6. Operating Instructions
The K96173 building block models can be controlled using either the included 2.4G remote controller or via a dedicated mobile application.
6.1 Remote Control Operation
Use the provided 2.4G remote controller to operate the assembled models. Refer to the paper manual for specific button functions and control schemes for each model.
6.2 App Control Operation
Download the official control application to your smartphone or tablet. The app offers advanced control modes:
- Bluetooth Connection: Connect your assembled model to the app via Bluetooth.
- Remote Control Mode: Use virtual joysticks and buttons on the app interface to control the model.
- Gravity Induction Mode: Control the model's movement by tilting your device.
- Path Mode: Draw a path on your device screen, and the model will follow it.
- Programming Mode: Utilize a visual block-based programming interface to create custom movement sequences and actions.
6.3 Model Specific Movements
Each model features unique movable parts and functions:
- Excavator: The joystick can swing, and the excavator arm and boom can move up and down.
- Robot: Features movable wings and hand joints.
- Mining Vehicle: The tipping bucket can be lifted and lowered.
- Lifting Platform: Can be elevated.

6.4 Scratch Programming Mode
The app's programming mode uses a visual "Scratch" like visual interface, allowing users to drag and drop command modules to create complex sequences. This mode is excellent for developing logical thinking and coding skills.
Key elements of the programming interface include:
- Return key: To go back to the previous screen.
- Connect Bluetooth: To establish a connection with the model.
- Command module combination: Area for arranging programming blocks.
- Run: Executes the programmed sequence.
- Save: Saves the current program.
- Command module: Individual blocks representing actions or commands.
