## Overview

The Hydraulic Robotic Arm Model Kit is a 203-piece STEM experiment set that lets you build a 16-inch wearable robotic hand powered by water-driven hydraulic pistons. Adjustable for left, right, or claw-like configurations, it offers precise finger articulation and gripping strength to lift objects up to 6kg. Designed for ages 14+, this hands-on kit teaches pneumatic and hydraulic principles without motors or batteries, making it a perfect blend of education and interactive engineering fun.

## Description

♥ Features:- Challenge yourself to pick up and hold items of different shapes and sizes!- Build your own wearable mechanical hand that you operate with your own fingers.- No motors, no batteries — just the power of air pressure, water, and your own hands!- Three configurations: right hand, left hand, and claw-like; adjustable to fit virtually any human hand.- Hydraulic pistons enable the mechanical fingers to open and close and grip objects with enough force to lift them. - Every finger joint can be adjusted to different angles for precision movement.- Water-powered pistons control each of the fingers, which are articulated in three different points.- Adjustable joints allow for precise control and amazing gripping capabilities.- Learn how pneumatic and hydraulic systems are used in industrial robots such as automobile components. - children will have total command and visual manipulation using the science principles of a hydraulic system and its application. - The hydraulic robot arm is recommended for ages 14 and up, but with its 203 assembly parts, it will challenge the beginner engineering enthusiast .♥ Specification:Material: ABS plasticSize: 36.7*28.8*7.5 cmWeight: 1.5 kgBearing weight: 6kg♥ Package Includes:1 * Hydraulic Robotic Arm Kit1 * User Manual

## Features

- ★ Use the 203 pieces to assemble a 16-inch robotic hand that slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers. During assembly, you'll conduct experiments with different parts of the mechanical hand to learn more about air and water power and hydraulic transmissions.
- ★ Explore hydraulics, pneumatics, and robotics with your very own hydraulic hand! Using over 203 plastic pieces and piston tubes that you fill with water, build an awesome mechanical hand that uses hydraulic power to simulate the movements of the human hand no motors or electricity required!
- ★ Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items anything with reach!
- ★ The hand can be configured in three ways left hand, right hand, and claw-like, with the thumb in the center and can be adjusted to fit virtually all hand sizes. Water-powered pistons control each of the fingers, which are articulated in three different points. Adjustable joints allow for precise control and amazing gripping capabilities.
- ★ A user manual guides model building and experimentation and provides engaging scientific information about how pneumatic and hydraulic systems are used in industrial robots to assist with a variety of tasks in our modern world.
