3 must-have robotic technologies in today’s parcel distribution

The development of robotic technology for parcel distribution has been under wraps for some years now. But that’s all starting to change as we begin to integrate a number of robotic technologies in today’s modern CEP business.

Robotics are reshaping and redefining automation. In this article we explore three robotic technologies that can help CEP businesses keep pace with modern sortation demands. 

Cracking the code to the robotic brain 

But before we get into the technologies, let’s discuss why the development of robotic technology for the CEP logistics hub has been so slow. 

Although much of the technology needed to implement robots had been developed, no robotic intelligence or robot grip had been developed that was versatile enough to handle the variety of parcels that distribution centres receive in real life. The objective of robotic intelligence is to essentially digitise human intelligence. And that was the problem: developing the right brain for the robot

Today, however, we are seeing major shifts in digitising human intelligence. Experiments and trials are cracking the code to applying as much intelligence as possible. And breakthroughs are being made. 

Let’s take a look at the three technologies.

1. Robotic tipping arms

A prime example of the emerging robotic technology is the stepless tilt and rotational robotic arm, which is already transforming the parcel processes used for bulk unloading, singulation and induction. A stepless tilt and rotational arm is robotic technology that can tip multiple types of cages or pallets of freight into the production line.

How do robotic tipping arms play out in the CEP hub? Australia Post has successfully integrated this advanced technology into its parcel sortation facilities where it sought to speed up delivery in order to meet online shopping demands. 

 

Speaking of the new facility, former Chief Operating Officer of Australia Post, Bob Black, said:

“We’ve reduced 250,000 human interventions per day. So we’re helping our workforce to be more productive and less likely to suffer stresses and strains with the manual lifting and shifting.”

At its new facility outside of Brisbane, Australia Post has deployed four robotic arms, each able to tip 80 cages of parcels per hour onto the electronic sorting lines. This is almost triple the number achieved with human intervention. The technology feeds the singulation for the automated induction that follows. The emptied roll cages prepared for dispatch will, in turn, be taken to outbound vehicles for loading.

 

2. Robotic pickers

Then there’s the robotic pickers. In parcel sortation, robots are now able to locate items in a pile and recognise their position and size. Using sensors, the robots form their own impression of the shape, measurement and position of each parcel as they pass by on the conveyor as part of a bulk flow. 

In a highly accurate, single pick-to-place movement, robots are able to grasp pickable parcels and transfer them - completely aligned and singulated - into position onto a conveyor for automatic induction into the sortation system.

The robotic solution, now being trialled at a major European parcel logistics operator, takes over traditional manual functions. With increasing ability to match human operatives, it is able to handle even the odd parcels - especially those featuring difficult wrapping, odd shapes or polybags. Their almost human-like movement means they can grab parcels at the right angle on a conveyor. And if they drop items mid-way, robots are able to react intelligently.

To reach this level of intelligence and handling capability, however, robots need to be taught to “think”, using a wide range of parcel profiles and other parcel-resembling items as examples. Ultimately, the machine learning reaches a point where robots can identify machinable parcels. The continuous capture of data contributes to an ever-lasting learning curve.

3. AGVs 

And, then of course, there are the automated guided vehicles (AGV) being integrated into distribution centres. These driver-less, unattended vehicles are being used for tasks typically performed by forklifts, conveyor systems or manual carts. 

The forklift AGV is designed to perform the same functions a human-operated forklift performs, transporting large volumes of parcels throughout the facility in a repetitive manner. Software and sensors guide the movement of these self-propelled vehicles, which are designed for intelligent routing capacities and to avoid collisions.

The implementation of AGVs could potentially eliminate the need for distribution centres to source or train skilled labour for these monotonous and manual tasks, and allow trained operators to focus on other functions. AGVs offer the hub improved worker safety and resource utilisation and are a predictive and reliable solution for repetitive tasks. 

Australia Post, for example, has deployed 23 AGVs in its new facility outside of Brisbane. Its robotic forklifts work seamlessly 24 hours a day to move cages of parcels around the site with no human intervention. They have also started to have a role in the inbound process by handling out-of-gauge items. 

Conclusion

The true extent to which robotic technology will transform internal handling processes in parcel distribution has not yet been fully explored. But certainly, robotics are adding a powerful functionality to the handling processes and already reshaping and redefining automation. Now the technology seems to be gaining momentum and robots will hold an important key for those CEP businesses wishing to find further efficiencies, lower operating costs and additional capacity. For some regions and some large parcel hubs, robots will also alleviate the pain of sourcing staff.
