Building Progress 2: Motors

     This week, we made three motors for our seaperch.
     Because the seaperch is used in the water, the most important thing is to keep the motors dry, or they won't anymore if they have contact with water. We used electrical tape to wrap the motors. Then, we connected each motor to a wire by soldering. After that, we put the motors into three film cans and used wax to fix and warp up the whole motors. And the propellers were connected to the motors at the outside of the film cans, because the propellers are the power of movement. Figure 1 below shows one of the motors is fixed on the seaperch.

Figure 1: One of the motors fixed on the seaperch.

     Two motors are fixed on the back of the seaperch. One is on the left and another one is on the right. If both motors are running, the seaperch can go forward or backward. And the seaperch can also turn around by running only one motor. Figure 2 and Figure 3 below show the front side and the left side of the seaperch.

Figure 2: Front side of the seaperch with three motors.

Figure 3: Left side of the seaperch with three motors.

      From Figure 2, we can see the third motor is vertically fixed in the middle of  the seaperch. Apparently, this motor controls the seaperch to go up or down. Besides, the two wires, which are connected to the left and right motors in the back is green and blue. And the wire connected to the middle motor is orange. These are important to be used in the next step: remote controller. Since the controller we received is the old version, which is different from others, we need put more work on the remote controller in this week's lab.
