For decades, robots have been a common sight in manufacturing plants across the globe. From upstream production and assembly applications, welding, fabrication and painting to downstream end-of-line tasks such as case packing and palletizing, robots are tried and true productivity solutions in manufacturing. The applications that they perform share a common thread of precision and repeatability - the sweet spot of historical robotic applications. Any process which calls for the same task to be completed repeatedly, particularly if it is dirty, dull or dangerous, is a prime candidate for a robotic application.
However, as the capability of robotic mobility, vision guidance and control software evolves, so does the ability of robots to function in more dynamic and unstructured environments – functions that are more closely aligned with tasks that are done manually in today’s distribution and fulfillment centers. This new frontier will call for robotic solutions that are capable of performing unpredictable, inexact, not always repeatable tasks, and require a higher degree of spatial and object awareness through use of real-time, adaptive control algorithms. This paper will compare traditional material handling solutions with their robotic counterparts within the distribution and order fulfillment center, and where these solutions might be heading in the future.
Robots, Automation and the Drive Towards a Smarter Supply Chain
The high costs and multiple employee touches associated with product receiving, shipping and order filling in today’s distribution and fulfillment centers provide potential targets for robotic automation.
These functions include: receiving; put away and replenishment; order fulfillment; pack out; and shipping. Let’s take a closer look at how some of these operations have traditionally been handled and then review potential robotic solutions that could assist workflow.

What’s Around the Corner?
Given the increasing velocity of innovation and investment in robotics, we can expect that both cost and complexity of existing robotic solutions will diminish. Scientists and engineers are working on developing low cost, high functionality robots, equipped with high degree of freedom (DOF) arms and highly adaptable grippers. Coupling this with cameras, sensors and sophisticated software will enable robots to “see” objects, “feel” forces and
“understand” tasks. There is a desire to develop robots that replace continuous repetitive tasks and are able to safely interact with individuals to assist them in performing specific tasks done manually today.
When it Comes to Automation Solutions, Consider Robots a Part of Your Plan
Increasing productivity while controlling cost will continue to drive more workflow automation into the supply chain. While not every aspect of the distribution center activity is a candidate for robotic automation, new improvements in robotic technologies will help DC operators understand
and create more efficient workflow areas to remain competitive and maximize profitability. Our best advice is to discuss potential robotic applications with a certified robotic material handling integrator
partner, and discern how and when the best time is to consider deployment of robotic solutions.
