Is Russia developing a drone army?

Emerging from a lake, a giant amphibious drone gingerly picks its way over Russia's Rzhevka military training ground. This huge drone is the latest in a menagerie of automated robots to be developed worldwide, adding to what some have described as the creation of ground-based robotic armies. Its appearance comes as large organisations, such as Google and Amazon, invest in drone technology, with some experts claiming the it could lead to a full on robotics war by 2020. Air-based drones have been under development in Russia for some time, with reports last year that the country had been developing a new 20-tonne attack unmanned aerial vehicle (UAV). These latest images, however, provide a glimpse into Russia's future capabilities in ground-based drones.
