Unitree Z1 Pro: From Mobile Legs to Precision Arms

The Game-Changing Unitree Z1 Pro Arm

Unitree has been shaking things up in the world of quadruped robotics, offering more affordable robots to consumers and industries alike. But they didn’t just stop there—they’ve also jumped into the world of robotic arms and humanoid robots. One of their amazing creations is the Unitree Z1, a robotic arm designed to enhance the abilities of their quadrupeds. The goal is to see it utilized across various sectors, from retail to industry and beyond. Let's look closer at what makes this robot arm stand out.

From Opening Doors to Moving Objects

Attach the Z1 robot arm to the Unitree AlienGo or B1 quadrupeds; suddenly, these legged robots become even cooler and can do even more. With a maximum reach of 740mm and a payload of up to 5 kg, the arm extends the capabilities of the quadrupeds, with documented uses such as opening doors and moving small objects around the house.

The Z1 Pro can also function as a stand-alone product, capable of tasks ranging from working with a screwdriver on an assembly line to pouring a glass of wine at home.

Lightweight, Versatile, and Modular

Weighing just 4.5kg, the arm is lightweight and portable, making it easy to transport quickly and safely. With 6 degrees of freedom, it performs tasks with a high degree of flexibility and versatility. Plus, its modular design lets you swap out different attachments so that it can grip, weld, cut, assemble, and more.

This kind of versatility makes the Z1 Pro a top pick for situations where things are always changing. It can stick to a preset plan or adapt on the fly, thanks to its sensors that help it avoid obstacles and keep itself safe.

Precision and Control

With a tested repeatability of approximately 0.1mm, this arm is well-suited for tasks that require consistent accuracy across multiple runs, such as manufacturing, research, or delicate operations like pouring drinks into a glass. The arm's precision is supported by a range of sensors embedded in its motors. These sensors continuously monitor torque, angle, and velocity and have the ability to control the stiffness and damping of the motor. This means the arm can adjust not only the force but also the rate of application, allowing for precise control and movement across all joints of the robot.
