Brainstorming

All three designs for the frame and propulsion of the ROV are similar in several ways. One way is that all of the frames are skeletal in nature. What the means is that there are no outer covering on any of the designs, only the frame itself. Also, all of the ROV designs are meant to be made of aluminum structure. Another way they are all similar is that for propulsion, a propeller is used rather than any other instruments of propulsion. In all designs, supports can be added for the cameras, lights, robotic arm, etc.

The first design is shaped like a rectangular prism. The propeller is located inside the structure of the ROV. It is also located in the rear of the ROV to push the ROV forward.

The second design is similar to the first. The structure is shaped like a rectangular prism. This design also has a tail, onto which the propeller is mounted. The propeller pushes the ROV like in the first design. However, in this design, the propeller is located on the outside of the structure rather than inside.

The third design is also rectangular in nature. Rather than having a tail, this design has an aluminum nose. The propeller is located inside the nose of the structure. From here, the propeller pulls the ROV rather than pushing. This will provide more control over the ROV, similar to how front wheel drive has more control than rear wheel drive in automobiles
