feedback without requiring high-quality real-time images, thus resolving the contradiction between checking accuracy and time lag.
Solution Approach 2:
The haptic stimulator acts as an intermediary device that converts robot status information into tactile sensations for the operator. This intermediary mechanism provides immediate feedback about robot contacts and status without relying on visual image quality, eliminating the time lag associated with high-resolution image transmission and display.
2Reliability
If image quality is improved to enhance checking accuracy, then reliability is improved, but device complexity increases
Solution Approach 1:
The system segments the feedback function into visual and tactile components, with the haptic stimulator handling critical status feedback independently. This reduces the burden on the visual display system and allows for simpler overall system architecture while maintaining or improving reliability through redundant feedback channels.
Solution Approach 2:
The patent replaces part of the visual feedback mechanism with a haptic feedback mechanism. Instead of relying solely on complex high-quality image processing and display systems, the system uses simpler haptic actuators to convey critical status information, thereby reducing device complexity while enhancing reliability.
Data Source
AI summary
A remote control system includes a robot, an operator that receives input from a user, a display that presents an image of the robot to the user, a haptic stimulator that applies a stimulus to a user's sense of touch, and a controller that controls the robot based on the input to the operator. The controller operates the haptic stimulator if the robot contacts another object.
