Welcome, ZWHAND B20!
The ZWHAND B20 is a robotic hand from Shenzhen ZWHAND Technology Co., Ltd., positioned around dexterity and controlled manipulation. Its overall Humanoid.Guide Hand Score is 6 out of 10, placing it in the capable or mature category rather than the highest performance bracket. The score combines a Degrees of Freedom rating of 4 out of 5 with a Strength rating of 2 out of 5. This creates a clear assessment profile: degrees of freedom are the stronger rated attribute, while strength occupies a lower tier. These ratings describe category standing, not a joint count, lifting capacity, or measured gripping force. For readers comparing robotic hands, the distinction matters because dexterity and strength represent different selection priorities. The B20’s assessment favors its degrees of freedom rating without suggesting equally high strength performance. Its overall result provides a useful starting point for comparison, while keeping the separate category ratings visible rather than treating one combined score as a complete technical specification.
The key technical distinction in the B20’s rating profile is the separation between degrees of freedom and strength. A 4 out of 5 rating for degrees of freedom is a positive indicator within that scoring category, but it does not establish precision, repeatability, or suitability for a particular task. Similarly, the 2 out of 5 strength rating should not be translated into a physical load limit. For manipulation research, component evaluation, or robotic hand selection, these scores help organize the questions that matter next. Teams prioritizing dexterity can examine the stronger rated category, while applications requiring substantial gripping force warrant particular scrutiny of strength requirements. The practical value is a clearer comparison framework, not a guarantee of application performance.
The B20 is listed as in production, with an advertised price of USD 6,500 and an option to inquire about pricing. Its manufacturer, Shenzhen ZWHAND Technology Co., Ltd., is based in China, and ZWHAND is described as the hand division of Zhaowei Machinery. The listed weight is 0.6 kilograms. Together, production status, price, and weight give prospective buyers concrete procurement and integration reference points beyond the headline score. The manufacturer’s website is www.zwhand.com. In the broader robotic hand market, the B20 illustrates why a combined rating benefits from being read alongside its individual categories: a capable overall assessment can coexist with a stronger degrees of freedom rating and a more modest strength rating.
