“Do-It-Yourself Engineering” S:1 E:19 Design a Hydraulic Arm

S:1 E:19 Design a Hydraulic Arm Plunge into hydraulics, learning how force is transmitted from actuators to hydraulic cylinders through fluid-filled lines. Then use this knowledge to design and build a hydraulically powered mechanical arm that can grasp and manipulate a concrete block – controlled by four hand-operated syringes. Along the way, use 3D printing to fabricate several crucial parts.
