Setup: Assembly Instructions
Follow the detailed steps in the included educational instruction book to assemble your Rexbot. The assembly process involves connecting the 106 building pieces to form the robot's structure and integrating the motor unit.
- Unpack Components: Carefully remove all 106 pieces from the packaging and lay them out on a clean, flat surface. Verify all pieces are present against the list in the instruction book.
- Review Instruction Book: Before starting, thoroughly read through the entire instruction book to understand the assembly sequence and identify key components.
- Step-by-Step Assembly: Follow the diagrams and written instructions in the book precisely. Each step will guide you on how to connect the various building bricks and rods.
- Motor Integration: The motor unit is a crucial part of the robot's movement. Ensure it is installed correctly according to the instructions. Pay close attention to the orientation of the motor and its connection points.
- Battery Installation: Once the motor unit is securely in place, open the battery compartment (usually located on the motor unit itself). Insert 2x AA batteries, ensuring the correct polarity. Close the compartment securely.
- Wheel Attachment: Attach the wheels as directed. Ensure they are firmly in place but can rotate freely.
- Final Checks: After completing all steps, double-check all connections to ensure they are secure and that no pieces are loose. Confirm that the wheels and any moving parts can articulate without obstruction.
