Assembly Instructions
The K96164 kit allows for the construction of five distinct robot models. Refer to the included printed instruction manual for detailed, step-by-step assembly guides for each model. The blocks are small, self-locking, and compatible with Lego-style systems.
General Assembly Tips:
- Organize your blocks by color and type before starting to simplify the building process.
- Follow the diagrams in the instruction manual carefully.
- Ensure all connections are secure for structural integrity and proper electronic function.
- Pay close attention to the placement of electronic components like the LED display and light tubes during assembly.

This image showcases the five unique robot configurations that can be assembled using the building blocks provided in the kit.
Charging the Robot
The robot is powered by a rechargeable battery. Before first use, ensure the robot is fully charged.
- Locate the charging port on your assembled robot.
- Connect the provided USB charging cable to the robot's charging port.
- Connect the other end of the USB cable to a standard USB power source (e.g., computer USB port, USB wall adapter).
- The LED indicator on the robot (if present) will show the charging status. Refer to the specific model's manual for indicator behavior.
- Once fully charged, disconnect the USB cable.
Operating the Robot
Your robot can be controlled using the included 2.4GHz remote control or a dedicated mobile application.
1. Remote Control Operation (2.4GHz)
- Ensure the robot is powered on.
- Turn on the 2.4GHz remote control.
- The remote and robot should automatically pair. If not, refer to the printed manual for pairing instructions.
- Use the joysticks and buttons on the remote to control the robot's movement (forward, backward, turn) and activate features like bullet launching or LED expression changes.
2. Mobile Application Control
Download the official control application from your device's app store. The app offers multiple control modes:
- Standard Remote Control Mode: Mimics the physical remote control interface.
- Gyroscope Mode: Utilizes your mobile phone's gravity sensor to control the robot's movement by tilting your phone.
- Path Mode: Allows you to draw a path on your phone screen, and the robot will follow the drawn trajectory.
- Programming Mode: Offers a graphical drag-and-drop interface for creating custom movement sequences and actions.

This image illustrates how the mobile phone's gravity sensor is used to control the robot's movement trajectory in gyroscope mode.

This image demonstrates the path mode, where users can draw a trajectory on the mobile app for the robot to follow.
3. Programming Mode
The programming mode uses a visual, drag-and-drop block-based interface. This allows users to create custom sequences of commands for the robot.
- Open the programming interface in the mobile app.
- Drag and drop command blocks (e.g., Start, Infinite Loop, Loop Count, Terminate/Pause, Forward, Left Turn, Backward) onto the workspace.
- Arrange the blocks to create your desired program.
- Execute the program to see your robot perform the programmed actions.

This image displays the programming interface, featuring graphical drag-and-drop instruction blocks for creating custom robot behaviors.
4. Robot Features
- Movable Joints: Many robot models feature movable hand joints and rotatable heads for dynamic posing and interaction.
- LED Display: The LED display module can switch between various expressions, adding personality to your robot.
- Dazzling Lights: Integrated light tubes provide multiple colored light effects that can switch between each other.
- Functional Accessories: Some models include features like openable front covers, tracks for forward movement, and rotary switches for launching small projectiles.

This image highlights key features of the 'Super Warrior' robot model, such as movable hand joints, an openable front cover, a rotary switch for bullet launching, tracks for movement, an LED display, and dazzling light components.

Maintenance
Cleaning:
- Use a soft, dry cloth to wipe down the robot and remote control.
- Avoid using water or cleaning solutions, as these can damage electronic components.
- For hard-to-reach areas, use a soft brush or compressed air.
Storage:
- Store the robot and its components in a cool, dry place away from direct sunlight and extreme temperatures.
- Keep away from dust and moisture.
- If storing for an extended period, ensure the rechargeable battery is partially charged (around 50%) to prolong its lifespan. Avoid storing with a completely empty or full battery.
Battery Care:
- Only use the provided USB charging cable.
- Do not overcharge or deep discharge the battery.
- If the robot will not be used for a long time, charge it every 3 months to maintain battery health.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot does not turn on. | Battery is depleted. | Charge the robot using the USB cable. |
| Remote control does not connect. | Remote control batteries are low or not paired. | Replace remote control batteries. Refer to manual for pairing instructions. Ensure robot is on. |
| Robot moves erratically or not at all. | Loose block connections or interference. | Check all block connections. Move away from other 2.4GHz devices. Recalibrate if using app control. |
| LED display or lights not working. | Loose connection or component damage. | Check the connections of the LED display and light tubes. Ensure they are correctly installed as per the assembly manual. |
| App control issues. | Bluetooth not enabled, app not updated, or pairing issue. | Ensure Bluetooth is enabled on your device. Update the app to the latest version. Re-pair the robot with the app. |
