Man-a-trons were the 1980s version of humanoid robots deployed at trade shows and retail stores. These were early commercial androids designed for customer interaction and demonstration purposes. Think mechanical humanoids with limited articulation, pre-programmed speech patterns, and basic movement capabilities. They ran on pneumatic or early servo systems, nowhere near today's Boston Dynamics level but fascinating for their time. The tech was primitive by modern standards but represented early attempts at human-robot interaction in commercial spaces before digital screens dominated everything.
