POWERplus Octopus Hydraulic Robot Arm Kit

Build Your Own Hydraulic Robot Arm

The POWERplus Junior Octopus is a DIY STEM construction kit that allows users to build a fully functional robotic arm. It provides a hands-on experience in assembling and controlling a multi-axis mechanical system.

Water Powered Hydraulic System

The arm operates using water hydraulics. After filling the system with clean water, pressure is applied through control levers to move different parts of the arm without the need for batteries or motors.

How the Model Works

The system uses interconnected cylinders and tubes filled with water. When a control lever is pressed, water pressure transfers force to another part of the system, enabling smooth and controlled movement.

6-Axis Movement Control

The robotic arm offers movement across six axes, including base rotation, arm lifting, wrist movement, and gripper control. This allows a wide range of motion similar to basic industrial robotic arms.

Functional Gripper and Suction Cup

The model includes two interchangeable end tools: a gripper for lifting small objects and a suction cup for handling flat surfaces. The arm can lift items up to approximately 50 grams.

STEM Learning Through Practice

This kit introduces core concepts such as hydraulics, pressure, force, and mechanical control systems. It supports hands-on learning through building and operation.

Skill Development

Assembly and use help develop fine motor skills, coordination, logical thinking, and problem-solving abilities. It also encourages interest in engineering and robotics.
