Xynova Flex 2 Dexterous Robot Hand
The Xynova Flex 2 is a 23 degree of freedom bionic robot hand that combines tendon and direct drive actuation in a package of about 400 g. Micro linear actuators provide a 12 kg single hand grasp load, while back drivable joints, slip detection and a replaceable soft skin support durable, compliant manipulation in factories, service robots and humanoid platforms.

Xynova Flex 2 Dexterous Robot Hand
Robot hands usually force a trade. Tendon driven designs are light and nimble but can feel vague under load. Direct drive designs are precise but heavy and bulky. The Xynova Flex 2 refuses to choose. By combining tendons with direct drive motors in one hybrid system, it packs 23 degrees of freedom and a 12 kg grasp into a hand that weighs about the same as a human one. The result is a dexterous hand built to leave the lab: strong enough for real handling work, compliant enough to work near people, and engineered to keep running through millions of open and close cycles.
Key Features
23 Degree of Freedom Bionic Design
The Flex 2 mirrors a human hand in size, joint layout and kinematic structure. Xynova reports a perfect score in the Kapandji thumb opposition test, a clinical measure of how fully a thumb can reach across the palm, which supports free extension and strong shape adaptation when grasping irregular objects.
Light and Fast
At about 400 g, the hand is close to the weight of a human hand, which reduces the load on the wrist and arm it is mounted to. It can complete two full fist extensions per second for agile, responsive motion.
Strong Grip From Micro Linear Actuators
Compact micro linear actuators power the fingers, giving a single hand grasp load of 12 kg and a rated continuous operating load of 4 kg. The palm surface is wear and puncture resistant for repeated handling.
Precise, Back Drivable Control
Repeatability of ±0.1 mm keeps motions consistent from cycle to cycle. Because the joints are back drivable under load, the hand supports hybrid force and position control, with force control accuracy down to 0.05 N.
Perception and Reflexes
Multimodal perception fusion and what Xynova describes as a human like "cerebellum" enable adaptive grasping, slip detection and compliant reflexes. According to published reports, the sensing system combines force, vision, tactile and proximity inputs. An open development ecosystem supports customization and integration.
Built for Daily Duty
Xynova rates the Flex 2 for millions of open and close cycles. The hand is dustproof, drop resistant and impact resistant, and uses anti creep tendon ropes plus full range temperature control for stable operation. A soft, replaceable skin and anti pinch seams improve safety around people.

Applications
- Humanoid robot integration: a human sized, lightweight end effector for humanoids and robot arms.
- Factory handling and assembly: repeated grasping, part transfer and tool use where durability matters.
- Service and household robots: soft skin and anti pinch design for work around people at home or in commercial spaces.
- Manipulation research: back drivable joints and fine force control support grasp studies and teleoperation.
- Custom robot programs: the open development ecosystem allows integration into proprietary platforms.
Who Should Buy the Xynova Flex 2?
The Flex 2 suits robotics integrators, humanoid developers and automation teams who need a dexterous hand that works every day rather than one that only performs in demos. If you want human like dexterity combined with real grip strength and a durability rating built for deployment, this is the Xynova hand to buy.
Which Should You Buy?
| If you need... | Choose |
|---|---|
| A durable hand for daily production or service work | Xynova Flex 2 |
| Fine positional repeatability | Xynova Flex 2 |
| Low weight on the end of an arm | Xynova Flex 2 |
| Transparent force data for AI training | Xynova Prima 1 |
| A higher lifting payload | Xynova Prima 1 |
Before You Buy
- Check the wrist interface: confirm how the Flex 2 mounts to your arm or humanoid and request the mechanical drawing.
- Size for continuous load: plan everyday tasks around the 4 kg continuous rating and treat 12 kg as the peak grasp.
- Plan your software: confirm the control interface and SDK your team will use with the open development ecosystem.
- Stock spare skins: the soft skin is replaceable, so keep spares for high use deployments.
- Order in pairs if needed: bimanual robots need a left and right hand, so confirm handedness when you order.
Frequently Asked Questions
What is the Xynova Flex 2?
The Xynova Flex 2 is a 23 degree of freedom dexterous robot hand that uses a hybrid tendon and direct drive system. It weighs about 400 g and is built for durable industrial and service use.
How much can the Xynova Flex 2 lift?
The Flex 2 has a single hand grasp load of 12 kg and a rated continuous operating load of 4 kg.
What does hybrid drive mean in a robot hand?
A hybrid drive combines tendons with direct drive motors. Tendons keep the fingers light and flexible, while direct drive adds precision and control, giving a balance of compliance and accuracy.
How precise is the Xynova Flex 2?
The Flex 2 offers ±0.1 mm repeatability and force control accuracy down to 0.05 N.
What is the difference between the Flex 2 and Prima 1?
The Flex 2 uses hybrid drive and targets everyday deployment. The Prima 1 is fully direct drive and is designed for research, data collection and AI model training.
