How Cobots Examine to People

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

Generally, the reply is just not as clear-cut as you’d first assume.

Once you consider manufacturing robots, you most likely 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 will probably appear apparent that such fast-moving robots would improve the productiveness of these duties.

However, robotic productiveness is just not at all times so clear-cut. The velocity of the robotic would not essentially translate right into a extra productive course of total.

Collaborative robots (or cobots) are an ideal instance of this. Cobots normally transfer extra slowly than typical industrial robots and may even transfer extra slowly than human staff.

Does their gradual velocity 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 had been to fixate on this measure of productiveness, you’d possible prioritize the velocity of the robotic. However, simply because a robotic cell works sooner doesn’t suggest that your complete course of will essentially be extra productive.

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

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

Human vs robotic productiveness: a posh query

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

They examine the velocity of the robotic with the velocity of their human staff or with different kinds 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 job: stacking packing containers onto considered one of two wood pallets.

How a robotic performs the duty

Image a robotic performing the palletizing job.

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

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

The robotic operates continuously with out breaks.

How a human performs the duty

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

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

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

Generally, lots of packing containers pile up on the conveyor when the employee hasn’t received 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 at all times speeding to attempt to meet up with the duty even after they attempt to do the duty rapidly.

Which of those two methods appears extra productive to you?

When do robots improve productiveness in a facility?

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

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

Within the instance, palletizing is just not a really appropriate job for human staff. To palletize packing containers effectively, it’s worthwhile to work constantly at a constant price and accuracy. Robots are at all times constant however people should not.

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

Once you apply a robotic to a bottleneck job that’s already not job for a human, that is typically the place productiveness enhancements are most clear.

Hear from firms which have used robotic productiveness the appropriate method

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

We’ve got an entire assortment of case research of assorted firms which have used robotics to spice up productiveness of their facility.

An awesome 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.
