Kragerø, NorwayFebruary 25 2010
Every since I was a child my family has spent summers at our cabin in Kragerø. I've always been fascinated by the ocean life, and as I began experimenting with electronics I realized I could combine my two interests. Early 2010 I started working on my first ROV, and since then I've had a few successful voyages. My goal is to create a robust ROV system, so I can explore the kelp forests and ship wrecks around Jomfruland. Currently my expeditions have all been close to shore, but there is plenty to see none the less.Read background

This time I didn't design everything from scratch, but used the OpenROV design for the mechanics (Electronics and software I did myself however). And for a change the ROV is still in good shape after it's maiden voyage! I plan to perform some upgrades in time for this summer vacation, and hopefully be able to do some proper exploring.
During the testing of this ROV I saw cod, cuckoo wrasse, star fish, and sea urchins.
My second expedition, this time with my second ROV design. Saw starfish, spiny starfish, whiting, ballan wrasse, cuckoo wrasse, sea urchins, sea anemones, and a lion's mane jellyfish. Deepest dive was around 19 meters. This ROV has since died, as after the deepest dive salt water had penetrated the connectors, and corroded the internal electronics. Since the entire unit is cast in epoxy, no repair is possible.
My first ROV expedition, just around the dock and rocks where we usually swim. Saw a lion's mane jellyfish, plenty of sea weed, and some small fish. This ROV was later dismantled and used to construct a second version, which was cast in wax. It died shortly after testing.
I have made three successful expeditions so far, all close to shore. The first two ROVs were designed from the ground-up by me, whereas the last ROV was based on the OpenROV design. My goal is to explore the coast-line around Jomfruland, where there are kelp forests, ship wrecks, and much to see.
