Easy Hydraulic Machines





Introduction: Easy Hydraulic Machines

In this Instructable, I'll to show you how to build many projects that use a simple hydraulic system that kids in elementary school can build. Each step will show you one of four machines that use the same basic mechanism.

First thing's first: How to make a hydraulic system

Step 1: Simplest Machine

The video gives you an overview of the simplest hydraulic machine - the photos tell you how to build it! I've had kids as young as 1st grade build this project.

Step 2: Hydraulic Box

The hydraulic box is more challenging to build.

Step 3: Hydraulic Drawbridge

The hydraulic bridge project was originally conceived by a student named Daniel H.D. Thanks Daniel!

Step 4: Hydraulic Fortune Teller

The hydraulic fortune teller uses the same mechanics as the Judobot to achieve 3-dimensional movement, however this project is easier to build because it doesn't need to be thoroughly designed to battle. I like the idea of a fortune teller, but the face can be replaced with other things to create a variety of projects: a catapult arm, a serving basket, cannon.... be creative!

Thanks! This is gonna help me in my hydraulics proiect!

How many cc is that syringe? Please reply as soon as possible!!!

The syringes I use are 12ml, and filled to 10ml.

great for my hydraulic robotic arm project

I love to watching this video

we are doing this for a project too! long live projects!!!

#love of school

I made this for my Physics project relating to Pressure and it came in handy! It was simple to make and yet demonstrates the topic in the most easiest way to understand. I took a wooden stick from my attic and sawed it to wooden blocks. Also, the Vinyl tubing didn't fit to the tip of the syringe, so I made a small slit at the end of it and the tube fit in! Thanks a bunch WYE_Lance!
