The Land Transport Authority deployed a robot at the Hougang MRT station yesterday to test its navigational and surveillance capabilities. Developed by ST Engineering, the 1.6m-tall robot was equipped with seven cameras to allow it a 360-degree view of its surroundings. Dr Rohan Gunaratna, who heads the International Centre for Political Violence and Terrorism Research at RSIS, said that transport nodes remain “attractive” targets to terrorists. He said, “What is essential is not only to train security personnel but non-security staff serving MRT stations to detect suspicious activity. Working with commuters to raise public awareness is paramount.”
