Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial robot systems with touch panel pendants, operators face challenges with finger instability on the touch panel, leading to unintended axis operations during teaching and manipulation, affecting operability and work efficiency.
Innovation Solution
A robot operating apparatus with a touch panel that sets a coordinate system and determination area, allowing selection of robot axes based on touch operation direction and providing an operating area with a predetermined width to prevent erroneous operations, ensuring accurate axis selection and mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If touch operations are used on the touch panel, then the device size is reduced and display screen is enlarged, but finger instability causes unintended axis operations
Solution Approach 1:
The touch panel is divided into multiple determination areas, each corresponding to a specific robot axis. When the operator touches a specific area, only the corresponding axis is activated for operation. This segmentation prevents unintended axis operations by spatially separating the control functions on the touch panel.
Solution Approach 2:
The determination area acts as an intermediary between the operator's touch input and the robot axis selection. By requiring the touch to occur within a specific determination area, the system mediates the operation to ensure the intended axis is selected, reducing errors from finger instability.
2Productivity
If concurrent operation of multiple axes is enabled, then maneuverability is improved and teaching time is shortened, but finger deviation causes mode switching difficulties
Solution Approach 1:
The touch panel is segmented into determination areas for single-axis mode and two-axis mode operations. By touching different areas, the operator can select the desired operation mode without complex switching procedures. This maintains high teaching efficiency while simplifying mode selection.
Solution Approach 2:
The system preliminarily sets multiple determination areas that correspond to different operation modes before the operator performs teaching. The operator can directly touch the appropriate determination area to activate the desired mode, eliminating the need for sequential mode switching during teaching operations.
3Measurement precision
If frequent mode switching is required, then accurate single-axis operation is achieved, but work efficiency decreases
Solution Approach 1:
The touch panel is divided into determination areas that allow direct selection of operation modes. The operator can touch the appropriate determination area to switch between single-axis and two-axis modes without complex procedures, maintaining positioning accuracy while improving work efficiency.
Solution Approach 2:
The operation mode is made dynamic and adjustable through simple touch operations on the touch panel. The system can switch between single-axis and two-axis modes based on the teaching requirements, allowing the operator to optimize for either precision or speed as needed without frequent complex mode changes.

AI summary
A pendant provided with a touch panel is provided as a robot operating apparatus. Using the pendant, an operating position of, for example, an operator's touch operation on the touch panel is detected. In the pendant, by calculation responding to the touch operation, a coordinate system having axes is set on the touch panel in response to the touch operation, in which the axes are associated with the axes of a robot. A determination area is also set on the touch panel in the periphery of a start position of the touch operation. The determination area has a predetermined size. In the pendant, an axis being operated of the robot is selected based on an arrival position of the touch operation in the determination area. An operating area on the touch panel is set with the arrival position as the center of the determination area, ensuring a highly-reliable touch operation.
