Tesollo Unveils Compact 20-DoF Hand

Tesollo’s 20-DoF hand is shipping—finally, a real do-it-all gripper.

Tesollo has officially commercialized its lightweight, compact humanoid hand—the DG-5F-S—marking a rare moment where a vendor moves from prototypes to a true product for humanoid systems. The device is pitched as a trimmed-down evolution of the company’s flagship DG-5F-M, with a deliberate emphasis on miniaturization and weight reduction to broaden deployment options across varied platform footprints. The DG-5F-S is built on Tesollo’s dedicated gripper actuator technology, and the company argues the redesign directly addresses the “practical requirements repeatedly encountered during real deployments.”

The DG-5F-S is a five-finger, 20-degree-of-freedom hand. In Tesollo’s framing, that 20-DoF figure translates to a richer range of grasping and manipulation motions without inflating the form factor. The project’s branding emphasizes integration-friendly design rather than headline-grabbing numbers; the company points to a wider variety of humanoid platforms as the driver for the new hand’s form and control interface. Tesollo briefings describe the DG-5F-S as a product born from hands-on deployment work, with the goal of making it easier to bolt onto existing arms and torso configurations rather than forcing a full platform redesign for each customer.

In terms of readiness, Tesollo positions the DG-5F-S as a commercial product, not a lab demo. Debuting at CES 2026 and now being marketed as a commercial hand, the DG-5F-S is intended for real deployments with customers rather than isolated test rigs. That status implies a field-ready level of maturity: the hand is designed to operate in real environments, with the expectation of being integrated onto customer humanoid robots rather than being used solely for internal demonstrations. The press and engineering notes reference “dedicated gripper actuator technology” as a core differentiator, suggesting a packaging and control approach optimized for reliability and repeatability in manipulative tasks.

But the rollout is not shy about its boundaries. The official materials do not publish a payload capacity for the DG-5F-S, leaving end-users with an incomplete picture for tasks that require lifting or sustained force. The same omission applies to runtime and power specifications; neither the battery chemistry, capacity, nor charger details are disclosed in the announcement. In practice, that means system integrators must perform their own retention and thermal budgets, especially if the hand will operate under continuous load or in warm environments. Demonstration footage shows smooth multi-joint actuation and natural grasping in controlled settings, but without hard metrics on payload, cycle life, or fault modes, engineers will want to validate the hand against their own task profiles before committing to a full platform integration.

Compared with the prior generation, the DG-5F-S makes tangible progress on integration ease and physical footprint. Tesollo’s release centers on the redesign’s weight reduction and miniaturization, enabling use with smaller humanoid chassis and more compact arm assemblies. The changes are not just cosmetic; they reflect a shift in how the hand interfaces with upper-limb systems, with a focus on reducing mounting complexity and powering all five fingers effectively in tighter envelopes. The DG-5F-M, by contrast, served as the flagship reference for capability; the DG-5F-S is where Tesollo translates that capability into a form factor that can be more readily adopted across a broader family of robots.

Two practitioner takeaways emerge. First, the move to a genuinely compact, 20-DoF hand is a meaningful enabler for mid-size humanoid platforms that previously faced weight or space penalties during tooling and end-effector planning. Second, the lack of disclosed payload and runtime data remains a gating item; for industrial users, grabbing delicate objects is only useful if the hand can also hold its own under load and operate within a known thermal and power envelope. In a market flooded with demo reels, the DG-5F-S’ emphasis on real deployment scenarios and integration-ready design signals a modest, credible step forward—one you can actually audit in field tests, provided you have access to the payload and power specs.
