Advanced Snap-Fit System: The innovative snap-fit system allows for quick and easy assembly and disassembly of parts. Use the provided extraction tool for detaching locked components.
Video: Mechanics Cams & Cranks Overview. This video demonstrates the assembly process and the functionality of the Engino Mechanics Cams & Cranks kit, showcasing how various components connect and operate.
Understanding Cams & Cranks
This kit is designed to teach the principles of motion and power transmission through cams and cranks. You will learn how these mechanisms convert rotational motion into linear or oscillating motion.

Theory & Quiz Book: The included book provides fascinating facts, theories, and a quiz section to deepen your understanding of mechanical principles.

Experiments Section: Engage in step-by-step scientific activities to learn by doing, applying the theoretical knowledge to practical models.
Building Models & Experiments
The kit allows you to build 8 different working models, each demonstrating unique applications of cams and cranks. These models include:

8 Models to Build: Explore various mechanical concepts by constructing models such as a Fishing Crane, Flying Eagle, Moving Bridge, Moving Figurine, Oil Drill, Sewing Machine, Stationary Bike, and Wind Mill.

Featured Experiments:
- Build an Oil Pump: Construct a working model of an oil pump to understand how different simple machines work together and how cams convert motion.
- Build an Eagle with Flapping Wings: Assemble a flying eagle model to observe how rotational motion becomes linear through linkages, creating flapping wing movement.
- Build a Fishing Crane: Construct a fishing crane to learn how a crank helps to set the device into motion and lift heavy loads.
Maintenance
This Engino kit requires minimal maintenance. Keep all parts clean and stored in their original packaging or a suitable container to prevent loss. Avoid exposing parts to extreme temperatures or direct sunlight for prolonged periods.
Troubleshooting
If you encounter difficulties during assembly, please refer to the following:
- Double-check the step-by-step instructions in the manual or the 3D app.
- Ensure all parts are correctly oriented and securely snapped into place.
- If a part is difficult to remove, use the provided extraction tool as shown in the Advanced Snap-Fit System diagram.
