Boston Dynamicsthe Massachusetts robotics company known for its four-legged robots and humanoids, is undergoing a leadership change.

Robert Playter announced in an internal memo Tuesday that he is stepping down as the company’s chief executive, as previously reported by A3. Amanda McMaster, the company’s chief financial officer, will stand down for the top job while the company searches for a replacement.

TechCrunch has reached out to Boston Dynamics for more information.

Playter took the helm of Boston Dynamics in 2020, taking over from founder Marc Raibert. Playter worked at Boston Dynamics for 30 years, where he held other roles, including vice president of engineering and chief operating officer.

Boston Dynamics was founded in 1992 by Raibert as a spinoff from the Massachusetts Institute of Technology, where he was a professor. Google’s parent company Alphabet bought Boston Dynamics in 2013, before selling the company to Japanese investing conglomerate SoftBank in 2017.

Hyundai, its owner, acquired the company in 2021.

The robotics producer is best known for its quadruped robot, Spot, which the company commercialized in 2020 shortly after Playter took the helm. The company most recently announced Atlas, a humanoid robot.
