Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing input devices for industrial robots lack an intuitive and compact mechanism to control the three-dimensional movement and orientation of a robot's distal end, limiting the precision and ease of operation.
Innovation Solution
A robot control system featuring a three-dimensionally movable input device with detectors that resolve operation amounts into parallel and rotational movements along orthogonal axes, allowing for intuitive control of the robot's position and orientation by associating these movements with corresponding output values in a coordinate system at the robot's distal end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a joystick-type input device is used to control robot position and orientation, then the robot can be operated, but the device becomes bulky and complex
Solution Approach 1:
The input device is segmented into independent functional components: a base unit and a movable section that can be positioned at different locations. This segmentation allows each component to be simple in structure while collectively providing comprehensive 3D control capabilities, resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The invention transitions from traditional 2D joystick control to 3D spatial control by allowing the movable section to be positioned freely in three-dimensional space relative to the base. This dimensional expansion enables intuitive control of robot position and orientation without requiring a bulky multi-axis joystick mechanism
2Measurement precision
If traditional input devices are used to control three-dimensional movement, then basic operation is possible, but the control precision and intuitiveness are limited
Solution Approach 1:
The detector provides real-time feedback by resolving the movable section's position into parallel movement amounts along three orthogonal axes. This feedback mechanism enables precise control of robot movement while maintaining intuitive operation, as the operator can directly correlate physical positioning with digital control signals
Solution Approach 2:
The invention replaces complex mechanical control mechanisms with a detector-based system that electronically resolves position into orthogonal components. This substitution maintains high control precision while improving ease of operation through simpler, more direct manipulation of the movable section

AI summary
A compact, intuitively-operable input device for manipulating a robot is provided. Provided is an input device for manipulating a robot. The input device includes: a base; a movable section supported in a three-dimensionally movable manner relative to the base; and a detector that performs detection by resolving an operation amount of the movable section relative to the base into parallel movement amounts along a first axis and a second axis, which extend parallel to a predetermined surface of the base and are orthogonal to each other, and a parallel movement amount along a third axis that is orthogonal to the first axis and the second axis.
