Robot Controller Feedback for Confirming Control Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In factory settings with multiple robots and operation devices, operators face challenges in determining which operation device a controller is connected to, leading to potential confusion and safety risks.
Innovation Solution
A robot system that includes a receiving unit on the robot, a control apparatus for actuation, and an instruction apparatus with a reporting unit, where the instruction apparatus can confirm its control rights by reporting when it receives information from the control apparatus, allowing operators to identify the correct instruction apparatus for the robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple controllers and operation devices are mixed in one factory, then productivity is improved through automation, but confusion arises about which operation device is connected to which controller
Solution Approach 1:
The system implements feedback by having the control apparatus transmit connection status information to the operation device, and the operation device displaying this information through a reporting unit. This closed-loop feedback mechanism ensures operators always know which operation device is connected to which robot, preventing confusion in multi-device environments.
Solution Approach 2:
The control apparatus acts as an intermediary between the robot and the operation device, managing the connection status information and relaying it to the appropriate operation device. This intermediary role ensures accurate information transmission without requiring direct complex communication between multiple operation devices and the robot.
2Reliability
If connection confirmation is implemented through controller reporting, then connection status can be verified, but operators near the robot still cannot confirm which operation device the controller is connected to
Solution Approach 1:
The solution moves the information display from the controller dimension to the operation device dimension. Instead of the controller reporting to a central system, the connection status is directly displayed on the operation device itself, making the information immediately accessible to the operator at the point of interaction.
Solution Approach 2:
The operation device performs self-service by autonomously displaying its own connection status information. When the control apparatus transmits the connection status, the operation device automatically processes and displays this information without requiring additional manual verification steps from the operator.
3Ease of operation
If operation devices are made portable and wirelessly connected, then ease of operation is improved, but connection confusion increases among multiple devices
Solution Approach 1:
The system uses visual indicators (such as display messages or indicator lights) on the operation device to show connection status. These visual changes provide immediate, intuitive feedback about which operation device is connected to the robot, making the invisible wireless connection visible and distinguishable to operators.

AI summary
A robot system includes a robot including a robot main body having a receiving unit that receives a predetermined operation, a control apparatus that controls actuation of the robot main body, and a transmitting unit that, when the receiving unit receives the operation, transmits information representing reception of the operation, and an instruction apparatus having a receiving unit that receives the information transmitted by the transmitting unit and a first reporting unit, and instructing the control apparatus to execute an operation program, wherein, when the instruction apparatus is in a condition with a right for control in which the instruction apparatus can instruct the control apparatus to execute the operation program, when the receiving unit receives the information, the first reporting unit reports that the instruction apparatus is in the condition with the right for control.
