Where it performs

  • Dual-arm configuration allows for complex, cooperative manipulation tasks.
  • Integrated edge computing, 3D vision, and HMI for advanced applications.
  • Supports voice interaction and VR teleoperation for flexible control.

What to check before buying

  • Limited payload of 1 kg per arm restricts lifting of heavier objects.
  • Fixed base design means no inherent mobility; requires external transport.
  • Total 17 degrees of freedom, but distributed across two arms, not single effector.
