The Mayflower Autonomous Ship finally arrived on the coast of Nova Scotia last month, marking the end of its long trek across the Atlantic. While the modern Mayflower is far from the first vessel to make that voyage, this small robotic boat is the largest to ever do so navigated by artificial intelligence with no humans aboard. A few technical hiccups notwithstanding, its trip is the latest evidence that the future of the high seas could be autonomous. Slowly, self-steering ships are becoming a reality. In Norway, an autonomous battery-powered container vessel is shuttling fertilizer between a factory and a local port, and pending a successful trial, it could be fully certified within the next two years.

A robotic cargo vessel has passed through the Panama Canal for the first time. The uncrewed ship, an Overlord Unmanned Surface Vessel (USV) of the US Navy, made a 4700 nautical mile (8700 kilometre) journey including passage from the Atlantic to the Pacific almost entirely without human assistance. Pentagon spokesman Josh Frey says the vessel was in autonomous mode for over 97 per cent of the trip's length. A remote crew assisted when needed.

The first step in any machine learning project is typically to clean your data by removing unnecessary data points, inconsistencies and other issues that could prevent accurate analytics results. Data cleansing can comprise up to 80% of the effort in your project, which may seem intimidating (and it certainly is if you attempt to do it by hand), but it can be automated. In this post, we'll walk through how to clean a dataset using Pandas, a Python open source data analysis library included in ActiveState's Python. All the code in this post can be found in my Github repository. If you already have Python installed, you can skip this step.

Every day, more than 40 container ships pass through the Panama Canal. They chug over the narrow isthmus separating the Atlantic and Pacific oceans, navigating three sets of multi-chambered locks that carry them uphill to an enormous lake 90 feet above sea level. After crossing that, another network of locks lowers them to the opposite coast. The trip, which can take a full day depending on traffic, requires the careful choreography of skilled freighter pilots, tugboats, and the immense doors that separate each lock. As with most things these days, software keeps everything moving smoothly, but this most impressive feat of civil engineering relies upon a hodgepodge of systems added piecemeal over the decades.
