This week was short. I spent most of the week refining the smaller details of the ROV
I started by figuring out what kind of cables we were using for the tether. I worked with Miles and determined that we needed two 18 gauge copper wires shielded to insulate 600 volts. We also need a two channel fiber optic cable to send and receive data.
I determined this so that I could design the strain relief. I needed to know the cable makeup to determine the minimum bend radius of the cable.
My estimations were pretty massive, so I had to redesign the strain relief to circle around the entire penetrator area. I realized that this was an opportunity to improve the ROV’s hydrodynamic efficiency. I added a non-sealed dome to organized the cables in the rear.
I digitally sketched the design but I ran out of time to model it.
I designed the split collars for the frame assembly. This component connects the bars and the panels in the frame.
I realized that most of the strain was on the hardware, so the strength of the connector wasn’t extremely important. So to cut down on manufacturing time, by resin printing them. This also cuts down on weight as well.
