The article discusses how Ukrainian startups are developing low-cost robots to aid in the war effort against Russia. These robots, built from commercial components, are being used for reconnaissance, demining, and even combat roles. One startup, Defensor, has created a small tracked robot that can be equipped with a grenade launcher or machine gun. Another, Adron, produces aerial drones for reconnaissance and targeting. The robots are relatively inexpensive, costing a few thousand dollars each, compared to millions for military-grade systems. While lacking advanced features, their low cost allows Ukraine to deploy them in large numbers. The startups are working around the clock to meet demand, with Defensor producing up to 10 robots per day. The article highlights the ingenuity and resourcefulness of these companies in supporting Ukraine’s defense against the Russian invasion.
