The robotic machines can detect explosives and drugs within the range of 3km. The value of each machine is Rs. 85.5 million. Those detectors have been designed to sense explosives and weapons hidden in the human body automatically.
The government of the People's Republic of China donated these robots in September. Chinese Ambassador in Sri Lanka Cheng Xueyuan officially handed them to President Maithripala Sirisena at President’s Office.
