Familiarize yourself with scientific concepts 

Hydraulics do not create any new energy (no combustion) instead it transforms existing energy into a new, usable system that operates without fuel or electricity. Hydraulics operate on a push system where the fluid is pushed through the system to transform the energy.

Entire arm needs to be built, Once the arm is built just add water and use as a robotic arm.
