Robot Teaching Device with Removable Motion Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot teaching devices are cumbersome and restrictive, with physical limitations due to wired connections and cumbersome input interfaces, making them difficult to use for programming robot motions along fixed trajectories.
Innovation Solution
A robot teaching device with a connecting base and a removable motion device that uses wireless connectivity and a touch screen with virtual keys, allowing for remote programming and reduced user burden by switching between physical and virtual key operation based on an enable switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot teaching device is signal-connected to the robot via a transmission wire, then reliable signal transmission is achieved, but the user's motion is restricted by the length of the transmission wire
Solution Approach 1:
The teaching device is divided into two separate components: a base unit that remains connected to the robot via transmission wire, and a remote control unit that the user can move freely. This segmentation allows the user to operate the robot without being constrained by the wire length, while the base unit maintains reliable signal transmission to the robot.
Solution Approach 2:
The base unit acts as an intermediary between the robot and the remote control unit. It receives signals from the robot and transmits them to the remote control unit via wireless communication, allowing the user to control the robot from a distance without direct wired connection.
2Ease of operation
If the robot teaching device is equipped with input keys and a display screen, then teaching operations can be performed, but the size and weight of the device increase making it difficult to hold for a long time
Solution Approach 1:
The heavy components including input keys and display screen are extracted from the remote control unit and placed in the base unit. The remote control unit becomes lightweight and portable, while the base unit contains all the heavy operational components. This extraction allows users to hold and move the remote control unit easily without being burdened by weight.
Solution Approach 2:
The base unit contains a copy of the teaching interface and control functionality. The remote control unit communicates with the base unit, which provides the full teaching operations capability. This copying approach allows the remote unit to be lightweight while still providing access to complete teaching functions through the base unit.
3Ease of operation
If the touch screen displays virtual keys continuously, then user convenience is improved, but safety risk increases when user is unfamiliar with the device
Solution Approach 1:
The display of virtual keys on the touch screen is made dynamic rather than static. The virtual keys are displayed and activated only when the enable switch is pressed, and are switched off or deactivated when the enable switch is released. This dynamic control allows convenient operation when needed while preventing accidental activation when the user is unfamiliar with the device.
Solution Approach 2:
The enable switch provides tactile feedback and visual feedback (through the display state) to indicate when the device is in an active or inactive state. When the enable switch is pressed, the system provides feedback by displaying virtual keys, confirming that the device is ready for operation. When released, the feedback indicates the device is inactive, preventing unintended operations.

AI summary
A robot teaching device is suitable for being signal connected to a controller used to control a robot, and includes: a connecting base which includes an enable switch and a first connector, and is connected to the controller by a transmission wire; a motion device which is removably disposed in the connecting base, and includes a second connector connected to the first connector, and a touch screen for displaying plural virtual keys. The motion device will be wirelessly signal connected to the controller, when it is removed from the connecting base, and the touch screen will display the virtual keys. When the motion device is inserted in the connecting base, and the enable switch is not pressed, the first and second connectors will be connected, and the virtual keys will be switched off. The virtual keys will be switched on after the enable switch is kept being pressed.
