Soft robotics brings flexible, adaptable automation to medical technology and industry – safer, more precise, and more cost-effective than rigid robotic systems.
Imagine a robot that isn't made of steel and rigid joints, but grips softly like an octopus. That holds delicate objects without crushing them. That adapts to unpredictable shapes instead of stubbornly following a pre-programmed path. That's exactly what soft robotics is – a technology that is currently fundamentally changing the rules of automation.
While traditional industrial robots have been working in isolated cages for decades, soft robots bring an entirely new quality: adaptability, safety, and precision in areas that were previously barely automatable. Particularly in medical technology and industrial applications where flexibility determines success or failure, the enormous potential of this technology becomes evident.
The difference between conventional robots and soft robotics is fundamental. Traditional robots work with rigid components, electric motors, and precise but inflexible motion sequences. They are perfect for repetitive tasks in controlled environments – but they reach their limits as soon as variability comes into play.
Soft robotics, on the other hand, uses compliant materials such as silicone, soft polymers, or even biocompatible substances. Movement is often controlled by pneumatic or hydraulic systems that enable fluid, organic motion. The result: robots that can grip like a human hand, that snake through tight spaces, or touch delicate tissue without causing damage.
These characteristics make soft robotics the ideal solution for environments where safety, adaptability, and gentle contact are critical – from medical diagnostics to handling fragile components in production.
In medicine, rigid robotic systems quickly reach their limits. The human body is not a standardized workpiece – every anatomy is unique, tissue reacts sensitively, and precision here often means millimeter-level work under difficult conditions.
Soft robotics opens up entirely new possibilities here. Soft grippers can be used in minimally invasive surgery, for example, where they navigate through narrow body openings while gently manipulating organs. Their compliance significantly reduces the risk of tissue damage – a decisive advantage over rigid instruments.
Flexible robots also show their potential in rehabilitation. Exoskeletons made of soft materials support patients during movement therapy without unnecessarily straining the joints. They adapt to natural movement patterns while providing the necessary assistance – a balance that is hardly achievable with conventional technology.
For medical device manufacturers, this means they can develop solutions that are not only safer but also more flexibly deployable. This reduces development costs for specialized variants and opens up new markets that were previously technically inaccessible.
Beyond medicine, soft robotics also demonstrates impressive strengths. In industrial production, there are numerous situations where rigid automation reaches its limits: when handling sensitive electronic components, sorting irregularly shaped objects, or working in tight, unstructured spaces.
A classic example: the food industry. Here, soft, unpredictably shaped products such as baked goods, fruit, or meat often need to be gripped and moved. Conventional robot grippers frequently fail here – they are either too rough or cannot adapt sufficiently. Soft grippers, on the other hand, enclose objects gently and securely without damaging them.
The situation is similar in electronics assembly. Sensitive components such as displays, chips, or flexible circuit boards require precise yet gentle handling. Soft robotics enables automation here that previously had to be done manually – with corresponding efficiency gains.
New perspectives also open up in logistics and packaging. Flexible robots can grip and sort a wide variety of objects without having to develop new grippers for each product variant. This saves changeover times and makes production lines significantly more adaptable.
At first glance, soft robotic systems seem like an expensive specialized solution. But the reality is different – especially for companies that need flexible automation.
The first cost advantage lies in safety. Soft robotics systems can often be operated without elaborate protective enclosures because they pose no injury risk upon contact with humans. This saves not only investment costs but also space in production – a factor that can be decisive especially with limited space capacity.
Second, soft robots reduce the need for customized tools. A flexible gripper can handle a variety of different objects, while rigid systems require their own end effector for each variant. This means less development effort, shorter changeover times, and more flexibility during product changes.
Third, they reduce the reject rate. Especially with delicate products, handling that is too rough leads to damage and rejects. Soft robotics minimizes this risk through its inherent compliance – an advantage that is directly reflected in the cost balance.
The integration of new technologies often fails due to complexity. Soft robotics has a decisive advantage here: many systems are modularly designed and can be integrated relatively easily into existing production environments.
A typical entry point begins with analyzing critical process steps – areas where manual work dominates because automation has not worked so far. These can be assembly steps where flexible parts need to be joined, or quality inspections that require gentle handling.
Modern soft robotics solutions often work with standardized interfaces and can be connected to common robot platforms or collaborative robots (cobots). This means companies do not have to rebuild their entire infrastructure but can deploy soft components strategically where they provide the greatest added value.
Programming has also been simplified. Many systems work with intuitive teach-in procedures or use sensor-based controls that automatically adapt to different objects. This lowers the entry barrier and makes the technology attractive even for operations that do not have robotics specialists on their team.
As promising as soft robotics is – the technology is still at the beginning of its development. There are challenges that must be solved before it becomes widespread.
One of the biggest hurdles is durability. Soft materials are subject to wear, especially with frequent movement or contact with rough surfaces. While rigid robots can be in use for decades, soft components need to be replaced much more frequently. Research is working intensively on more durable materials and smarter designs here.
Precision is also a challenge. Soft systems are naturally less stiff and therefore harder to position exactly. For many applications, this is not a problem – but in areas where micrometers count, rigid systems are still superior. Sensors and adaptive controls can provide a remedy here, but are technically complex.
Finally, there are regulatory questions, especially in the medical field. New robotic systems must go through extensive approval procedures before they can be used on patients. This slows market introduction and increases development costs – a factor that manufacturers must factor in.
Development in soft robotics is progressing rapidly. What is still considered experimental today will be standard in a few years – at least in certain application areas.
In medical technology, it is expected that soft robots will increasingly be used in minimally invasive procedures. Surgical systems will become smaller, more flexible, and more precise. In parallel, rehabilitation robots and care assistants will be further developed – a market with enormous growth potential given demographic change.
In industry, soft robotics will primarily prevail where flexibility and product variety are required. The combination of soft grippers and intelligent sensors will enable new degrees of automation – even in areas that today are still considered "too complex."
It will be crucial how quickly the technology becomes more cost-effective and robust. The more standard components become available and the simpler integration becomes, the faster soft robotics will evolve from a niche topic to the mainstream.
For operations facing the question of how to make their automation future-proof, soft robotics is a serious option. Especially when rigid systems reach their limits – whether in product variety, handling delicate goods, or human-robot collaboration.
The entry does not have to be large. Many providers offer pilot projects or modular solutions with which companies can gain initial experience before making larger investments. It is crucial to understand early on where soft automation creates value in one's own process – and where classic systems remain the better choice.
One thing is clear: soft robotics will not replace all existing automation solutions. But it significantly expands the spectrum of possibilities – and makes automation possible where it has not worked before. For companies that want to produce flexibly, efficiently, and with a future orientation, this is an opportunity they should not ignore.
