How Cobots Evaluate to People

Productiveness is an usually debated query in robotics. Is robotic productiveness actually higher than the productiveness of human employees?

Typically, the reply just isn’t as clear-cut as you’d first assume.

Whenever you consider manufacturing robots, you in all probability visualize one thing just like the super-fast delta robots doing choose and place on manufacturing unit conveyors. Or maybe you visualize the quick, highly-accurate welding robots in automobile factories.

In these examples, it could actually appear apparent that such fast-moving robots would enhance the productiveness of these duties.

However, robotic productiveness just isn’t all the time so clear-cut. The pace of the robotic would not essentially translate right into a extra productive course of general.

Collaborative robots (or cobots) are an ideal instance of this. Cobots often transfer extra slowly than standard industrial robots and might even transfer extra slowly than human employees.

Does their sluggish pace imply that cobots are extra productive? Not essentially…

The definition of robotic productiveness

Robotic productiveness means the ratio of enter to output in manufacturing {that a} robotic cell can obtain. Like manufacturing productiveness it’s a measure of effectivity. The extra a robotic cell produces in a selected time interval, the extra productive it’s.

Nevertheless, the productiveness of a person robotic cell is just one side of productiveness. In case you have been to fixate on this measure of productiveness, you’d doubtless prioritize the pace of the robotic. However, simply because a robotic cell works sooner does not imply that your whole course of will essentially be extra productive.

You additionally must keep in mind how robots have an effect on the general productiveness of your course of.

Robots could be a key device for rising the productiveness of your manufacturing operations. However, they’ll solely do that in the event you place the robotic at a bottleneck activity. We now have seen many examples of conditions the place robots have been used to ease stress on a bottleneck activity. This has led to a rise in productiveness in your complete operation.

Human vs robotic productiveness: a posh query

When individuals see collaborative robots in motion for the primary time, they often say “These robots transfer very slowly.”

They examine the pace of the robotic with the pace of their human employees or with different sorts of automation. They discover it laborious to image how a slower-moving robotic might assist enhance their productiveness.

Let’s take an instance of a selected activity: stacking containers onto one in all two picket pallets.

How a robotic performs the duty

Image a robotic performing the palletizing activity.

A conveyor feeds the robotic cell with containers. The containers arrive at irregular intervals as they’re packaged by human employees beforehand within the line.

The robotic waits patiently for a field to reach. Every time a field arrives, the robotic reads its label. If the label is purple, the robotic instantly locations it on the left pallet. If the label is inexperienced, the robotic locations it on the best pallet.

The robotic operates consistently with out breaks.

How a human performs the duty

On this case, a human employee is tasked with palletizing the containers. Because the containers don’t arrive in a short time, this employee additionally has an unrelated inspection activity that they carry out on the similar time.

The containers queue up on the finish of the conveyor. When sufficient of the containers have queued up, the employee rushes over from their inspection activity and begins palletizing the containers.

They must examine the label of every field manually. They put the field on the right pallet relying on the colour of its label. As a result of the employee is transferring rapidly, they don’t place the containers as precisely on the pallet because the robotic would.

Typically, quite a lot of containers pile up on the conveyor when the employee hasn’t acquired time to do the palletizing or is on a break.

The result’s that palletizing could be very inconsistent. The standard of the palletizing suffers and the employee is all the time dashing to attempt to meet up with the duty even once they attempt to do the duty rapidly.

Which of those two methods appears extra productive to you?

When do robots enhance productiveness in a facility?

As you may see within the instance above, the pace of operation is not the one side of productiveness. Consistency additionally has a big impact on how productive the duty might be.

Robots enhance productiveness when they’re used for duties that people battle with within the first place.

Within the instance, palletizing just isn’t a really appropriate activity for human employees. To palletize containers effectively, it’s essential work constantly at a constant charge and accuracy. Robots are all the time constant however people should not.

Staff usually see this potential themselves. One examine discovered that 77% of individuals would welcome robotic help at work if it meant that the variety of handbook processes decreased. As people, we excel at cognitive duties however extremely repetitive handbook duties are simply not the perfect use of our expertise.

Whenever you apply a robotic to a bottleneck activity that’s already not an excellent activity for a human, that is usually the place productiveness enhancements are most clear.

Hear from corporations which have used robotic productiveness the best approach

You needn’t take our phrase for it that robots can enhance your productiveness.

We now have an entire assortment of case research of assorted corporations which have used robotics to spice up productiveness of their facility.

A fantastic instance of this in motion is the case examine of how French producer Alliora elevated its productiveness with robotic palletizing. You’ll be able to examine their experiences right here.
