Hydraulic Arm Activity Pack
Build yourself a third arm! This is a pretty incredible hydraulic powered remote-controlled arm. Use it to pick up your room, eat snacks, stack blocks, play a game, or battle against other hydraulic arms -some of these tasks may be easier than others to complete!
The arm is built totally by you, from scratch! You construct it by measuring, cutting, reaming holes and tapping. This arm is "advanced," because it has 8 cylinders (4 cylinders move the arm, 4 cylinders form the control panel), and it has parts to make it into almost anything you can imagine. Build it using the instructions, then re-engineer it! Create your own unique design, incorporating recycled materials or anything else you can find. It comes with plenty of extra components included to help you change and create something completely new. Try re-engineering the arm so it can pivot at the base!
Hydraulic Arm Educational Goals

- Basic Build Guide: PDF or MS Word --Use this Guide if you’ve purchased the Basic Hydraulic Arm.
- Advanced Build Guide: PDF or MS Word
Engineering Challenge
- Design & Engineering Challenge: : PDF or MS Word -- Engineer your End Effector to dig, stack, and play games. Are you ready?.
Optional Resources
Available at two different learning levels, the TeacherGeek Engineering Notebook is designed to help students cycle thru the Design & Engineering Process and help them innovate and invent new designs. Use an Engineering Notebook page for each iteration of design. It is recommended that extra pages are printed and on-hand during activities.
Classroom Overview
- Classroom Overview: PDF or MS Word--A brief overview of TeacherGeek documents, activity procedures, educational alignment standards, concepts, vocabulary, background information, and supplementary resources.
STEAM Market-It Challenge
Add the STEAM Market-It Challenge to any completed TeacherGeek activity to teach students how to turn their TeacherGeek design into a retail product. Students will learn the 4 'Ps' of marketing - Product, Placement, Price and Promotion. Students have the option of completing a commercial, a billboard or retail packaging as a summative assessment.

If you are working with ages 12+, you can choose how to complete the Gears & Pulleys Activity.
- Choice #1 Without Labs: Go straight from the Build Guide to the Engineering Challenges. This option works well when you’re doing the activity outside of a classroom, in a Makerspace, as a self-directed activity, or just for fun.
- Choice #2 With Labs: Start with the Build Guide. Once your hydraulic arm is built, an Optional Lab is available to explore hydraulic and pneumatic power. You can apply this knowledge to the Engineering Challenge. This option works well when you want to teach this activity to a class or during a class visit to a Makerspace.
