South African warehouses already use automation, but high unemployment creates a difficult balance between productivity, investment and the need to protect jobs. For the cold chain, however, robotics could offer some particular advantages.

The rapid development of warehouse robotics presents South African operators with a difficult question: how far should automation proceed in a country where unemployment remains extremely high?
Logistics specialist Martin Bailey addressed this issue during his presentation at the 2026 SAPICS Conference in Cape Town, comparing South Africa’s position with highly automated economies such as South Korea and Singapore. He noted that Korea and Singapore have around 700 robots per 10 000 employees, while their unemployment rates are below 4% and 2% respectively.
South Africa presents a very different picture, with unemployment at almost 34%. This means the introduction of robots has consequences beyond productivity and return on investment. In South Africa, automation can directly affect employment, making the decision to replace manual tasks with machines considerably more complicated.
At the same time, the financial case for automation can be compelling. Bailey illustrated the potential economics using a humanoid robot costing around R340 000. If the robot could work two shifts and replace two workers costing R15 000 a month each, the theoretical payback period would be about one year.
The calculation depends on a number of assumptions, including the robot’s ability to perform the required tasks reliably and continuously. It also does not necessarily account for maintenance, software, charging infrastructure, integration and supervision.
Nevertheless, it illustrates why warehouse operators are likely to take robotics increasingly seriously. South African facilities are already using conventional automation, including autonomous mobile robots, robotic arms and automated systems for sorting, storage, picking, packing, driving and palletising.
The technology could be particularly relevant to the cold chain. Temperature-controlled warehouses are demanding working environments. Employees working in chilled and frozen facilities can be exposed to low temperatures for extended periods, while cold stores need to maintain high levels of operational efficiency because refrigeration represents a significant ongoing energy cost.
Automation can reduce the amount of manual handling required in these environments while allowing warehouses to operate continuously. Automated storage and retrieval systems, robotic picking, palletising and mobile robots can also improve consistency and reduce the physical demands placed on workers.
For large cold-storage facilities handling high volumes of predictable product movements, these advantages could become increasingly attractive. Automation can also contribute to stock accuracy and traceability. In a cold chain where products have defined shelf lives and temperature requirements, knowing where a particular product is, when it entered storage and when it needs to leave can be critical.
But robotics should not be viewed simply as a replacement for human labour. The more sophisticated the technology becomes, the greater the need for people capable of installing, programming, maintaining and supervising it. The skills required in a highly automated warehouse are different from those required in a conventional facility.
This could create an important opportunity for South Africa if automation is accompanied by investment in technical and digital skills.
The question is also where automation makes economic sense. A large distribution centre with high volumes and predictable product flows presents a very different business case from a smaller cold store handling irregular volumes and a wide variety of products.
The cost of the equipment, integration with warehouse-management systems, maintenance requirements and availability of technical support all have to be considered.
Energy is another consideration for cold-chain facilities. Automated equipment adds electrical loads, while refrigeration remains one of the largest consumers of energy in many temperature-controlled warehouses. Operators therefore need to consider the entire energy profile of an automated facility rather than looking at the robot in isolation.
Nevertheless, the direction of travel is clear. Robots are already part of modern logistics, and their capabilities are expanding rapidly. The emergence of increasingly sophisticated AI-powered machines could accelerate that trend.
Bailey’s conclusion was deliberately cautious. “These are interesting times. Robots are undoubtedly our future, but we cannot say when and to what extent, especially in South Africa,” he said.
For the cold chain, the immediate future is unlikely to involve warehouses populated entirely by humanoid robots. More realistically, automation will continue to develop task by task, with robots taking over repetitive, physically demanding or highly controlled activities while people remain responsible for supervision, maintenance, decision-making and exception handling.
The result could be a more efficient and safer warehouse – but only if the technology is matched to the operation and the wider economic and social realities of the country.
For South Africa’s cold-chain industry, that balance will be particularly important. The pressure to improve productivity and reduce operating costs is not going away, but neither is the need to create sustainable employment and develop the skills required by an increasingly automated logistics sector.
