AgiBot OmniHand 3 Dexterous Hand

OmniHand 3 Robotic Hand for Humanoid and Mobile Platforms

AgiBot OmniHand 3 is a robotic hand designed for integration into humanoid platforms, mobile robotic complexes, and service systems. The kinematic scheme has 10 active and 6 passive degrees of freedom, providing high finger mobility, precise object gripping, and complex gesture reproduction. The tactile system contains over 300 sensitive zones distributed across the surface of the fingers, palm, and back of the hand. The sensor array registers physical contact with objects during gripping, holding, and performing complex manipulations.

Advantages of AgiBot OmniHand 3

• Flexible control of finger movements. The kinematic hand encompasses 10 active and 6 passive degrees of freedom, allowing for adaptive finger configurations, precise gestures, and gripping objects of arbitrary shapes.
• Handling objects weighing up to 5 kg. The allowable load is up to 5 kg, enabling the gripping, holding, and moving of objects within this range.
• Touch control on different parts of the hand. Over 300 sensitive elements are located on the fingertips, palm, and back of the hand for accurate registration of physical contact with objects or the operator.
• Contact recognition across the entire hand surface. Simultaneous registration of the tactile data array from all points allows for interaction not only with the fingertips but also with the palm and back of the hand.
• High actuation dynamics. The typical time for fully opening or closing the hand is 0.5 s, optimizing operations with repetitive cyclic gripping.

Kinematics with 10 Active and 6 Passive Degrees of Freedom

OmniHand 3 has 10 active and 6 passive degrees of freedom. Each degree of freedom is responsible for a separate movement in the mechanical structure of the hand. Active degrees of freedom are controlled by drives and execute control system commands. Passive degrees of freedom change position according to joint kinematics and mechanical interaction during hand operation.

This design allows for different finger positions, gesture reproduction, and multiple gripping methods. Thanks to such kinematics, finger positions can adapt to the object's shape during gripping.

Tactile System with Over 300 Sensitive Points

OmniHand 3 is equipped with over 300 tactile elements distributed across the main contact zones of the hand. They register mechanical contact with objects or humans and are located on:

• fingertips;
• palm;
• back of the hand.

This arrangement allows for determining where contact occurs during object gripping or interaction with a human. The tactile system complements finger position data with information about actual physical contact with an external object. The tactile system operates on a one-dimensional measurement principle and has a resolution of 0.1. A separate sensor zone on the back of the hand allows for touch registration beyond the fingers and palm.

Handling Objects Weighing up to 5 kg

AgiBot OmniHand 3 is designed to handle loads up to 5 kg. The hand's design allows for working with objects of various shapes and sizes, changing finger positions according to the object's geometry. This is suitable for gripping, holding, moving, and transferring objects in robotic systems.

Contact Recognition with Humans and Objects

OmniHand 3 registers physical contact with a human or object in different zones of the hand. Touch data is transmitted to the control system and can be considered during gripping, holding, and other contact operations. Sensor zones on the fingers, palm, and back of the hand allow for contact determination at multiple points. The design also includes pinch protection for more controlled contact interaction with humans and objects.

Applications of AgiBot OmniHand 3

• Education and training programs. Used in universities, laboratories, and research centers for studying robotics, kinematics, motion control, and tactile systems.
• Human-robot interaction. Research on physical contact, robotic system response to touch, and the use of tactile data during control.
• Mobile robotics. Installation on mobile manipulators for gripping, holding, moving objects, and performing other operations with a robotic hand.
• Service robots. Working with objects, performing gestures, and contact interaction in robotic systems for auxiliary and service tasks.
• Research robotic platforms. Used as an end effector module for testing control algorithms, object gripping, and tactile interaction.

Integration with Humanoid and Mobile Platforms

OmniHand 3 is suitable for installation on humanoid robotic platforms and mobile manipulators. Before connecting, it is necessary to check the mechanical, electrical, and software compatibility of the hand with a specific robot model. Interfaces CAN FD and RS485 are provided for data exchange. During integration, it is necessary to consider the type of mounting, power parameters, controller compatibility, and software control requirements.
