Robots are becoming more and more popular as automated replacements for filling low-skilled jobs. While robotic assistance in labs and factories has been commonplace for some time, but robots are soon to be even more widely in household use in the coming years. But for this to happen, more flexible materials are necessary for safer collaborative work alongside humans and delicate tasks usually performed by humans, such as picking fruit and vegetables or performing minor surgeries. 


Soft, Flexible Materials

These activities require a level of dexterity which the current models of robots cannot achieve, so new materials which are softer, more flexible, described as ‘jelly-like plastics’, are being developed as a solution to many challenges faced by using robots. They are also cheaper and easier to produce, as they can be 3D printed.

Such dexterous robots are able to manipulate fragile objects carefully without damaging them, while being much safer for humans to work with/around in factory environments, for example. 

This is making huge progress in the agricultural sector, as fruits and vegetables can be efficiently picked and placed securely. However, the delicate nature of the materials combined with the very smooth gripper surfaces to prevent bacteria/fungus growth (which need porous surfaces) these robots are much more vulnerable to cracks, rips, and other damages.

Consequently, these next generation robots are somewhat impractical for real-world use, until recent advancements in self-healing robotic technology have made headway.



Funded by the EU for 3 million euro ($3.36 million), the Free University in Brussels (Vrije University of Brussels or VUB) has been working with the University of Cambridge, the Ecole Supérieure de Physique et de Chimie Industrielles (ESPCI) in Paris, the Swiss Federal Laboratories for Materials Science and Technology, and the Dutch polymer manufacturing firm SupraPolix. 

Dubbed the ‘SHERO’ (Self-Healing Soft Robot) project, researchers at VUB have been developing robotics made from flexible plastics that have the ability to detect their own damage and make repairs without the need for human intervention. 

David Walker, a tech blogger at Writinity and Last Minute Writing, writes: “Machine learning has been used throughout this ground-breaking process to design and integrate self-healing polymers which can create new bonds autonomously to repair damages.” Sensor fibers are embedded into these polymers, which can then detect the location of the damage and begin to actuate the healing process. The robots are then able to create new bonds in the damaged location and, depending on the location and the extent of the damage, can take anywhere from just a few minutes to a week (at room temperature) to patch themselves up. 

As Jennifer Vanhoy, an IT expert at Draftbeyond and Researchpapersuk, says, “This industry-changing development means the process of repairing damage to robots is entirely automated, removing the need for heat-activated systems via human intervention (through touch).”


A Cheaper, Safer, Sustainable Solution

The cost of robot repairs and replacements is incredibly high, so the introduction of self-healing technology is not only game-changing, but can help to reduce the need for time-consuming, complex, and expensive repairs. It also has implications for sustainability, as robots will have to be replaced with new models less often, since they can perform standard maintenance independently and autonomously.

Self-repair mechanisms in robots also means they are less of a risk to the humans that may be working with or near them, since they are unlikely to cause any real damage due to their gentle, flexible nature. This makes work environments with increasingly high populations of robotic ‘workers’ much safer for human workers and the products.

By developing soft, safe materials embedded with polymers which can sense and locate damages and trigger the healing process without human interference, robots traditionally found as automated workers in factories and labs will soon begin to move into more environments, such as agriculture, and into the average household. Users or owners of such robots will avoid the need to seek out costly repairs for damages sustained and can instead take advantage of this safe, sustainable alternative, putting this at the forefront of developing a new generation of robotics.

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow Introduces 6th Generation Camera Link Frame Grabber: The Axion

BitFlow has offered a Camera Link frame grabbers for almost 15 years. This latest offering, our 6th generation combines the power of CoaXPress with the requirements of Camera Link 2.0. Enabling a single or two camera system to operate at up to 850 MB/S per camera, the Axion-CL family is the best choice for CL frame grabber. Like the Cyton-CXP frame grabber, the Axion-CL leverages features such as the new StreamSync system, a highly optimized DMA engine, and expanded I/O capabilities that provide unprecedented flexibility in routing. There are two options available; Axion 1xE & Axion 2xE. The Axion 1xE is compatible with one base, medium, full or 80-bit camera offering PoCL, Power over Camera Link, on both connectors. The Axion 2xE is compatible with two base, medium, full or 80-bit cameras offering PoCL on both connectors for both cameras. The Axion-CL is a culmination of the continuous improvements and updates BitFlow has made to Camera Link frame grabbers.
