5. Configuració i programació
5.1. Instal·lació de la bateria
Insert two (2) 3.7V 18650 lithium batteries into the battery case, ensuring correct polarity. Connect the battery case to the designated power input on the main board.
5.2. Software and App Installation
The kit supports graphical programming and Mixly. Detailed tutorials and programming code are provided to guide you through the process. For mobile control, download the dedicated '4WD Robot Arm Smart Car' application (Android only) from the provided resources or app store.
5.3. Connexió Bluetooth
To connect via Bluetooth, ensure the robot car is powered on and Bluetooth is enabled on your Android device. Open the '4WD Robot Arm Smart Car' app. The app will automatically detect and connect to the robot when it is in close proximity.
6. Instruccions de funcionament
The LAFVIN Robot Arm Car offers various modes of operation and control. Familiarize yourself with each function to maximize your learning and play experience.
6.1. Robotic Arm Control
Control the robotic arm's movements (open, close, lift, lower) using either the mobile app or the IR remote. The app provides a visual interface for precise control.
6.2. Save and Execute Arm Actions
The mobile app allows you to record a sequence of robotic arm movements and save them as an 'Action'. You can then execute these saved actions with a single command, enabling complex tasks like 'Auto-Carry'.
6.3. Anti-Drop Function
The robot is equipped with sensors that detect edges, preventing it from falling off elevated surfaces like tables. This function can be activated via the mobile app.
6.4. Gravity Sensor Control
Utilize your smartphone's gravity sensor to control the robot's movements. Tilt your phone to steer the robot, providing an intuitive control experience.
6.5. Line Tracking
The robot can follow a black line on a light surface using its line tracking modules. This feature is ideal for creating mazes and programmed paths.
6.6. Ultrasonic Obstacle Avoidance
The ultrasonic module allows the robot to detect obstacles in its path and autonomously navigate around them, preventing collisions.
6.7. Following Obstacles
In this mode, the robot will follow an object or person at a set distance, using its ultrasonic sensor to maintain proximity.
7. Manteniment
- Keep the robot clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Regularly check all screw connections to ensure they are tight.
- Inspect wires for any signs of wear or damage. Replace damaged wires immediately.
- Store the robot in a dry, cool place away from direct sunlight and extreme temperatures.
- Remove batteries if the robot will not be used for an extended period to prevent leakage.
