Teach Pendant Camera for Robot Position Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in unlit industrial environments face heavy burdens when correcting robot machining positions and operation paths, as they must visually check and input commands, which is time-consuming and inefficient, especially when the machining position is hard to reach visually.
Innovation Solution
A teach pendant with an operation unit and display on one surface and a camera on the opposite surface, allowing captured images to be displayed, enabling operators to check and correct robot positions and paths more efficiently by viewing images on the display rather than relying solely on visual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators visually check machining positions and operation paths in unlighted dark environments, then they can ensure accuracy of robot operations, but operator burden increases and operation time lengthens
Solution Approach 1:
A camera is introduced as an intermediary device to capture images of the machining position and operation path. The camera transmits these images to a display unit, allowing operators to view the work area without direct visual inspection. This intermediary system enables accurate monitoring in dark environments without increasing operator burden or operation time.
Solution Approach 2:
The camera creates a visual copy (image) of the actual machining position and operation path. Instead of directly observing the physical workspace, operators view the copied visual information displayed on the display unit. This copying mechanism allows accurate assessment of machining positions without requiring operators to physically approach or visually inspect hard-to-reach areas.
2Measurement precision
If operators visually check hard-to-reach machining positions, then they can verify robot operation accuracy, but operator burden increases due to difficult access
Solution Approach 1:
The camera serves as an intermediary that reaches hard-to-access machining positions and transmits visual information to the display unit. Operators can verify machining accuracy at difficult-to-reach locations by viewing the captured images without physically approaching these areas, significantly reducing operator burden while maintaining verification accuracy.
Solution Approach 2:
The camera creates visual copies of hard-to-reach machining positions and displays them on the display unit. This allows operators to inspect and verify robot operation accuracy at locations that would be difficult or impossible to observe directly, eliminating the need for operators to physically access these areas and thereby reducing operational burden.
3Device complexity
If operators use teach pendants in dark environments without visual assistance, then they can maintain simple device structure, but they cannot effectively check machining positions
Solution Approach 1:
A camera and display unit are added as intermediary components to the teach pendant system. The camera captures visual information from the machining area and transmits it to the display unit, which presents this information to the operator. This intermediary system compensates for the lack of ambient light in dark environments, providing necessary visual information without fundamentally altering the core teach pendant functionality.
Solution Approach 2:
The camera creates visual copies of the machining position and operation path, which are then displayed on the display unit integrated with the teach pendant. This copying mechanism provides operators with visual information about machining positions in dark environments where direct observation is impossible, effectively compensating for the loss of visual information while maintaining relatively simple device structure.

AI summary
A teach pendant for teaching a robot includes an operation unit disposed on a first surface of the teach pendant, to perform an input operation; a display unit disposed on the first surface; and a camera disposed on a second surface opposite the first surface of the teach pendant. An image captured by the camera is displayed on the display unit.
