Underwater Cave Exploration just got a whole lot easier thanks to NEMO

Published

NEMO

Cave diving is, per attempt, the single most dangerous sport on Earth. The men and women who take it on are regularly faced with cave-ins, blackouts, and panic-inducing conditions. On average, 20 cave divers a year don’t come back from a dive.

Corey Jaskolski has been working on a project which aims to give cave divers an additional tool they can use to keep safe while in pursuit of their passion.

Jaskolski is the President of Hydro Technologies and also serves as a National Geographic Innovation Fellow. Using 3D printing technology, he is currently working on the development of a remotely operated vehicle that can assist with the exploration of underwater caves.

Previous versions of UROVs needed to be powered from the surface and required 400-foot-long cables, each a half an inch in diameter and made of heavy, solid steel to reach down into the depths. The NEMO carries its power supply on board, and though still tethered, requires only a thin, fiber-optic cable of less than 4 lbs in total weight to connect to the surface.Working with engineering students from Colorado State University and additive manufacturing experts from Solid Concepts, Jaskolski’s team built an Underwater Remotely Operated Vehicle (UROV). The NEMO (Nautical Exploratory Modular Observer) was built using Fused Deposition Modeling and Selective Laser Sintering.

“There are great archeological teams unable to afford current UROVs,” said Jaskolski. “They can barely afford to travel out to these places for exploration. If we can make UROVs readily available, affordable, portable and easily replicable – and get them in the hands of the right people – then we will be able to make amazing discoveries in our lifetime.”

Jaskolski and his team knew they’d have to find a better way to build their dream UROV, so they turned to Solid Concepts.

“If everything had to be made by machining or molding without freedom to design one-off or two-offs, this would not have been possible,” he said. “It would have turned into months of machining and hundreds of thousands of dollars.”

Using 3D printing technology, the NEMO took just a few weeks to design, 3D print and ready for testing.

Michael Hake was the lead engineer on the NEMO team at CSU, and he says the process resulted in an easy-to-assemble package which allows all servos and thrusters to connect directly to the NEMO’s outer shell. That meant fewer total parts and manual assembly steps are involved.

“You can easily remove the shell without losing parts and reassemble when you reach your destination,” Hake says.

And the NEMO is more than a pretty face. It’s built to comfortably withstand depths of more than 60 meters.

Hake says that analytic testing has indicated that the NEMO might well function down to 190 meters. He adds that the team designed NEMO to be small enough that a pair of hikers can carry it to a given location, and that it could operate for more than 90 minutes without interruption.

World Rivers Day: Go with the flow during these river Drift Dives 

Published

on

Going with the flow is something we’ve all had to get better at doing this year. And becoming a PADI Drift Diver lets you take those skills to the next level, and just in time for World Rivers Day which is celebrated this Sunday 26 September. 

Drift diving can be both relaxing and exhilarating. The course teaches you how to enjoy going with the flow as you scuba dive down rivers or use ocean currents to glide along safely. It feels like flying – except that you’re underwater using scuba equipment. 

If you’re a PADI (Junior) Open Water Diver who is at least 12 years old, you can start your journey at home with the PADI Drift Diver eLearning course and then complete the specialty course with your local PADI Dive Centre or Resort.  

EXCLUSIVE: WIN a PADI Drift Diver eLearning course – click HERE to be in with a chance to win one of two eLearning courses from our friends at PADI to celebrate World Rivers Day!

Once you are certified as a PADI Drift Diver, you are ready to explore rivers, amongst other currents, all over the world. Here are some of the most remarkable river dive sites across the globe for you to seek adventure in. 

1. Valle Verzasca, Switzerland 

See a whole new side to Switzerland while doing a drift dive through the Valle Verzasca, which has some of the clearest diving in all of Europe. It is both an ideal place to learn to drift dive and still offers plenty of adventure for the more experienced divers. Exploring Valle Verde can be arranged through a range of PADI Dive Centres in the region and combined with mountain lake dives in the area as well. 

2. Rainbow River, Florida 

The clear, shallow and warm waters of Rainbow River in Dunnellon, Florida make it the perfect drift dive location for scuba divers, snorkelers and freedivers alike. PADI Dive Centres in the area can help organize pick up and drop offs so that you can drift down one of Florida’s most outstanding waterways. 

3. St Lawrence River, Canada

Drift diving in the St. Lawrence River can provide access to thousands of shipwrecks, including the RMS Empress of Ireland. Plus, the riverway is known to have surprisingly warm temperatures of up to 75 degrees Fahrenheit and have friendly visitors that include salmon, beluga whales, Greenland sharks and grey seals. If you plan it right, you can even dive between the two countries of Canada and the United States. 

4. Waikato River, New Zealand 

Zip by boulders and rainbow trout during a drift dive through the Waikato River on a guided dive with a PADI Dive Centre in the area. While the river water is likely to be a bit chilly, the drift dive ends at Hot Water Stream, where you can warm up and relax in a natural hot spring. 

5. Local Rivers Inspired by other PADI Drift Divers 

You don’t have to venture far to seek adventure with a drift dive. As Youtuber Scuba Jake explains on PADI’s recent Dive Stories Podcast, there is always something to discover beneath the surface—with rivers offering some of the most unique dive sites in the world. All you have to do is look below the surface and go with the flow. Your local PADI Dive Centre or Resort can give you additional insight on the best places near you.
