Sharpa W02 vs W01: How Has the New Dexterous Hand Changed?

Sharpa introduced the W02 dexterous hand in September 2026 as the next generation of its Wave hand platform. The new model retains a five-finger design while reducing weight and overall size, with 21 active degrees of freedom and tactile sensing across the fingertips, fingers, and palm.

Compared with the W01, which has 22 active degrees of freedom and weighs 1.3 kg according to Sharpa's published specifications, the W02 places greater emphasis on compact construction and lower end-of-arm weight.

For buyers evaluating dexterous hands, the key question is not simply whether the newer model has fewer degrees of freedom. It is whether the changes better match the required manipulation tasks and robot integration constraints.

Specifications are based on the manufacturer's published information. Buyers should confirm the exact version and configuration before comparing quotations.

One of the most significant changes is the W02's lower weight.

Sharpa lists the W01 at 1.3 kg and the W02 at less than 750 g. The company describes the W02 as approximately 30% smaller than its predecessor, although weight and physical dimensions are separate measurements.

A lighter dexterous hand can reduce the load on the robot arm and leave more payload margin for adapters, cables, and other end-of-arm components. It may also make integration easier where the available working space is limited.

However, the benefit depends on the complete system. Buyers should evaluate the robot's payload capacity, wrist loading, center of gravity, and motion requirements rather than treating hand weight as the only selection criterion.

The W01 has 22 active degrees of freedom, while the W02 has 21. A lower degree-of-freedom count does not automatically mean reduced practical capability.

The number of active degrees of freedom describes how many independently controlled movements are available. Real-world performance also depends on finger geometry, joint ranges, actuator design, sensing, and control.

For W02, Sharpa emphasizes a more compact structure and full-hand tactile sensing. The company combines its Dynamic Tactile Array at the fingertips with electronic skin covering much of the fingers and palm.

This design gives buyers another factor to evaluate: the balance between movement, sensing coverage, weight, and system complexity.

The W02 combines two tactile sensing approaches.

Fingertip Dynamic Tactile Array: Sharpa specifies a force sensing range of 5 mN to 30 N and spatial resolution of 1 mm.

Full-hand electronic skin: The manufacturer specifies a force sensing range of 0.1 N to 20 N and spatial resolution of 5 mm.

This arrangement extends contact sensing beyond the fingertips. It may be relevant when an object touches the side of a finger or the palm during a grasp.

When comparing W01 and W02, buyers should confirm the sensing configuration, available output data, update rates, software support, and compatibility with their robot controller. The presence of tactile sensors alone does not guarantee better performance in every application.

The W01 may be worth evaluating when:

• The existing system has already been developed around the W01.

• Its mechanical and software interfaces fit the current setup.

• The required task has been validated with the W01 configuration.

• Replacing the hand would require significant engineering changes.

The W02 may be worth evaluating when:

• Lower end-of-arm weight is a priority.

• A more compact hand is needed for the available workspace.

• Full-hand tactile coverage is important to the task.

• The robot platform can support the W02's interfaces and control requirements.

These are selection guidelines rather than a universal ranking. The better choice depends on the task, integration cost, and confirmed specifications of the supplied configuration.

For either model, buyers should verify the mechanical interface, power requirements, communication protocol, SDK availability, sensor output, and supported control environment.

It is also important to clarify the quoted configuration, included accessories, replacement parts, maintenance process, and delivery lead time. If the hand is being installed on an industrial or collaborative robot, the complete end-of-arm assembly must remain within the robot's load and safety limits.

For customers considering alternative products, the DH-Robotics ADH-5-13 is another five-finger dexterous hand worth evaluating. Its 13 active degrees of freedom and direct-drive architecture differ from Sharpa's Wave design, so a meaningful comparison should consider task requirements and integration compatibility, not only the number of fingers.

The Sharpa W02 represents a shift toward a lighter, more compact five-finger dexterous hand with 21 active degrees of freedom and tactile sensing across a larger portion of the hand. Compared with the W01, the main purchasing considerations are reduced weight, smaller dimensions, sensing coverage, and compatibility with the existing robot system.

Before selecting either model, confirm the exact configuration and test it against the intended task. A practical evaluation of grasping performance, interfaces, maintenance, and total integration cost is more useful than choosing solely by model generation.
