Hydraulics studies the flow and pressure of liquids. Since liquids are compressible only a small amount, they are much easier to use for transferring energy. Additionally, compared to pneumatic systems, hydraulics can achieve up to 100 times greater pressure in the same area.
Hydraulic devices and machines use special hydraulic oil. It’s easier to transfer force with oil than with water, and it also provides the necessary lubrication between parts. This works very similarly to the human circulatory system!
Now it’s time to test the principles of hydraulics in practice. Let’s build the robotic arm Lio!
