Selected Product Technical Facts
- Identity and intended tasks: The supplier describes a 23-degree-of-freedom biomimetic hand with multimodal sensing, adaptive grasping, slip detection, compliant reflexes and hybrid force/position control for humanoid manipulation. These are official capability descriptions, not verified integration with particular workpieces or third-party arms. The active/passive split is not inferred. Chinese page, English page.
- Source-reported performance: "400 g lightweight palm" describes the palm, not total hand mass. The page states approximately two fist-clench/extension cycles per second, repeatability written <=+/-0.1 mm, force-control accuracy stated as achievable at 0.05 N, single-hand grasping load 12 kg, and rated sustained-operation load 4 kg. Common test definitions, posture, service-life and thermal conditions are not supplied. The grasping load is not assigned to individual fingers, and the "one million opening/closing cycles" claim is not treated as a per-unit guarantee. Product page.
- Mechanical, electrical and developer information: Replaceable flexible skin and an open developer ecosystem are described, but this record does not supply a mounting flange, total hand envelope/mass, power/current, bus/pinout, API, SDK or specific ROS 2 versions. The accessible download-center page in the reviewed record contains an introduction, not a verifiable Flex 2 datasheet/manual with a matched revision. Obtain official documents for the quoted hand side and hardware revision.
- Model boundary: Prima 1 is a different, direct-drive product. Its 22 DoF and 0.08 s opening/closing figure are not Flex 2 specifications. Prima 1, Flex 2.
Company Integration & Application Notes
The reviewed record contains three full technical blocks (Flex 2, PR64-110-500 and PRM10-20-34-150-F) and supplemental facts for Prima 1, PR43-120-600-HB and PRM10-20-18-200-F. The other seven profiles identify listed models and purchasing checks without detailed parameter sets. Table columns, hand models, continuous/peak ratings and dimensional units must not be merged to fill gaps.
The supplier describes Flex 2 hybrid force/position control and multimodal perception, plus actuator-series host software/APIs, without exact-model electrical levels, protocols/registers, SDK/ROS 2 versions or mounting drawings in this record. This does not establish direct interconnection between Flex 2, PRM10, PR joint modules or third-party arms. Flex 2, rotary, linear, download center.
Select exact part numbers, hand side/revision, continuous/peak load, thermal management, power margin, flange, controller and safety circuit. Agree task-level repeatability, force-control, grasp-load and life-test acceptance methods. Unpublished fields remain subject to supplier documentation, not substituted by patents, registered activities or sibling specifications. Company-history harmonic-series and unnamed tendon-hand references do not establish orderable models or justify interpreting the PRH prefix as a transmission type. Official overview.
Before You Evaluate or Order
- Confirm hand side, revision, complete hand mass/envelope and the active/passive breakdown of the stated 23 DoF; the 400 g palm figure is not total hand mass.
- Request official flange/drawings, power/current, pinout, protocol, API and supported SDK/ROS 2 versions for the delivered configuration.
- Agree load and thermal/duty-cycle tests distinguishing 12 kg grasping from the 4 kg rated sustained load, with defined force-control/repeatability conditions.
- Define endurance and sensing acceptance criteria without treating the one-million-cycle claim or other hand models' results as a per-unit guarantee.
These points require confirmation for your intended purchase and application. Missing public information does not imply a product deficiency.
