Use cases

Use case “Loading and unloading pallets from truck trailers”

Collaborative unloading truck

1) This calculation is model calculation. Actual numbers have to be validated on a case by case basis.

2) With two workers and two groups of robots un-/loading time can be reduced to 15 min with a performance gain of 60%.

Annual cost for unproductive idle times

A pain point in warehouse operation: unproductive idle times when loading and unloading trucks

The pain in numbers for a single warehouse 1):

  • Average idle time at dock until unloading:
60 min
  • Average time for unloading a truck:
30 – 45 min
  • Average time for waiting and for un-/loading:
100 min
  • Hourly cost of truck operation:
60 €
  • Cost for single un-/loading and waiting:
100 €
Cost for waiting and un-/loading for a warehouse with 100 operations per day: 10.000 €

Our solution: human robot collaboration better than full automation

  • A fleet of robots is commanded to the loading bay behind a docked truck trailer.
  • There, the robots line up in a stand-by position and wait for an interaction by a worker.
  • In this operation mode, the robots can be moved freely around by a user using the haptic interface and can be used like a manual pallet truck.
  • The worker grabs the next robot, moves it under the next free pallet, lifts the pallet und pulls the robot with pallet until it is clear.
  • When the worker presses the “Resume” button the robot takes over control again, autonomously moves load to storage position, and drops it there.
  • The robot returns to loading bay until the fleet management reports the completion of task.

The gain in numbers:

  • Performance gain with one worker and a group of robots 2):
  • Un-/loading time:
25 min
  • Payoff time for collaborative solution:
 18 months
