I had finished to remove the supports of all the parts so I started to construct the arm. The first step was to fix a servo to the basis. I used Parallax servos that Nicolas gave me while waiting to receive the MG995 servos. They have the same technical specification but the length between the screw holes of the Parallax is a bit larger than the MG995's so I struggled a little. I then fixed the second servo that is the shoulder of the arm.

To power the arm, I received a 5V 3A power supply and a DC jack connector to which I connected the 5V and GND cables. But before that, I needed to connect together both of the servos 5V and GND wires so Vladimir told me to solder them. I started by twisting together two cables to connect both servos, then I twisted a third wire that will be plugged in the DC jack connector. To make sure the connections will resist I solder the cables. This was for the GND connection but I don't think I had the correct technic to do it because for the 5V wires I struggled so I asked Vladimir and did it differently.

I wanted to test the rotation of the two servos before the end of the class but didn't have enough time for it so I finished it at home and tested it. A few days later I received the MG995 servos and I replaced the Parallax before the next session.
