ZWHAND B20

One linear motor per joint, twenty joints, about 600 g: the third-generation ZWHAND hand unveiled at CES in January 2026 is listed here as the B20, a designation that comes from secondary sources since the CCTV report shows the hand without a name and the maker's website in September 2026 already mentioned a newer B21.

Fingertip force rose to 15 N, the core transmission was tested for more than 500,000 cycles and the volume shrank by 48 percent compared with the previous generation. Sensing combines an electronic skin with an algorithm that fuses force and tactile data. Dimensions of 195 x 85 x 37 mm appear only in secondary sources. Payload, interfaces, supply voltage and sales status are not published; price on request.

Intended uses span humanoids, research and industry, and buyers should ask the maker which revision is current. With twenty direct-driven joints the B20 sits next to the Korean HX5-D20 and the modular Gaia Hand 20 at noticeably lower weight; within the family it follows the seventeen-joint ZWHAND A17.
