WESTBOROUGH, Mass. -- Amazon says it plans to open a $40 million robotics innovation hub west of Boston.
Amazon says it has created more than 4,000 full-time jobs in Massachusetts and has invested over $3 billion in the state since 2011.
Amazon's robotics division has been focused on making warehouse robots that stack and move goods at its distribution centers.
Massachusetts has been the center for Amazon's robotics research since the company acquired North Reading-based Kiva Systems for $775 million in 2012.
