An arm, in place of a head
The front-mounted articulated arm defines D.O.G.Y. 2. Its forward-reaching configuration replaces the companion-style head, giving the robot a distinct manipulation-focused identity.
THE MOBILE MANIPULATOR
D.O.G.Y. 2
Digital Omni-gait Gyro-stabilized Yaw-bot
Four legs.
A new reach.
Quadruped mobility meets purposeful manipulation. D.O.G.Y. 2 pairs a sculpted four-legged body with a front-mounted robotic arm and a two-finger gripper, opening a new direction for supervised, hands-on robotics.

Unitree As2 + R1-7a arm concept
This is an arm-integration concept. As2 measurements refer to the unmodified quadruped; the R1-7a is the seven-axis arm reference. Neither component specification establishes the complete robot’s reach, lifting capacity, stability or runtime. The selected As2 edition, mounting structure, gripper and controls require engineering validation.

ABOUT D.O.G.Y. 2
Let’s get
specific.
How does D.O.G.Y. 2 differ from D.O.G.Y.?
D.O.G.Y. focuses on a dog-inspired face and companion interaction. D.O.G.Y. 2 replaces that head with a front-mounted arm and two-finger gripper, making mobile manipulation its defining development direction.
How much can the arm lift?
The finished system’s lifting capacity has not been confirmed. It depends on the arm, gripper, mounting, reach and quadruped stance. The As2’s carrying-load figures must not be interpreted as arm lifting capacity.
Can it walk while carrying an object?
Coordinated movement and manipulation are intended development goals. Supported objects, grasp positions and motion limits will be published after complete-system testing.
