Hydraulic Arm - "6. Linking control syringes to actuating syringes"

*** The procedure and figures are not representative of the entire methodology, since I was not able to capture every step while making. ***

Linking control syringes to actuating syringes: Each actuating syringe on the hydraulic arm has to be attached to a control syringe. The water inside the syringes that make movement possible is dyed with a unique colour to avoid confusion.

1. Fill 4 water cups with water and prepare a watercolor paints, as shown in figure 16.

2. Dye the water in the 4 water cups with a unique color. Figure 17 shows the dyeing of one of the water cup with red. Figure 18 shows the water cups after all of them are dyed with a unique color.

3. Link the control syringes filled with dyed water to the actuating syringes with a rubber tube, as shown in figure 19. Make sure that the actuating syringes are completely pressed to minimize the amount of air bubbles in the syringes and the rubber tube. Repeat this process for all 4 actuating syringes in the hydraulic arm.

5. Place a 100g mass to the rotating base of the hydraulic arm to prevent the arm from losing balance. Stick the mass with an instant adhesive as shown in figure 21.
