Building Progress 3: controller and complete assembly

   This week we concentrated on the assembly of controller and the main body. Also, a simple test was made after the complete assembly.

figure 1: the assembled controller

      Figure 1 shows the shape of the controller. There are totally 4 swithes attached to the control box. Two toggle swithes that located on the main plane control the action of left and right propellers separately. Two push-button switches are located on the top of the control box which correspond to the rise and sink of seaperch.


Figure 2: the arrangement of wires

     Figure 2 shows the inner arrangement of wires. Red/black cables are linked to the anode/cathode of the battery and the power cards in the control box. The thiner green wires are linked to the right starboard corresponding to the motor on right side. Similarly, the thiner blue wires are linked to the left starboard corresponding to the motore on left side, and the orange wires are linked to the up/down motor.
   Finally, a simple test had run to test the underwater performance of the seaperch. A short video will be uploaded in a few minutes.
