Product Introduction

Introduction

The Exoskeleton Teleoperation Device is an exoskeleton‑based system for AlphaBot, developed independently by AI² Robotics. It is primarily designed for data collection, teleoperation, and human-robot interaction research.

With this exoskeleton teleoperation device, the operator can control the humanoid robot in an intuitive and natural manner, meeting application requirements in multiple scenarios including human-robot collaboration, operation data collection, remote control, and AI training.

Product Name	ZM Exoskeleton Teleoperation Device
Product Model	DC-EX2
Core Features	1:1 Isomorphic Design: The teleoperation kinematics fully match the degrees of freedom, length, and end gripper control characteristics of AlphaBot robot arms. High-Precision Motion Capture: Equipped with single-turn absolute encoders to record joint angle data, ensuring high precision and stability for scientific research and industrial-grade applications. Comfortable Operation Experience: Built-in dampers in each joint provide moderate friction resistance, simulating the feel of dragging a real manipulator for natural motion. Adjustable Ergonomic Design: The left and right teleoperation arms can be spaced apart using aluminum profile rails to accommodate different shoulder widths. The mobile stand supports height adjustment and can be lowered for seated operation. Casters on the stand allow flexible positioning of the device. Gravity Compensation: The gravity compensation system effectively reduces operating fatigue and improves comfort during long-duration operation.
Application Scenarios	Fixed-site data acquisition High-precision operation tasks Complex operations requiring force feedback Fixed operations such as PCB loading/unloading, retail, and assembly line tasks

Components

The exoskeleton teleoperation device consists of three main components:

• Teleoperation Arms: Includes left and right teleoperation arms, corresponding to the left and right robotic arms of the humanoid robot.

  Feature	Description
  Degrees of Freedom	Each teleoperation arm has 7 degrees of freedom.
  End-Effector Grip	Each teleoperation arm is equipped with a control device at its end-effector, capable of simulating the opening and closing actions of a humanoid robot’s end-effector gripper and dexterous hand.
  Operation Feel	Built-in dampers provide moderate frictional resistance, simulating the feel of dragging a real robotic arm for enhanced naturalness.
  Data Acquisition	Single-turn absolute encoder per joint for high-precision angle data.

  

• Mobile Stand: Supports height adjustment for standing or seated operation; equipped with casters for mobility and positioning.

  

• Gravity Compensation: Uses telescopic hook balancers to reduce operating load and enhance long-duration comfort.
