The move will leave 91 people without jobs, although they may find positions quickly given the thriving robotics industry.

While Eckert didn't go into detail as to why sales were low, the Boston Globe attributes it to one main rival: Universal Robots. While many credit Rethink with breakthroughs in accessibility for collaborative robotics, Universal had a slight head start (it was founded three years earlier than Rethink, in 2005) and has had success creating a deep platform that translated to healthy sales. It just sold its 25,000th bot in September. As sad as it may be to see Rethink go, it's leaving precisely because the market for worker robots is very healthy.
