Dex5-S Dexterous Hand

22 DoF per hand. Effortless dexterity, at your command

Price from $6,350
Compact & Precise1:1 Human Hand Scale

Coming closer than ever to true human hand size, the Dex5-S takes on far more complex, intricate tasks than the bulky dexterous hands of the past.

  • 22DOF

    Greater dexterity and more degrees of freedom deliver more comfortable, more stable grip angles.

  • Actuation

    All 22 motors are direct-drive and backdrivable with dual encoders, plus a new roll axis on the pinky. These features dramatically elevate whole-hand grip dexterity.

  • Bending Endurance Test

    Ultra-long bending life. Stable and reliable.

Ultimate Impact Protection

When a joint motor of the dexterous hand takes an extreme external impact, the impact protection structure shields the gears from damage. All 22 DoF are protected.

Power

The best training is training uninterrupted by overtemperature alarms. The Dex5-S handles up to 2 kg payload per hand, and 1 kg continuous working payload.

Three Interface Options

Supports a wide 15–65 V input range.

Pick your connection: Gigabit Ethernet, USB, or high-speed RS-485. With the Gigabit Ethernet configuration, the palm camera plugs straight into the hand, no more external cabling.

Precision

Built on precision micro gearboxes.
