Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot teaching systems lack the ability for users to instantly react to the robot's situation due to the absence of real-time feedback, leading to potential accidents during operation.
Innovation Solution
A robot teaching system that incorporates a haptic device connected to a force sensor, allowing the force sensor to capture and output feedback data to the haptic device, providing tactile feedback to the user, enabling immediate situational awareness and reaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional teaching device is used to control the robot, then the robot can move according to the teaching track, but the user cannot understand the current situation of the robot in real-time
Solution Approach 1:
The patent implements a feedback mechanism where a force sensor captures feedback data from the robot's motion and rotation, converts it to a feedback signal, and transmits it to a haptic device. This allows the user to receive real-time tactile feedback about the robot's situation, enabling immediate reaction to any accidents or abnormal conditions, thus resolving the information loss problem while improving safety
2Ease of operation
If no feedback mechanism is provided, then the system remains simple, but the user cannot react immediately to the robot's situation
Solution Approach 1:
The patent introduces a haptic device as an intermediary between the robot and the user. The haptic device receives feedback signals from the force sensor and converts them into tactile sensations that the user can perceive. This intermediary mechanism enhances user control and situational awareness without requiring direct complex integration of the force sensor into the control interface, thus improving ease of operation while managing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows users to intuitively control robots in multiple degrees of freedom, reducing the risk of accidents by providing real-time tactile feedback, improving safety and efficiency during robot operation.
Implementation Method 1
the force sensor is configured to capture first feedback data corresponding to the motion and rotation of the robot according to each piece of the teaching data, and output a feedback signal, which corresponds to the first feedback data, to the haptic device
Implementation Method 2
the haptic device is configured to generate and output the pieces of teaching data to the robot, to enable the robot to move and rotate according to each piece of the teaching data
Data Source
AI summary
A robot teaching system and control method thereof are disclosed. In robot teaching system, a haptic device generates pieces of teaching data to a robot, so that the robot moves and rotates according to the pieces of teaching data, and a force sensor captures first feedback data corresponding to the motion and rotation of the robot and outputs a feedback signal, which corresponds to the first feedback data, to the haptic device. Thus, the user, who controls the haptic device, can understand the situation of the robot and react to the situation immediately, so as to avoid the risk for lack of user's instant reaction to the situation of the robot in the conventional robot teaching system.
