warehousing & logistics


autonomously move materials without the need for physical guides or markers. The AMR’s main components include a controller, computing unit, battery, motors, sensors, lights, sounds and camera. A simple trial of one or two AMRs is quick to


deploy, and answers in practice the many pressing automation questions, such as ‘How do robots work alongside people?’, ‘Where can they be used?’ and ‘How often do they need charging?’. Workers quickly discover that robots


travel at the same speed as a human walking. Lights flash when an AMR is about to move, and most have indicators to show if they are turning left or right at the end of the aisle - which is more than can be said for warehouse workers! While robots will typically operate for at least one full shift without needing to be charged, they are programmed to return to the charging station before they run out of power. They are also programmed to complete the current task before doing so, to avoid vital goods being stuck in the charging area, and will not start a new task without sufficient charge. More sophisticated programming can also use opportunistic charging - where the robot has a need to pause for short times during operations, therefore, adding a charger connection in this location allows the AMR to top up its power.

So where might an AMR work best? Essentially, robots can minimise the time spent walking around the building – something that is particularly valuable within a warehouse environment. Staff can spend more time

picking, simply taking the goods to the robot at the end of the aisle. The robot can then take a number of items to the next location, such as packing. In a manufacturing setting, a robot could take the finished goods to the stores, or bring raw parts from stores - after they have been manually quality checked by a skilled employee. This approach allows the business to make


the best use of all resources. Use people in their areas of expertise, such as accurate, fast picking and quality checking; while using robots to complete repetitive tasks such as moving goods around the warehouse quickly and safely. For an initial trial, there is no need for


direct integration into the IT system. Information about what tasks to complete and when it can be provided by a small software link or a piece of hardware that identifies when an item is ready to be collected. It is a straightforward process to show the business - and employees - how and where automation and people can work side by side.


Low-Cost AutomAtion


Obviously, the more a business automates, the greater the efficiencies gained. But even the smallest automation will deliver improvements. Adding a robot or two can allow a business to reallocate staff to more valuable areas and help to reduce the pressure on recruiting warehouse


operatives. With confidence


in the technology and a real understanding of automation in practice, it is far easier for a business to consider where and when automation could fit. And for those companies still concerned about the level of investment, growing numbers of robots are now available on a rental model – even by the hour. The concept of ‘robot as a service’ is


hugely compelling for industries, such as logistics and manufacturing, where peaks and troughs in demand are hard to manage with a permanent workforce. With a couple of robots parked up, charged and ready to go, a business can be 100 per cent in control of the cost, paying only for the hours used but with confidence that the capacity is available to cope with peaks in demand. The key is to build that confidence,


embark on a small scale trial and understand how AMRs work in any business, of any size, to create a successful, efficient hybrid workforce that can scale up and down in line with demand.
