What was the name of the first robot that was used in the army?

The first robot used in the army is often considered to be "SRI International's Shakey," developed in the late 1960s. Although primarily a research project focused on Artificial Intelligence and robotics, Shakey's capabilities in navigation and task execution laid the groundwork for future military applications. Another notable early example is the "PackBot," which was deployed by the U.S. military in the early 2000s for bomb disposal and reconnaissance tasks.
