The security robots are made by a company called Knightscope, located in Mountain View. The K5 version uses lasers, thermal imaging sensors, 360 video, air quality sensors, a microphone and various other technologies to deter and detect criminal activities. In the event of suspicious activity, the robot alerts local human authorities. Stacy Dean Stephens, Knightscope vice president of marketing and sales, told NBC Bay Area that the company does not think the robots are dangerous. "This is a horrific accident, but we believe the technology and the machines are incredibly safe and we will continue to do our best to make sure that they are," Stephens said.
