The New York Police Department has deployed a K5 security robot in the Times Square-42nd St. subway station to aid in surveillance during nighttime hours. The K5 robot is equipped with HD cameras, microphones, and AI capabilities to detect unusual activity. It’s part of a trend where police departments and businesses across the country are using robots for security purposes. Knightscope, the company behind the K5, uses AI to power its robots, helping them navigate and detect potential threats.
