Since 1984 there have been 38 robot-related accidents, according to a Zdnet review of OSHA statistics.
"Of the 38 incidents, 27 resulted in a worker's death. For comparison, in 2013, when the last US worker was killed in a robot-involved accident, there were 4,585 workplace fatalities in the US overall, according to the Bureau of Labor," according to Zdnet.
Recent robot-involved worker deaths in India and Germany have renewed the conversation about robot safety in the workforce.
