OVERVIEW
The AgileX Universal Master Arm is a lightweight 6-DoF teleoperation leader arm (also called a master arm) built for real-time robot following through 6D pose mapping and IK-based motion control. At just 0.6 kg, it gives researchers, educators, and developers an affordable way to teleoperate compatible AgileX robotic arms and collect high-quality manipulation data for imitation learning and embodied AI.
The Universal Master Arm is available as a left arm for left-hand users, a right arm for right-hand users, or a right and left arm bundle for dual-arm setups. It supports Python, C++, and ROS2, making it a practical teleoperation leader arm for labs building data pipelines around the AgileX PiPER and NERO robotic arms. Third-party robot arms can also be integrated by adapting the robot model, IK solver, and control interface.
Key facts:
- Type: 6-DoF teleoperation leader arm
- Weight: 0.6 kg
- Latency: 0.1 ms
- Position accuracy: ±5 mm
- Compatible follower arms: AgileX PiPER and AgileX NERO (third-party arms with integration work)
- Software: Python, C++, ROS2
- Warranty: 1-year InDro warranty and support
WHAT APPLICATIONS IS THE UNIVERSAL MASTER ARM BUILT FOR?
- Leader-Follower Teleoperation: Drive a compatible AgileX follower arm in real time using intuitive handle-based control.
- Robot Learning & Data Collection: Capture high-quality demonstration data for imitation learning, ACT, and diffusion-policy pipelines.
- Education: An accessible, low-cost entry point for teaching robot kinematics, teleoperation, manipulation, and human-robot interaction.
- Research: A flexible platform for secondary development in manipulation, control, and embodied AI research.
- Validation: Bench-test motion strategies and control algorithms before deploying to a full robotic arm.
HOW DOES THE AGILEX UNIVERSAL MASTER ARM WORK?
A leader arm is the input device in a leader-follower teleoperation setup. The operator moves the leader arm by hand, and a follower arm reproduces that motion. The AgileX Universal Master Arm uses a 6-DoF mechanical linkage with a handle that rotates through ±180°, so the operator can move it like a natural extension of their hand.
Onboard 16-bit encoders track joint motion with ±1° angular accuracy and stream 6D pose data over a USB Type-C interface with 0.1 ms latency. That pose data drives an inverse-kinematics (IK) motion-mapping pipeline, which translates the operator's hand movements into joint or Cartesian commands for a follower robot. The result is ±5 mm position accuracy across a 505 mm hemispherical workspace.

FREQUENTLY ASKED QUESTIONS
What is the AgileX Universal Master Arm?
The AgileX Universal Master Arm is a 6-DoF teleoperation leader arm used for data collection, robot learning research, and controlling compatible follower robots in real time.
What is a teleoperation leader arm?
A teleoperation leader arm (also called a master arm) is a hand-operated arm that sends the operator's motion to a follower robot arm, which reproduces it in real time. It is also a practical tool for recording demonstration data for imitation learning.
How much does the AgileX Universal Master Arm cost?
A single left or right Universal Master Arm costs $700 USD. The right and left arm bundle costs $1,300 USD.
Which follower arms work with the Universal Master Arm?
It works with robotic arms from AgileX Robotics, including the 7-DoF AgileX NERO and the 6-DoF AgileX PiPER. Third-party arms can be integrated by adapting the robot model, IK solver, and control interface.
Do I need both a left and right Universal Master Arm for bimanual teleoperation?
Yes, for two-handed setups. The left and right arms are side-specific and cannot be cross-controlled, so each hand needs its matching arm. The right and left arm bundle covers both.
Is the Universal Master Arm suitable for education and research labs?
Yes. At 0.6 kg and with a low-cost, rapid-deployment design, it suits university labs, secondary development, and teaching robot teleoperation and kinematics without the cost of a full robotic arm setup.
