End-effector not included -- please select the desired manipulator or gripper from "D2 Accessories".
The Unitree D2 Dual-Arm Embodied Data Collection Kit is a complete bimanual robotic platform purpose-built for embodied AI research, imitation learning, and teleoperation data collection. The kit includes 2x D2 Basic robotic arms, each with 7 degrees of freedom and 44.3 lb·ft (60 N·m) maximum joint torque, delivering a total of 14 degrees of freedom for coordinated bimanual manipulation. Both arms are mounted on a dual-arm vertical stand configured for desktop mode, providing a compact, stable workstation for data collection tasks.
The integrated stereo depth camera delivers synchronized RGB-D perception of the workspace, enabling accurate 3D reconstruction, object pose estimation, and scene understanding -- critical inputs for training embodied AI models. Each arm is constructed with industrial-grade cross-roller bearings and internal-rotor permanent magnet synchronous motors, ensuring high precision and repeatability across thousands of data collection trajectories. Integrated with Cortex-M33 32-bit processors, each arm supports a 500 Hz control cycle and multiple control methods, including SDK, host computer, and drag-and-drop teaching.
2x robotic arms with 7 joints each deliver a fully integrated bimanual manipulation platform. Optimized for coordinated data collection and teleoperation tasks.
Integrated stereo depth camera provides synchronized RGB-D perception for 3D scene reconstruction, object detection, and pose estimation during data collection.
