"Hydroelectric" robotic arm

This is a Grade 12 pre-engineering project. As the name states, it has both hydraulic (syringes) and electric component (the motor that does the rotation). It combines a variety of materials, including 3d printed, laser cut (they were designed so, but cut by hand), and sheet metal parts. The base it rotates around contains a bearing made up of 15 mm marbles.

Stl files for 3d printed parts, svg for lase cut parts and plans for sheet metal parts are provided. Follow the photographs and screenshots. Ask any questions you have.
