SoftBank Group is taking over Google parent Alphabet's robot dreams, buying Boston Dynamics to pursue a future when more machines intermingle with humans.

As part of the transaction with Alphabet, SoftBank also agreed to buy Japanese bipedal robotics company Schaft. Terms of the deal weren't disclosed.

Boston Dynamics, bought by Google in 2013 as part of a robotics acquisitions spree, made its name with a series of two- and four-legged machines that are able to stay upright even when pushed or traversing rocky terrain. Videos of the robots, known for their animal-like movements, are popular on YouTube. While SoftBank has already made investments in robotics, those efforts have yet to deliver hit products or pay off. That may change with this new deal.
