Robot Teaching Interface for In-Path Command Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot teaching apparatuses face challenges in simplifying the process of teaching complex motion programs to lead-through teachable robots, as they lack the ability to easily set and input various commands such as movement-trajectory defining, standby, speed-changing, and work-condition changing commands at arbitrary positions on the robot's movement pathway.
Innovation Solution
A robot teaching apparatus is designed with a movement-instruction input portion and a touchscreen-type command input portion that allows for the input of movement-trajectory defining, standby, speed-changing, and work-condition changing commands at arbitrary positions on the robot's pathway, enabling the teaching of complicated motion programs in a straightforward manner. The command input portion displays input buttons that change based on the step of the teaching process, allowing for the setting of multiple commands without increasing the size of the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple commands (movement-trajectory defining, standby, speed-changing, work-condition changing) are provided through separate input mechanisms, then the robot can execute complex motion programs, but the device size and complexity increase
Solution Approach 1:
The push button is designed to perform multiple functions: it can define movement trajectories, set standby commands, change speed, and modify work conditions. By making a single input component universal, the system avoids needing separate mechanisms for each command type, thus reducing device complexity while maintaining full command input capability
Solution Approach 2:
The patent combines multiple command input functions into a single integrated push button interface. Instead of having separate controls for trajectory definition, standby, speed, and work conditions, all these functions are merged into one unified input mechanism that the operator can manipulate to set various commands at arbitrary positions on the movement pathway
2Device complexity
If a touchscreen interface dynamically changes display details based on teaching steps, then the command input portion size is reduced, but the ease of operation may be compromised
Solution Approach 1:
The touchscreen interface dynamically changes its display content based on the current teaching step and context. The display details are adjusted in real-time to show only the relevant input options and commands for the current stage of teaching, making the interface adaptive rather than static. This reduces the amount of information displayed at any given moment, effectively reducing the required display area while maintaining ease of operation through context-relevant information presentation
3Adaptability or versatility
If all commands can be set at any position on the movement pathway, then the teaching flexibility is improved, but the difficulty of detecting and measuring the teaching state increases
Solution Approach 1:
The system provides feedback to the operator about the current teaching state and the position on the movement pathway where commands are being set. The touchscreen display shows the current position, allows selection of arbitrary positions for command insertion, and provides visual confirmation of the teaching state. This feedback mechanism makes it easy to detect and measure the teaching state even though commands can be set at any position, thereby maintaining teaching flexibility without increasing difficulty

AI summary
A complicated motion program is taught, in a simple manner, to a lead-through teachable robot. Provided is a teaching apparatus for a robot, the teaching apparatus being provided with: a movement-instruction input portion that is attached to the robot and with which a movement instruction for the robot is input; and a command input portion with which it is possible to set at least one of a movement-trajectory defining command, a standby command, a speed-changing command, and a work-condition changing command at an arbitrary position on a movement pathway of the robot in a direction that corresponds to the movement instruction input via the movement-instruction input portion.
