This package pairs the Unitree Z1 Pro, the higher-payload model of Unitree's 6-axis Z1 arm, with the Z1 Gripper as its end effector, so the arm and the gripper arrive as one order rather than two. Unitree designs the Z1 as an onboard manipulator for mobile robots, for work from e-commerce logistics to everyday handling, and it can also be used as a compact bench-top arm.
The Z1 Pro weighs 4.5 kg, reaches 740 mm and carries at least 3 kg, against the Z1 Air's 2 kg at 4.3 kg. Repeatability is about 0.1 mm. Every joint moves at up to 180°/s: J1 ±150°, J2 0–180°, J3 −165° to 0°, J4 ±80°, J5 ±85° and J6 ±160°. It runs from 24 V at more than 20 A with a 500 W maximum, connects over Ethernet and is programmed from Ubuntu, with position-plus-force control, force feedback and collision detection.
Unitree is open about the trade-off in that design. The joints use relatively low reduction ratios, so position-control stiffness is low, and without an optimised control mode the arm shows position error and shake in motion; repeatability also depends on the test conditions. For force-sensitive work and controlled contact that is the right compromise, and for rigid, high-precision positioning it is a point to plan the control software around.
The Z1 Gripper's stroke, grip force and weight, and the usable payload with the gripper fitted, are confirmed in writing with your quotation. If you already own a Z1 Pro, the gripper is also sold on its own, and for depth sensing at the jaws the Z1 grippers with Intel RealSense cameras are the alternatives.
Key Capabilities
-
Arm and Gripper in One Order: The Z1 Pro arrives with the Z1 Gripper as its end effector, rather than as two separate purchases.
-
At Least 3 kg Payload: The Pro carries at least 3 kg at a 4.5 kg arm weight, more than the 2 kg of the Z1 Air.
-
740 mm Reach, ~0.1 mm Repeatability: Six axes reach 740 mm with repeatability of about 0.1 mm, depending on test conditions.
-
Position Plus Force Control: Force feedback and collision detection support controlled contact with objects and surroundings.
-
Built for Mobile Robots: Running from 24 V with a 500 W maximum, the Z1 is designed to mount on mobile platforms as an onboard manipulator.
-
Ethernet and Ubuntu: The arm connects over Ethernet and is programmed from Ubuntu through Unitree's open programming interface.
