Design your own “robotic”, remotely-controlled hydraulic arm with TeacherGeek. Use it to pick up your room, eat dinner, stack blocks or compete against other fluid-powered arms – it’s totally up to you! Tap, ream, screw and cut real components, outfitting three cylinders to move the arm and three cylinders to form the control panel.

Incorporate recycling bin and found materials to re-engineer a truly innovative design. Learn about hydraulic and pneumatic power, Pascal’s Law and introductory robotics in this true STEM project.

If you are working with ages 6-11, 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.
