Invented in 2001 by iROBOT, PackBots were specifically designed to perform military operation by the US Army in Afghanistan in detection of minefields, clearing bunkers and caves and searching building and hideouts of terrorists in 2002. US military personnel launched around 800 PackBots around Iraq and Afghanistan to carry out several operations in gathering information details regarding war. These PackBots are small running robots which could be deployed very easily and even carried in a backpack. Because of its GPS system and advance sensors it helped in explosive detection and bomb disposal campaigns. It could also analyze the war situation by reading and monitoring the environmental conditions.

Stanley is a car robot invented at the Stanford University by Stanford Racing team together with Volkswagen Electronic Research Laboratory (ERL). It is also an award winning robot of cash prize $2 million at the 2005 DARPA robot challenge where it covered 132 miles in just 6 hours and 54 minutes in the course of California’s Mohave Desert. It ran with the average speed of 19 miles per hour in such terrain by analyzing with inbuilt GPS and LIDAR system that helped in position maintenance.
