    Don’t Make Your Battlebot Out Of A Pumpkin

    It’s that time of year again. The nights are getting longer and the leaves are turning. The crisp fall air makes one’s thoughts turn to BattleBots: pumpkin-skinned BattleBots.

    If you’re asking yourself, “could a laser-cut plywood bot, sheathed in a pumpkin, stand up against an all-metal monster”, you haven’t seen BattleBots before.

    Halloween Robots: Trick or Treat?

    It’s Halloween and as you are working in your office or lab, you hear behind you the soft whir of a motor and then are startled by a voice that says “Happy Halloween! Please take some candy, then press the done button.”

    In research supported by the National Science Foundation, three members of the Robotics Institute at Carnegie Mellon University sent their CoBots on an experimental Trick-or-Treat romp through each floor of an office building. This experiment with a pair of costumed, autonomous robots was designed to observe human behavior in the presence of robots.

    The CoBots carry Sharp IR distance sensors with a range of 10 to 80 cm.

    This experiment showed some interesting results of human behavior in the presence of robots. Robots do not have to act like a human if they are operating in an activity that humans are, by nature, motivated to complete.
