Assembly Guidance and Classroom Use

Assembly takes approximately 40 to 60 minutes, making this kit suitable for a single class period or an after-school project. Recommended steps:

1. Sort and identify all components from the parts list.
2. Assemble the wooden frame and attach wheels or tracks following the provided instructions.
3. Install the mini DC motor, connect the gears or drive interface, and secure the motor in place.
4. Wire the battery holder and switch module, verifying connections before inserting batteries.
5. Test the crawler on different surfaces and adjust balance or gearing as needed to improve traction.

Safety and Tips

• Adult supervision is recommended for younger students when using tools or installing batteries.
• Use fresh AA batteries for consistent motor performance and remove batteries when storing the kit.
• Ensure all screws and nuts are secured to prevent loose parts during operation.
• Encourage students to record observations and iterate on design changes to learn engineering trade-offs.
