Teaching Manager

Teaching Manager provides a graphical interface for teaching robot positions and managing numbered position variables (P variables). Its primary purpose is to manage robot coordinates outside the robot's internal variable memory, using local data and JSON files. This allows position data to be maintained independently of the robot controller's built-in P-variable storage.

The software reads the robot's current position through a connected device interface, assigns that position to a selected P number, and stores the resulting position table. A RobotVarManager class also provides a Python interface for managing cached variables, loading and saving JSON, and explicitly transferring variables to or from a connected robot.

Storage behavior

The implementation supports two storage modes selected by the device name:

Devices other than CobottaCtrl: P variables are managed in JSON rather than in the robot's internal variable memory. Teaching, clearing, and deleting entries update the JSON data.
CobottaCtrl: the application uses the robot's internal P variables. Explicit teaching or clearing writes to the robot and reads the result back. JSON export is available separately.

This distinction matters: external coordinate management is the primary use case, but the existing code retains a robot-memory mode for CobottaCtrl.

Main functions

Acquire the current robot position and associate it with a specified P number.
Display and manage numbered positions in a Qt-based GUI.
Load and save position tables as JSON files.
Clear or delete selected positions, with behavior determined by storage mode.
Manage variables programmatically using RobotVarManager.

Operational notes

Teaching to a specified number can overwrite its existing value. The automatic “first unused P number” feature is disabled because the implementation does not yet define a reliable unused-number criterion. Reading the current position does not itself write to robot memory or JSON.
