National Geography Hydraulic Robot Arm

The National Geographic Hydraulic Robot Arm is an engaging DIY science kit that introduces children to the fundamentals of hydraulics and mechanical engineering. Designed for hands-on learning, this kit allows users to build a fully functional robotic arm powered entirely by water, eliminating the need for batteries or motors.

Key Features

• Hydraulic Control System: Utilizes four pairs of syringes to manage various movements:

  • Syringes 1 & 4: Lift and lower the arm

  • Syringe 2: Open and close the gripper

  • Syringe 3: Rotate the arm up to 120 degrees

  • Multi-Axis Movement: The arm offers a range of motions, including:

  • Gripper opening up to 47 mm (1.89 inches)

  • Wrist rotation of 180 degrees

  • Wrist mobility of 98 degrees

  • Elbow movement range of 44 degrees

  • Base rotation of 270 degrees

  • Shoulder motion of 45 degrees 

• Reach and Capacity: Features a vertical reach of 16.35 inches, a horizontal reach of 12.42 inches, and can lift objects weighing up to 50 grams (1.75 ounces).

• Suction Mechanism: The gripper can be replaced with a suction component, enabling the arm to pick up objects with smooth surfaces.

• Educational Value: Ideal for children aged 8 and above, this kit fosters an understanding of STEM concepts through interactive play.

• No Batteries Required: Operates solely on hydraulic power, making it an eco-friendly and safe option for young learners.
