When Google (GOOGL -1.97%) acquired rugged robot maker Boston Dynamics last month -- its 8th robotics acquisition over the last year – iRobot (IRBT 0.58%) CEO Colin Angle speculated Google may have been targeting commercial applications related to its self-driving cars.
 
The most likely end game for Google, he stated, was "low-hanging fruit" in package delivery. After all, Google would need robots to carry packages from the car to consumers' doors, and who better than Boston Dynamics and its incredible bevy of dynamically lifting, balancing robots to do so?
 
Meanwhile, iRobot has made no mystery of its intentions of ultimately bringing bots based on its AVA telepresence platform into our homes to serve as antonymous butlers.
 
But according to the Fool's Steve Symington in the following video, Google threw a wrench in Angle's speculation when it acquired smart-thermostat maker Nest this week for $3.2 billion. Specifically noting Nest is, at its core, yet another robotics company, Steve thinks this signals an unmistakable -- and, if you're iRobot, worrisome -- push by Google toward automating our homes.
