Hydraulic Excavator Model is a hands-on STEM project that allows students to build and control a realistic excavator using hydraulic power.

Using syringes and fluid-filled tubes, students can operate the excavator’s arm, bucket, and rotation — just like real construction machines.

This kit introduces learners to fluid mechanics, engineering design, and machine control systems in a fun and highly interactive way.

Key Features

✔ Real hydraulic control system (4-channel control)

✔ Fully functional excavator arm movement

✔ 360° base rotation

✔ DIY assembly (step-by-step learning)

✔ Safe wooden + plastic build

✔ No electricity required (pure hydraulic system)

✔ Real-world engineering simulation

How It Works (Scientific Principle)

• Pressing a syringe pushes liquid through tubing

• Pressure is transmitted to another syringe

• Movement occurs in the excavator joints

👉 Based on Pascal’s Principle (Hydraulics)
