Highlights

XTac UMI G1 is a multimodal UMI data-collection gripper whose fingertips carry Xense's own visuotactile sensors, seeing exactly where, how hard and how stably every contact happens. A handheld demonstration records touch, vision and pose in sync, turning out high-quality robot manipulation data for imitation learning, VLA model training and tactile research.

Core value

  • Lower cost, shorter data path

    Capture, synchronization and tooling live in one system, turning human demonstrations straight into trainable data.

  • Natural handling, efficient collection

    The wearable form follows the hand's own motion, is quick to learn, and suits long, multi-task sessions.

  • From "watchable" to "understandable" data

    Beyond recording that "the hand moved", it tells whether, where and how stably contact happened.

  • Traceable data at scale

    Standardized output and fleet deployment; data is easy to review, compare and reuse.

Six highlights

  • Close-up of the fingertip visuotactile sensor

    Visuotactile fusion, real interaction

    High-frame-rate tri-color visuotactile sensors record contact location, grasp stability and slip trends in sync.

  • Holding a leader gripper

    Close to the human hand, faster collection

    The wearable leader gripper is light and easy to pick up, covering grasping, carrying, insertion, thin-part picking and more.

  • Two leader grippers with live pose axes overlaid

    High-precision pose, high-quality data

    Multi-device time sync of 5ms and positioning accuracy of < 3mm; every stream is aligned to the same instant.

  • Data path from gripper and backpack through the toolchain to the cloud

    Mainstream ecosystem, data ready to use

    Native support for LeRobot, MCAP and other mainstream formats and tools, so data is ready for training as soon as it is collected.

  • A wearable collection unit

    Light deployment, built for scale

    A light leader gripper and a wearable collection unit, ready for the lab, home or field.

  • Fingertip picking up a fine chain

    Compliant fingertips for fine grasping

    Slim, compliant fingertips make small parts, thin sheets and edge-lying objects easier to pick up.

Applications

Office desk Tools and workbench Picking from a shelf

  • Embodied-AI data factories: large-scale manipulation data collection across many stations, operators and tasks.
  • Robot algorithm R&D: a source of real interaction data for robotics companies, university labs and embodied-AI teams.
  • Home and service robots: tidying desks, picking and placing items, opening containers, using tools.
  • Flexible industrial manipulation: 3C assembly, small-part sorting, cable insertion, part picking.
  • Tactile and real-interaction research: contact-state understanding, tactile representation and tactile foundation models.
