Imagine a world where intelligent machines move around busy cities in the morning, alongside human activity. Autonomous delivery drones or robots navigate urban mazes to deliver fresh groceries, essential medicines, and lunch orders directly to doorsteps. Intelligent robots and drones inspect cities, assist traffic management, take charge of urban maintenance, hospitals have AI-powered robots efficiently deliver medications to patients, and warehouses have robots sort, pack, and ship orders. This is the emerging reality of Physical AI, not science fiction. By 2035, there could be as many as 1.3 billion AI-powered robots operating globally, unlocking a multi trillion-dollar market in manufacturing, healthcare, and transportation. Physical AI combines AI algorithms with robotics, sensors, and actuators to create systems that perceive, reason, and act in physical environments. It enables machines to interact directly with their surroundings, making decisions based on sensor data and executing actions through actuators. This technology has the potential to revolutionize industries by automating complex tasks, improving safety and efficiency, and creating robots and machines that are not just tools but partners in solving humanity's greatest challenges.
