This week, war robots came to Paris. On display at the Eurosatory 2016 Land and Airland Defence and Security tradeshow, RoBattle is a modular machine from defense firm Israel Aerospace Industries (IAI). Seven tons itself, it can carry three tons of sensors, weapons, and other tools it may need for fighting. And much like the first tanks that were built for the difficult war-scarred muddy ground of the Western Front, the RoBattle can climb over difficult terrain. Mostly.
