What does the future hold for robotics?

The robotics revolution is upon us. It has long been the topic of sci-fi thrillers, but now it has arrived, it looks very different to the way we envisioned it. Mechanical men don't march among us, in fact robots are mainly used in industry and they have only just been permitted to operate outside a robot cell. Graham Mackrell, managing director of precision gearing expert Harmonic Drive UK explores what a robotic future really looks like.

Research published by analyst firm Gartner has predicted that one in three jobs will be automated using robotics or software by 2025. A recent report from International Data Corporation reinforces these findings, claiming that the robot market is set to boom in the next three years, growing at a CAGR (Compound Annual Growth Rate) of 17%.


For decades robots have performed a multitude of pick and place functions in many industries that would have previously been filled less efficiently by human workers. Despite market growth and continued adoption, these robots have not rendered human workers obsolete. In fact, the two coexist through collaborative robotics - the latest trend in industry.

For example, surgical robots rather than replacing surgeons, enable them to perform complex procedures with high accuracy. The result is a safer operation and surgeons who are able to work further into old age, thanks to increased steadiness and precision provided by robotics.

Before robots can be implemented in other sectors of industry and trade, health safety standards need to be put in place. The British Automation and Robot Association (BARA) states that the only way to ensure safety in robotic workplaces is to "exclude people from the robot working area". Not only would this prove difficult in many non-factory settings, it is also counterproductive for developments in robotics. Rather than separating humans and robots to prevent the risk of harm, we should be looking to construct robots that are safe to use alongside workers.

Fortunately, the robotics industry has been working towards realising the vision of collaborative robots for some time now. In 2013, the first safety standards for collaborative robotics, ANSI/RIA R15.06, were published, signalling a period of change for industry.

More recently, the ISO/TS 15066 standard was published in March 2016. It specifically outlines guidance and requirements of collaborative industrial robot systems. This was dubbed a "game changer for the industry" by Carole Franklin, secretary of ISO/TC 299/WG 3, as up until its release "robot system suppliers and integrators only had general information about requirements for collaborative systems. [ISO/TS 15066] gives specific, data-driven safety guidance needed to evaluate and control risks."

As more industries begin to adopt collaborative robotics, we will undoubtedly see the release of even more standards to govern them in new sectors. Robot manufacturers will be under constant pressure to maintain high levels of reliability and repeatability, both in the software used for programming robots and the components they are made with.

Reliability, repeatability and payload form a holy trinity of robotics requirements. Because collaborative applications require robots to operate at high speeds and in the company of workers, it is crucial that the internal components provide consistent performance. In particular, precision gears that allow robots to move to exact measurements and stop without delay and zero backlash are particularly important for the future of robotics.

If a surgical robot is unable to operate with absolute precision, it can put patients at risk during the surgery. Safety can be guaranteed by using robotic gears, such as our HFUC-2UH series, that offer repeatable peak torques and are lightweight and compact, enabling the robot to be both nimble and reliable.

Likewise, robots in handling applications rely heavily on spatial awareness and movement. Cameras are often used to simulate vision, but these must offer a high quality image to be effective and prevent both harm to workers and inventory pile-up. In regards to safety, the robot must also have the capacity to react quickly to a human presence.

A robotic future does not have to be a concerning concept as long as manufacturers do not cut corners on components. By ensuring a consistent performance, humans and machines can work side by side without worry.

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.
