Syringe attachment โ The piston in the syringes are transfer work done by me to work done by the hydraulic arm by hydraulic force. A total of 4 pairs of syringes are used in the control of the arm.
Fig. 9
1. Use an electric drill to create a hole at the end of the piston of the syringe large enough so that it could rotate while a toothpick is in the hole, as shown in figure 9.
Fig. 10
2. Wrap the syringe with two cable zip ties, one around the circumference of the syringe and one for a small opening for another toothpick to go into, as shown in figure 10.

3. Attach the two syringes to the arm. One syringe is attached so that it controls the motion of the primary arm relative to the base, and another is attached so that it controls the motion of the secondary arm relative to the primary arm. Figure 11 shows the side view of how it should look like.

4. Figure 12 shows how the syringe-attached model looks like from the top.
Fig. 13
5. Figure 13 shows the movement of the arms due to the extension and compression of the syringes.
