## Overview

The Hydraulic Arm Edge Kit is a DIY STEM/STEAM project that allows users to explore hydro-mechanical technology without the need for electricity or batteries. With 6 axes of movement and a versatile suction apparatus, this kit offers an engaging way to learn about robotics while developing engineering skills. Assembly is straightforward, thanks to detailed graphic instructions, making it an ideal choice for both beginners and seasoned builders.

## Description

Robotic arm technology just got a little more interesting with hydro-mechanically fun. With Hydraulic Arm Edge, you will command six axes of varied movements: the gripper to open and close up to 1.89 inches, wrist rotation of 180 degrees, wrist mobility of 98 degrees, elbow range of 44 degrees, base rotation of 270 degrees, and shoulder motion of 45 degrees. With a vertical reach of 16.35 inches, horizontal reach of 12.42 inches, and lifting capacity of 50g, your robotic friend is ready for your genius to erupt. With the removal of the gripper, you can activate the suction apparatus. This feature enables the user to elevate objects with a larger surface area (like a small mobile phone). Another prodigious attribution is a braking system that is integrated in the lever controllers to execute all commands accurately. WOW! How does this equate to fun? Your children will have total command and manipulation using the science principles of a Hydraulic system and its application. Easy to follow instructions with detailed graphic illustrations pave the way for successful and satisfying kit building. Compliment your engineering, math, science, and technology (STEM) learning strategy. No battery or motor required. It is powered by water; thus, the "Hydraulic" significance and how it manipulates axes movement via lever controllers. - For more than 3 decades, OWI continues its pursuit to satisfy educational instructors and the most discriminating parents. Hydraulic Arm Edge is recommended for ages 10 and up, but with its 229 assembly parts, it will challenge the beginner engineering enthusiasts.

## Questions & Answers

**Q: Is there any way to get  extra tubing? Mine was cut short**
A: Yes, but be willing to pay for it.  Unless you catch the error within 30 days of purchase (not receipt), they won't stand behind their product at all.

**Q: What kind of oil can be used as a replacement for the original?**
A: To be clear, by "oil" I assume you are referring to the lubricant that came in a small bag.  As Dohn Riley pointed out, some of the answers to this question are confusing the oil with the "hydraulic fluid" which is water in this case.  You can buy a replacement "oil bag" from the company for $1 plus shipping.  I suspect that the oil they use is a kind of mineral oil.  It has to be something that is safe for kids to get on their hands etc.  It looks and feels like drug store mineral oil but is more viscous.

**Q: Can you add the usb pack to this model**
A: This robot arm is the new model which is hydraulic and it does not require USB.  The hydraulic arm uses regular water to operate. The usb was used in earlier versions of the robot arm.Let me know if that helps.

**Q: Is this for left or right hand?**
A: Neither I use my feet 🤓
