Scientific assembly experiment・Three-in-one hydraulic manipulator without motor・No battery required・Safe and reliable Three-in-one free replacement, lots of fun

Three-in-one hydraulic mechanical arm, this is a mechanical arm that can be driven by water without batteries or motors. The pressure of water is converted into power so that the joystick can easily control the joint activities of the mechanical arm, exercise children's logical ability, explore scientific principles, use imagination, and feel the fun brought by the hydraulic mechanical arm.

Just add water, pressurize the five joysticks at the rear end of the arm, and transmit hydraulic power to drive the robotic arm to perform various actions such as turning, rising, gripping, stretching, and suction.

Move your hands and discover science
Hands-on assembly is both a toy and a science education.

Integrate into the international STEAM education concept
Cultivate children's solving ability, logical thinking, and creative inspiration.

science class
Understand the power principle of the hydraulic arm. The three-in-one hydraulic mechanical arm is a mechanical arm that can be driven by water without batteries or motors. The pressure of water is converted into power so that the joystick can easily control the joint activities of the mechanical arm, exercise children's logical ability, explore scientific principles, use imagination, and feel the fun brought by the hydraulic mechanical arm.

Exploring hydraulic power, magic and fun
Convert water pressure into power

Hydraulic principle analysis:
The liquid is closed and cannot flow, and the container cannot be transferred. The liquid is in the container, and one end of the force will transmit the pressure to the other end to realize the transmission of force.
