Introduction
This manual provides comprehensive instructions for the assembly, operation, and maintenance of your HEXBUG VEX Robotics Robotic Arm. This construction kit is designed to introduce principles of science, technology, engineering, and mathematics (STEM) through hands-on building, allowing users to explore the mechanics of industrial robots.
Safety Information
This product contains small parts. Adult supervision is recommended during assembly and operation, especially for younger users. Keep all components away from small children to prevent choking hazards. Always handle tools and components with care to avoid injury.
What's Included
Your HEXBUG VEX Robotics Robotic Arm kit includes over 350 VEX Robotics pieces, along with the necessary components to build the robotic arm and two alternate models. Please verify all components are present before beginning assembly.
- Various structural and mechanical parts for construction
- Gears, connectors, and fasteners
- Instruction manual with detailed diagrams

Assembly and Setup
The VEX Robotics Robotic Arm is a construction kit requiring careful assembly. Follow the detailed, step-by-step instructions provided in the included manual. Ensure all pieces are correctly identified and connected as shown in the diagrams. Take your time to ensure each connection is secure for optimal functionality.
Alternate Builds
In addition to the primary robotic arm, this kit allows for the construction of two alternate models: a chopper and a scorpion. Instructions for these alternate builds are available through the manufacturer's website or may be included in the manual. These alternative designs offer additional building challenges and extend the play value of the kit.


Operating Instructions
The VEX Robotics Robotic Arm features multiple points of motion for precise control. Each function is typically controlled by a dedicated knob or lever, allowing for independent manipulation of the arm's movements.
Movement Controls:
- Move Up/Down: Use the designated control to lift and lower the robotic arm, adjusting its vertical position.
- Move In/Out: Operate the control for extending and retracting the arm, allowing it to reach objects at varying distances.
- Rotate 360°: Turn the base control to rotate the entire robotic arm a full 360 degrees, providing access to objects from all directions.
- Claw Open/Close: Manipulate the claw control to open and close the gripper, enabling the arm to pick up and release objects. The claw has a maximum grip of 5.5 inches.


Maintenance
To ensure the longevity and optimal performance of your VEX Robotics kit, follow these maintenance guidelines:
- Cleaning: Wipe down components with a dry or slightly damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the plastic.
- Storage: Store the assembled model or disassembled parts in a cool, dry place away from direct sunlight and extreme temperatures. Keep small parts in their designated bags or containers to prevent loss.
- Inspection: Periodically check for any loose or damaged parts. Ensure all connections are secure and gears mesh smoothly. Replace any broken components promptly to maintain functionality and prevent further damage.
Troubleshooting
If you encounter issues with your VEX Robotics Robotic Arm, consider the following steps:
- Movement Issues: If the arm's movement is stiff or unresponsive, ensure all gears and linkages are correctly aligned and free from obstruction. Re-check the relevant assembly steps in the manual for any missed or incorrect connections.
- Claw Malfunction: If the claw does not open or close properly, verify that the claw mechanism's dial or lever is securely connected and that the claw pieces move freely without binding. Check for any small debris obstructing the mechanism.
- Missing Parts: Refer to the detailed parts list in the instruction manual to confirm all components are present. If parts are missing from a new kit, contact HEXBUG customer support immediately for assistance.
- General Instability: Ensure the base is assembled correctly and placed on a flat, stable surface. Loose connections can lead to instability.
