Three Models, One Stack: The Architecture Behind Whole-Body Control
Unlike the previous generation of Gemini Robotics, which primarily controlled a robot's upper body, the new VLA model can direct an entire humanoid from top to bottom [3]. Gemini Robotics ER 2 sits above it as the high-level agent: it streams video, audio, and text to plan multi-step tasks that can run for several minutes, then hands off the actual motor execution to lower-level VLA models [2].
The efficiency play is Gemini Robotics On-Device 2, which runs locally on the robot itself and can adapt to a completely new robot body using just a few hours of data, fewer than 200 demonstrations [1]. That flexibility shows up in the demos: the same stack drives Apptronik's Apollo through its five-fingered, 22-joint hand well enough to tie knots and seal a ziplock bag, then runs a simpler two-fingered gripper on a different platform without a rebuild [3]. DeepMind lists Boston Dynamics and Agile Robots among the hardware partners already plugged into the stack [4], with Franka also named as a partner platform [2], positioning Gemini Robotics as a single model stack designed to span humanoids, industrial arms, and mobile robots rather than being tied to one proprietary robot.
