Industrial Robot Programming via Data Carrier Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing programming methods for industrial robots lack safety measures to prevent unintentional activation of automatic mode, which can lead to accidents during programming and operation.
Innovation Solution
A handheld programming device that requires a data carrier to be operatively coupled to the machine's interface to enable automatic mode, ensuring the machine remains in manual mode unless the carrier is present, and uses a personalized data carrier to authorize specific functions and log user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the machine can be operated in automatic mode without restrictions, then productivity is improved, but safety deteriorates due to risk of unintentional activation during programming
Solution Approach 1:
A data carrier serves as an intermediary between the programming device and the machine's control system. The data carrier must be present in the machine to enable automatic mode, while simultaneously being readable by the programming device to authorize programming operations. This intermediary mechanism ensures that automatic mode cannot be activated unintentionally during programming, as the programming device verifies the data carrier's presence and contents before allowing programming functions.
2Reliability
If safety measures are implemented to prevent unintentional automatic mode activation, then reliability is improved, but device complexity worsens due to additional data carrier requirements
Solution Approach 1:
The data carrier is designed to serve multiple functions simultaneously: it acts as an authorization key for programming operations, enables automatic mode activation in the machine, and provides identification for the programming device. By consolidating these functions into a single data carrier, the system achieves enhanced safety without proportionally increasing complexity, as the same physical object fulfills multiple security and operational roles.
3Ease of operation
If the programming device can operate without authorization verification, then ease of operation is improved, but reliability worsens due to lack of user action logging and authorization
Solution Approach 1:
The programming device automatically performs authorization verification by reading the data carrier and logging user actions without requiring manual intervention. The system self-verifies the operator's authority through the data carrier contents and automatically records programming operations, maintaining ease of operation while ensuring reliability through automated authorization and logging functions.

AI summary
The invention relates to a programmable machine, in particular an industrial robot (1, R1, R2), a programming handheld device (PHG), and a method for programming a programmable machine (1, R1, R2). The machine (1, R1, R2) comprises at least one axis (A, B, A1-A6), a control computer (8, S1, S2) for controlling the axis (A, B, A1-A6), a first data carrier (13) associated with the machine (1, R1, R2), and a first interface (12) for reading the first data carrier (13). The machine (1, R1, R2) can be operated in manual mode, in which the machine (1, R1, R2) can be programmed and/or controlled by means of a programming handheld device (PHG), and in automatic mode, in which the control computer (8, S1, S2) automatically controls the axis (A, B, A1-A6). The machine (1, R1, R2) can only be operated in its automatic mode if the first data carrier (13) is operationally coupled with the first interface (12).
