The Research and Self-Sufficiency Jihad Organization of the Iranian Army has demonstrated the capabilities of the new Heidair-1, which only has the processing power of a desktop computer from the early 1990s. Heidair-1 is a small, remote controlled ground vehicle designed to roll under tanks and other structures, all while being inexpensive an replaceable. The little robot has six wheels and antennas mounted on the back, with some models sporting mounted rifles. A video shows the robot rolling under a tank like shape and detonating, engulfing the ‘tank’ in flames and depicting a throwback to World War II when anti-tank mines were designed to crawl under the vehicle and detonate at the weaker spot in the armor.
