Photos: Robots at Work and Play

Advancements in robotics are continually taking place in the fields of space exploration, health care, public safety, entertainment, defense, and more. These machines--some fully autonomous, some requiring human input--extend our grasp, enhance our capabilities, and travel as our surrogates to places too dangerous or difficult for us to go. Gathered here are recent images of robotic technology, including a machine built to draw portraits, battle robots, a dance performance, an autonomous mobile vending machine, an art installation, an agri-bot, a robotic priest, a Mars rover, a grocery-store bot, and much more.
