Extra Digital Wooden Assembly Kit Excavator STEM Educational Toy

The Extra Digital wooden assembly kit excavator is a STEM educational toy designed to develop engineering skills and logical thinking. This hands-on construction set allows users to build a functional model, providing an engaging way to learn about mechanical principles. The assembled model is operated manually using a water-pressure-powered hydraulic system, helping children understand the basic principles of hydraulics, engineering mechanics, and robotics.

Advantages

This construction kit serves as a toy and an educational tool, transforming complex physics theories into a hands-on learning experience. The model operates entirely without electricity or batteries, as all movement is generated by water pressure. During assembly, children develop fine motor skills and precision, while testing the model reinforces scientific concepts. The structure is made from high-quality, non-toxic, laser-cut wood, ensuring durability and safety. The kit is designed for easy assembly, allowing for independent work or collaborative activities with parents.

Suitable for

• Home learning and educational projects
• Classroom demonstrations in schools
• Developing fine motor skills and logical thinking
• STEM-focused hobbyist activities

This kit may not be suitable for children under the age of 3 due to the presence of small parts that pose a choking hazard. It is also not intended for heavy-duty construction tasks, as it is a delicate educational model designed for demonstration and play.

Key specifications

• Material: Laser-cut wood, metal, and plastic
• Dimensions: 300 x 220 x 185 mm
• Weight: 190 g
• Control system: 8-syringe hydraulic mechanism
• Power source: Manual water pressure

To assemble the excavator, follow the provided manual to connect the wooden parts using the included screws and glue. Once the structure is built, fill the syringe system with water according to the instructions. The four control syringes are connected by flexible tubes to the working syringes on the excavator arm. By pressing or pulling the pistons on the control base, you transfer pressure through the tubes, which causes the working syringes to extend or retract, enabling the arm to lift, lower, bend, or rotate.

What to consider before purchase

• Ensure the child is within the recommended age range of 6-8 years and above
• Verify that the workspace is suitable for handling water during the filling process
• Check that all components are present before beginning assembly

For the best experience, consider using different colored water in the syringes to easily identify which control corresponds to each specific movement of the excavator arm.
