As the human population continues to rise and the amount of industry increases, almost no part of the globe feels the burdens of this activity more than the oceans. Whether it’s temperature change, oxygen or carbon dioxide content, or other characteristics, the study of the oceans will continue to be an ongoing scientific endeavor. The one main issue, though, is just how big the oceans really are. To study them in-depth will require robots, and for that reason [Mike] has created an autonomous boat.
This boat is designed to be 3D printed in sections, making it easily achievable for anyone with access to a normal-sized printer. The boat uses the uses the APM autopilot system and Rover firmware making it completely autonomous. Waypoints can be programmed in, and the boat will putter along to its next destination and perform whatever tasks it has been instructed. The computer is based on an ESP module, and the vessel has a generously sized payload bay.
While the size of the boat probably limits its ability to cross the Pacific anytime soon, it’s a good platform for other bodies of water and potentially a building block for larger ocean-worthy ships that might have an amateur community behind them in the future. In fact, non-powered vessels that sail the high seas are already a reality.

Everyone knows plastic trash is a problem with junk filling up landfills and scattering beaches. It’s worse because rather than dissolving completely, plastic breaks down into smaller chunks of plastic, small enough to be ingested by birds and fish, loading them up with indigestible gutfill. Natural disasters compound the trash problem; debris from Japan’s 2011 tsunami washed ashore on Vancouver Island in the months that followed.
Erin Kennedy was walking along Toronto Island beach and noticed the line of plastic trash that extended as far as the eye could see. As an open source robot builder, her first inclination was to use robots to clean up the mess. A large number of small robots following automated routines might be able to clear a beach faster and more efficiently than a person walking around with a stick and a trash bag.
Erin founded Robot Missions to explore this possibility, with the goal of uniting open-source “makers” — along with their knowledge of technology — with environmentalists who have a clearer understanding of what needs to be done to protect the Earth. It was a finalist in the Citizen Science category for the 2016 Hackaday Prize, and would fit very nicely in this year’s Wheels, Wings, and Walkers challenge which closes entries in a week.
Join me after the break for a look at where Robot Missions came from, and what Erin has in store for the future of the program.

When I started the Automate the Freight series, my argument was that long before the vaunted day when we’ll be able to kick back and read the news or play a video game while our fully autonomous car whisks us to work, economic forces will dictate that automation will have already penetrated the supply chain. There’s much more money to be saved by carriers like FedEx and UPS cutting humans out of the loop while delivering parcels to homes and businesses than there is for car companies to make by peddling the comfort and convenience of driverless commuting.
But the other end of the supply chain is ripe for automation, too. For every smile-adorned Amazon package delivered, a whole bunch of waste needs to be toted away. Bag after bag of garbage needs to go somewhere else, and at least in the USA, municipalities are usually on the hook for the often nasty job, sometimes maintaining fleets of purpose-built trucks and employing squads of workers to make weekly pickups, or perhaps farming the work out to local contractors.
Either way you slice it, the costs for trash removal fall on the taxpayers, and as cities and towns look for ways to stretch those levies even further, there’s little doubt that automation of the waste stream will start to become more and more attractive. But what will it take to fully automate the waste removal process? And how long before the “garbage man” becomes the “garbage ‘bot”?

Feel like taking a long walk, but can’t be bothered with carrying your drinks? Have no fear, this “Follow Me” Cooler Bot is here!
Really just a mobile platform with a cooler on top, the robot connects to smartphone via Bluetooth, following it using GPS. Making the platform involves a little woodworking skill, and an aluminium hub with a 3D-printed hub adapter connects the motors to a pair 6″ rubber wheels with a swivel caster mounted at the rear. A pocket in the platform’s base houses the electronics.
The Arduino Uno — via an L298n motor driver — controls two 12V DC, brushed and geared motors mounted with 3D printed brackets, while a Parallax PAM-7Q GPS Module in conjunction with an HMC 5883L compass help the robot keep its bearing. A duo of batteries power the motors and the electronics separately to prevent any malfunctions.

Last year we wrote about Hackerbot Labs’ autonomous boat, which project members hope to someday circumnavigate the globe. Now called Project Ladon, progress continues apace with a recent ocean test of their modified 18’ kayak, the TSV Disputed Right of Way. The kayak’s internal spaces contain a pair of lead-acid truck batteries controlled by a home-brewed control system that uses relays to control the craft’s trolling motor, with a Beaglebone and Arduino Mega under the hood.
The test was not exactly a success, with the boat actually avoiding the waypoints rather than sticking to them. Fortunately the team was aboard a chase boat so they were able to keep tabs on the craft. Unlike a quadcopter, which just falls down, a watercraft that borks may never be seen again.
Entered into the 2016 Hackaday Prize, the project has continued to gather steam, with presentations at both Toorcamp and Maker Faire Bay Area. In addition, they’re maintaining their Hackaday.io project site as well as a Patreon page.
Check out a couple of videos after the break! The test video is 360-degrees so you can drag around the POV.

De-lousing is a trying agricultural process. It becomes a major problem in pens which contain the hundreds of thousands of salmon farmed by Norwegians — the world’s largest salmon exporter — an environment which allows the parasite to flourish. To tackle the problem, the Stingray, developed by [Stingray Marine Solutions], is an autonomous drone capable of destroying the lice with a laser in the order of tens of thousands per day.
Introduced in Norway back in 2014 — and some areas in Scotland in 2016 — the Stingray floats in the salmon pen, alert and waiting. If the lice-recognition software (never thought you’d hear that term, huh?) detects a parasite for more than two frames in the video feed, it immediately annihilates it with a 530 nanometre-wide, 100 millisecond laser pulse from up to two metres away. Don’t worry — the salmon’s scales are reflective enough to leave it unharmed, while the pest is fried to a crisp. In action, it’s reminiscent of a point-defense laser on a spaceship.

It may look more like a Companion Cube than R2-D2, but the ISS is getting an astromech droid of sorts.
According to [Trey Smith] of the NASA Ames Research Center, Astrobee is an autonomous robot that will be able to maneuver inside the ISS in three dimensions using vectored thrust from a pair of turbines. The floating droid will navigate visually, using a camera to pick out landmarks aboard the station, including docking ports that let it interface with power and data. A simple arm allows Astrobee to grab onto any of the hand rails inside the ISS to provide a stable point for viewing astronaut activities or helping out with the science.
As cool as Astrobee is, we’re intrigued by how the team at Ames is testing it. The droid is mounted on a stand that floats over an enormous and perfectly flat granite slab using low-friction CO₂ gas bearings, giving it freedom to move in two dimensions. We can’t help but wonder why they didn’t suspend the Astrobee from a gantry using a counterweight to add that third dimension in. Maybe that’s next.
From the sound of it, Astrobee is slated to be flight ready by the end of 2017, so we’ll be watching to see how it does. But if they find themselves with a little free time in the schedule, perhaps adding a few 3D-printed cosmetics would allow them to enter the Hackaday Sci-Fi Contest.
