Tesollo Ships Its 20-DoF Humanoid Hand for Real-World Use

Twenty DoF in a palm-sized hand—Tesollo's DG-5F-S just went commercial.

Tesollo Inc. has announced the commercial availability of its lightweight, compact humanoid hand—the DG-5F-S—bending the company’s own design philosophy toward easy integration rather than loading the hand with ever-tighter benchmarks. The DG-5F-S is a redesigned member of the DG-5F family, built around Tesollo’s dedicated gripper actuator technology and aimed squarely at real deployments rather than showroom demos. In a CES 2026 reveal, Tesollo showed the DG-5F-S side-by-side with a 15-DoF variant, underscoring the family’s range: five fingers, multi-jointed architecture, and a total of 20 DoF for the flagship S model.

The company positions the DG-5F-S as a practical upgrade over its flagship DG-5F-M, with a strongest emphasis on miniaturization and weight reduction to broaden how and where the hand can be mounted on humanoid platforms. The two-variant presentation at CES 2026—20-DoF for the DG-5F-S and 15-DoF for the companion model—illustrates Tesollo’s design philosophy: more joints for dexterous manipulation, but in configurations that can adapt to different robot wrists and forearms. Tesollo’s description emphasizes integration-friendly geometry and the kinds of constraints real deployments have forced manufacturers to confront: space, cabling, mounting tolerances, and the need for predictable, repeatable grip in varied environments.

What this means for the broader humanoid market is a shift from “one hand fits all” demos to modularity that speaks to actual platform goals. The DG-5F-S is described as five-finger, a 20-DoF multi-jointed holster of motion designed for precise grasping and manipulation—traits that matter when robots are expected to handle everyday objects with varying shapes and fragilities. Tesollo asserts the design supports a broader array of mounting options, enabling more flexible integration across different humanoid bodies and toolchains.

From a readiness standpoint, the press cadence around “commercialization” and CES 2026 positioning signals a field-ready product rather than a purely lab demonstration. In humanoid robotics, that distinction matters: vendors that ship hardware for system integrators must prove reliability, repeatability, and a predictable control interface in real-world environments. Tesollo’s claim to commercialization implies field deployments will soon multiply, with users evaluating the hand across lab benches, factory floors, and service robots alike.

Still, important details remain under wraps. The published specs reveal the DoF counts and the five-finger, 20-DoF architecture, but the company did not disclose payload capacity, torque per joint, or runtime figures for the DG-5F-S. The absence of these numbers matters for engineering planners who must match the hand’s capabilities to grippers on armatures, end-effectors, or tool interfaces. Without payload and power data, engineers are left to infer from the emphasis on miniaturization and the phrase “compact and lightweight” how the DG-5F-S will perform under continuous operation, how heat management will be handled, and what kind of batteries or power packs are supported in fielded configurations.

Two practitioner realities stand out. First, higher DoF generally improves dexterity but raises control complexity, power draw, and potential for dynamic instability in unstructured tasks. Tesollo’s 20-DoF design suggests a capability to negotiate more nuanced grasps, but the real-world payoff depends on the control stack, sensor fusion, and feedback latency—the kind of details the company will need to publish alongside field-ready units. Second, the emphasis on integration indicates a push toward standard mechanical interfaces, cables, and electronics that make the DG-5F-S easier to drop onto existing humanoid wrists. If Tesollo can provide robust mounting templates and a predictable control API (for example, ROS-compatible interfaces or turnkey motor drivers), that will shorten the path from bench to robot.

Industry watchers should also note where this sits relative to prior generations. The DG-5F-M remains the benchmark in terms of a more capable, heavier hand with higher regulatory or production constraints; the DG-5F-S’s selling point is its compactness and weight, expanding the number of humanoid platforms that can carry a hand without renegotiating entire arm topologies. If the DG-5F-S delivers on its promises of easy integration and reliable manipulation, Tesollo could reframe the early-stage costs of humanoid manipulation—particularly for service robots and mid-market research platforms.

What to watch next: official payload and torque specifications, runtime and charging requirements, and any published real-world demonstrations of the DG-5F-S in varied tasks (delicate object handling, uneven surfaces, and dynamic grasp changes). Also note any announced software updates or developer kits that unlock broader control capabilities. Until those details surface, the DG-5F-S stands as a promising step toward truly plug-and-play dexterity in humanoids, with the 15-DoF sibling variant hinting at a broader product family designed for different platform footprints.
