Agibot Omnihand Pro 2025

Agibot Omnihand Pro 2025

Positioned above entry-level grippers and classroom hands, the Pro variant emphasizes tactile perception, serviceable mechanics, and a developer-first software stack (including ROS 2 drivers) to accelerate policy learning and real-world integration.

The platform seeks to balance human-like dexterity (precision pinch, lateral key grip, power grasp, and in-hand reorientation) with industrial practicality (IP-rated covers, field-swappable tendons, standardized control buses). Typical customers include universities, R&D groups, systems integrators, and teams piloting bimanual manipulation in logistics and services.

Design and Features

Anthropomorphic geometry

OmniHand Pro 2025 adopts a human-inspired layout with an opposable thumb, three identical central fingers, and a supportive little finger. Joint centers and phalange lengths are optimized for everyday objects—bottles, cartons, tools, appliance knobs—at bench height, enabling natural prehension without bespoke jaws.

Tendon-driven actuation with underactuated compliance

The hand uses tendon transmissions routed over low-backlash pulleys. Key phalanges are differentially coupled for passive shape adaptation, while high-dexterity degrees of freedom (e.g., thumb opposition, index distal) remain independently driven. This hybrid design delivers secure wraps on irregular items and fine fingertip placement for thin or deformable objects.

Integrated tactile perception

Each fingertip incorporates multi-cell pressure taxels for contact onset and grip estimation; micro-vibration sensing supports incipient-slip detection. A 6-axis palm force–torque option is available for whole-hand control, delicate handovers, and grasp stability analysis. The controller fuses touch, joint torque/position, and (when fitted) palm F/T to maintain stable, low-force grasps.

Interactive feedback and HRI

LED indicators on the shell communicate contact, slip, and overload states. When paired with supported teleoperation hardware, the Pro 2025 can relay vibrotactile cues back to an operator, shortening the loop from demonstration to deployable skills and reducing over-tightening during data collection.

Serviceability and modular fingertips

Color-coded tendon paths sit behind gasketed inspection covers for in-field replacement. Snap-in fingertip pads (high-friction rubber, ESD-safe silicone, textured polymer) and screw-in inserts (studs, hooks, stylus tips) enable quick reconfiguration across tasks without redesigning end-of-arm tooling.

Technology and Specifications

• Degrees of Freedom (typical):

  • Thumb: 4 DoF (incl. opposition)

  • Index/Middle/Ring: 3 DoF each

  • Little: 3 DoF

  • Total controllable DoF: up to 16–19 (mix of independently driven and underactuated joints)

• Actuation: compact BLDC/coreless micro-drives with compliant tendon routing; tuned elasticity provides series-like compliance for safer human-proximate work.

• Peak fingertip force (per digit): 15–25 N (config-dependent).

• Aggregate power-grasp force: 35–60 N sustained.

• Position fidelity: sub-degree joint sensing; fingertip repeatability <0.5 mm in calibrated workspace.

• Tactile sensing: multi-cell fingertip arrays (standard density) with slip detection; high-density gel pads optional.

• Palm sensing: optional 6-axis F/T for whole-hand force control.

• Materials: aluminum sub-frame, polymer/fiber-reinforced shells; ESD-safe pads available.

• Ingress protection: IP42–IP54 options (light dust/splash).

• Mass (hand-only): ~650–950 g by sensor loadout.

• Power: 24 VDC; <80 W peak during firm power grasps.

• Thermal: passive heat spreading; onboard temperature monitoring.

• Interfaces: EtherCAT or CAN-FD for real-time control; USB-C service; industrial M12 harnessing optional.

• Software: ROS 2 drivers, C++/Python SDK, URDF models, grasp planners, and example reflex policies (grip-tighten, micro-roll, re-grasp).

• Mounting: ISO-style wrist flanges for common cobots/arms; optional quick-change coupler.

Control architecture and reflexes

A supervisory controller fuses tactile and proprioceptive signals to drive contact-aware reflexes:

• Grip-tighten on incipient slip to maintain hold without large force jumps.

• Micro-roll to “seat” objects using small finger rolls rather than squeezing.

• Re-grasp when shear forces exceed thresholds, reducing drop risk.

These low-level behaviors are deliberately simple and composable, allowing high-level policies (scripted tasks, imitation learning, vision-language-action plans) to remain portable across objects and scenes.

Applications and Use Cases

Manipulation research and robot learning

The Pro 2025 supports imitation learning from teleoperation, reinforcement learning with tactile rewards, and contact-rich benchmarks (in-hand rotation, cap unscrewing, bimanual assembly). Tactile cues help detect stable vs. unstable grasps for better transfer from simulation to real.

Logistics and light manufacturing pilots

On collaborative arms or AMR-mounted manipulators, the hand tackles mixed-SKU picking, kitting, and packaging—including deformable goods and film-wrapped items. Underactuated compliance accommodates irregular geometry without custom parallel jaws.

Service robotics and humanoids

Human-like geometry enables appliance knobs, drawer pulls, handles, utensils, door latches, and person-to-robot handovers. LED state cues aid supervised public demos and semi-autonomous trials in reception or retail.

Education and workforce training

Universities and polytechnics use the Pro 2025 to teach grasp taxonomies, tactile fusion, reflex design, ROS 2 manipulation, and safety. Modular fingertips and accessible routing minimize downtime in teaching labs.

Healthcare and assistive R&D (non-clinical)

For research on activities of daily living (ADL), tactile sensing assists fragile-object handling and safe handovers under supervision (not a medical device).

Advantages / Benefits

• Contact-aware dexterity: Multi-zone tactile arrays with slip detection deliver gentle, stable grasps on soft, glossy, or irregular items.

• Rapid skill authoring: Interactive LEDs and optional haptic cues shorten teleop training loops and reduce operator error.

• Deployment-ready mechanics: IP-rated covers, field-swappable tendons, and shock-tolerant shells balance lab-grade sensing with real-world durability.

• Developer-first stack: ROS 2 drivers, grasp libraries, and real-time buses streamline integration with cobots, AMRs, and humanoids.

• Modular fingertips: Swap friction, ESD behavior, or textures in minutes—no redesign of EOAT.
