Manual Homemade Hydraulic Arm

A manually controlled Hydraulic arm, made out of simple materials like wood, hot glue and syringes (for the hydraulic pistons). Its total length (when fully deployed) is 40+cm and can lift weights up to 300g. Its disadvantages: its slow and impressice.
The compression unit is made out of ordinary 6V motors which operate under the signals of electronic pulses, generated by the controll unit. In order to compress the liquid inside the hydraulics (water), the motors twist a screw that transforms the circular motion to linear. Therefore the stationary syringes which have smaller volume (2.5ml) than the ones on the arm(5.0ml) compress the water which, since not compressible, causes the large syringes on the arm to expand. Notice that the volume difference of 2.5 - 5.0 ml doubles the pressure of the 5.0 ml syringes.
The controll unit is a Basic Stamp 2 microcontroller which, under the instructions of the buttons on the controller, sends pulses or activates the relays that operate each motor.

What if you had some stepper motors?

Excelent point!

Indeed that would make things a lot better. However, back then i didn't so I had to work with whatever was around.

Actually, this was one of my bad projects, too slow and too inacurate. You can check out the rest of my videos for more "interesting" stuff.

Thanks for commenting!

Very interesting, Pascal's Law is clearly in effect here, as well as some simple kinematics.
