5. Setup and Assembly
This robotic arm is provided as a DIY kit and requires self-assembly. Detailed installation instructions, videos, and schematic diagrams are included on the provided USB flash drive.
5.1 Pre-Assembly Checklist
- Ensure you have all components as per your selected kit configuration.
- Prepare a stable 12V 5A power supply (not included with all kits).
- Access the USB flash drive for comprehensive assembly guides.
5.2 Assembly Steps
- Refer to the "Installation instructions and video" folder on the USB flash drive for step-by-step visual and textual guides.
- Carefully assemble the metal frame components using the provided screws.
- Install the motors and bearings into their respective joints, ensuring smooth movement.
- Connect the wiring according to the schematic diagrams provided on the USB drive.
- Attach the chosen end effector (suction cup or gripper) if applicable.
- Connect the control board (if included) and power supply.
6. Operating Instructions
The robotic arm can be controlled via independent PC software or a mobile application using Bluetooth.
6.1 Software Installation
- Install the PC control software from the USB flash drive (look for "Software_english.zip").
- For mobile control, download the Android app.
6.2 Connecting to the Robotic Arm
- PC Connection: Connect the robotic arm to your PC via a compatible serial port or Bluetooth. The PC software supports simultaneous control via both methods.
- Bluetooth Connection: Enable Bluetooth on your mobile device or PC and pair with the robotic arm.
6.3 Basic Operation (PC Software Example)
The "Red Sun Global - Robot Arm four axis teaching controller" software allows for precise control and programming.
- Axis Control: Use the X, Y, Z controls to move the robotic arm along its axes. "Quick +" and "Quick -" provide rapid movement, while directional arrows offer fine adjustments.
- End Effector Control:
- "Gripper ON/OFF" to control the gripper.
- "Sucker ON/OFF" to control the suction cup.
- Calibration: Use the "Calibration" button to perform mechanical homing, which uses the XYZ switches to set the arm's reference position.
- Speed Settings: Adjust "Jog speed" and "Run speed" (5-100) to control the movement velocity.
- Coordinate Motion Recording: The software allows recording of coordinate motions and editing G-code. Each recorded move can have a separate delay and speed setting.
6.4 E-axis Slide Operation (Optional)
If an E-axis slide is installed, its movement can also be controlled via the software, extending the robotic arm's reach and workspace.
7. User Tips
- Android App Compatibility: Some Samsung phones may experience compatibility issues with the Android control app, specifically with WiFi connectivity. If your Samsung phone cannot find the robot's WiFi, try using a non-Samsung brand Android device.
- Software Updates: The developer (Red Sun Global) continuously updates the software with new features. Free upgrades for the computer software will be offered. Regularly check the provided USB drive or seller's resources for updates.
- Customization: The design allows for optional stepped fixtures or additional end effectors by adding an expansion kit. Explore these options for enhanced functionality.
8. Maintenance
- Keep Dry: As the robotic arm is not waterproof, ensure it is kept in a dry environment and protected from any liquids.
- Cleanliness: Periodically clean the metal components and joints to prevent dust and debris buildup, which can affect performance. Use a dry, soft cloth.
- Joint Inspection: Regularly inspect movable joints and bearings for any signs of wear or looseness. Tighten screws as necessary.
- Wiring Check: Ensure all wiring connections are secure and free from damage.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Robotic arm not powering on. | Incorrect power supply, loose connection, faulty power adapter. | Ensure a 12V 5A power supply is used. Check all power connections. Test with a different power adapter if available. |
| Robotic arm not responding to software commands. | Incorrect serial port selection, Bluetooth not paired, software not connected. | Verify the correct COM port is selected in the PC software. Ensure Bluetooth is enabled and paired. Click "Connect" in the software. |
| Android app cannot find robot's WiFi. | Samsung phone compatibility issue. | Try using a non-Samsung brand Android phone for control. |
| Inaccurate or erratic movement. | Loose mechanical connections, uncalibrated axes, motor issues. | Check all screws and mechanical joints for tightness. Perform a "Calibration" via the PC software. Inspect motor wiring. |
