A June • Some of the industry's top manufacturing 2019 report by Oxford Economics suggests regions are struggling to attract production that by 2030, up to 20 million manufacturing workers. One way to address this is through jobs worldwide could be replaced by robots— greater use of automation, particularly equivalent to 8.5% of the global robots, to help fewer people work more manufacturing workforce. Furthermore, the productively and more safely report found that people displaced from • Automakers in emerging markets in manufacturing jobs would find that particular must carefully weigh up the need comparable roles in the services sector have to offer employment to lower skilled workers also been impacted by automation and in poor local economies with the need • However, Oxford Economics also found that for high degrees of flexibility, repeat increasing automation will boost productivity accuracy, quality, speed and safety and economic growth, and “lead to the • In developed markets, such decisions focus on creation of new jobs in yet-to-exist the need to accommodate an ageing workforce industries” • Automakers are seeking to combine rather • A common theme in discussions about than replace the strengths of humans with increasing automation in vehicle production the strengths of robots. Humans are good at is the need for robots to assist, not replace, reacting quickly to unexpected incidents, the existing human workforce; where once while robots excel at dangerous, repetitive automation was seen as a replacement for and strenuous tasks humans, now it is widely seen as an enhancer • Collaborative robots (cobots), which can of human labour, taking on the so-called 3Ds physically interact with humans in a shared of manufacturing—work that is dirty, workspace, enable automakers to react to an dangerous and dull industry increasingly driven by consumer • Indeed, the much-anticipated lights-out demands for more customisable vehicles. factory—an entirely automated assembly Global robotics manufacturers have line—may never be fully realised in the facilitated this evolution by developing automotive industry.

The days of plants dedicated to one product are waning, and While it may not always be normalcy for the automotive industry will be “the answer to the challenges defined by uncertainty and frequent change for the foreseeable future. facing automakers, there is Amid this transformation, one of the no question that robots are industry’s biggest helpers is likely to be pivotal in the automotive robotic technology, and its expanding capacity to collect, interpret, and act upon industry’s efforts to reems of real-time data. As the technology introduce flexibility and and expertise evolves to produce manufacturing and assembly robots that are agility into its production lighter, more agile and precise than ever before, they are more frequently found routine working side by side with humans and other robots, taking over repetitive tasks or assisting with logistics and materials handling. In fact, one of the most fruitful automakers the kind of flexibility necessary to areas to automate is logistics, including introduce new models or to switch models with unloading trucks, commissioning and a minimum of down time and a maximum of selecting parts, the transportation of parts, value-added work. A growing percentage of and the collection of bins and containers. factory robots can be redeployed today after simple reprogramming. Like their human No longer the monuments to over-engineering counterparts, many have the capacity to ‘learn’ and complexity that they once were, the latest on the job, and to move from task to task on robotic technologies increasingly offer their own, in some cases. Research by Automotive World 1 Special report: A fresh look at robots in vehicle manufacturing Driverless bots Autonomous mobile robots (AMRs) are prime examples of the new autonomy that bots are demonstrating within the plant. AMRs can Autonomous mobile robots navigate their way through a warehouse, “ unload a truck, or move products to the point (AMRs) are prime of use or warehouse space, relying on elaborate sensors and their capacity to learn from examples of the new humans. They allow producers to circumvent autonomy that bots are the hurry-up-and-wait mentality of many assembly lines and reserve their human demonstrating within the workforce for more value-added tasks. plant.
