BionicSoftHand - Soft to Touch, Strong on Grip

Whimsical Intro

Our hands are a marvel of nature, capable of performing a wide variety of complex tasks. From grasping and holding objects to typing and manipulating small items, we rely on them without even thinking. But what if we could replicate this dexterity in machines? How would it work, and would it mean for the future of robotics and human collaboration? Let’s explore the incredible technology behind the BionicSoftHand.

The Power of the Human Hand: A Natural Blueprint

The human hand is an incredible tool, combining strength, fine motor control, and adaptability and what truly sets it apart is the opposable thumb. This feature allows us to grip, manipulate objects, and handle delicate tasks with ease. Replicating these abilities in robotics has been a challenge for years, but the BionicSoftHand is designed to overcome that. Modeled after the human hand, it’s engineered to handle a variety of tasks with precision. With 12 degrees of freedom (DOF) and pneumatic-driven fingers—four measuring 98mm and a smaller one at 79mm—this design brings a level of dexterity that’s hard to beat.

The Mechanics Behind the Magic: Small but Powerful Technology

The BionicSoftHand uses compact technology that integrates valves, sensors, electronics, and mechanical components to mimic the motions of a human hand. It runs on compressed air, operating at 3.5 bar for the gripper fingers and 6.0 bar for the swivel modules. The hand’s flexible bellows imitate human muscles, allowing it to lift up to 4kg. Its silicone "skin" adds flexibility and enhances safety when handling objects. The hand includes a series of sensors: one inertial sensor on the back, ten in the fingers, and fifteen tactile force sensors. There are also fourteen pressure sensors embedded in the airflow plate. This sophisticated sensor system ensures the BionicSoftHand operates with both safety and precision.

Teaching Robots to Adapt

Teaching robots to learn through experience may sound futuristic, but it’s a reality for the BionicSoftHand. Instead of relying on pre-programmed actions, the robot improves over time through reinforcement learning. When rotating a 12-sided cube, the robot hand makes adjustments by recognizing and correcting its mistakes. This approach, called massively parallel learning, allows multiple virtual hands to share data. The hand also uses 24 proportional piezo valves that control airflow making precise movements possible.

Gesture Imitation for Seamless Remote Operation

The BionicSoftHand can also be controlled remotely through gesture imitation. Using a depth-sensing camera, the system can capture the user’s hand movements, which the robot can then mirror. This allows the hand to operate from a safe distance. This functionality is  extremely useful when handling dangerous substances or in harmful environments. Multiple systems can even be controlled at once. As manufacturing becomes more flexible, adaptable grippers like the BionicSoftHand will play an important role in automating complex tasks.

Soft Skin for a Strong Grip

The BionicSoftHand’s structure is built around rubber bellows, covered with a 3D textile. This textile is made from elastic and high-strength fibers, which control where the material expands or restricts movement. The outside of the gripper fingers is elastic, while an internal strap keeps them from stretching lengthwise. This design makes the fingers bend when air fills the bellows. Flexible printed circuit boards are embedded in the fabric, holding the inertial and tactile sensors. These thin circuits are flexible and don’t interfere with finger movement, providing both function and flexibility.

Brief History

Festo Robotics has long been at the forefront of automation, consistently pushing the boundaries of innovation by merging biological principles with engineering. Their venture into robotics gained momentum in the early 2000s with the introduction of bionically inspired designs, setting the stage for revolutionary advancements. One of their breakthrough moments came in 2010 with the launch of the Bionic Handling Assistant, which marked a major step forward in human-robot collaboration.

Building on these foundational successes, Festo unveiled the BionicSoftHand in the 2020s, taking their bionic approach to robotics to new heights. Modeled after the human hand, this advanced robotic hand integrates pneumatic-driven technology with a soft, flexible design to perform tasks that require both strength and precision. With applications ranging from delicate object handling to more complex operations, the BionicSoftHand is a key player in industries that demand adaptability and safety.

Our Perspective

We think the BionicSoftHand is more than just a robotic hand—it represents a leap forward in our relationship with technology.
