The Challenge

The competition consists on unfolding and folding rectangular clothes from the Household Cloth Object Set. Participants will receive this set for free, being able to keep it afterwards. Our intention is to identify and gather the community, so we look for an easy entry point where participants are able to participate if they are interested in perception, manipulation, or both.

The competition is part of the 6th Robotic Grasping and Manipulation Competition of IROS 2022.

Details of the setups, tasks and scoring can be found on the Rulebook.

Perception

Task 1.1. Grasp point detection

This task consists on selecting a suitable grasping point on a cloth that can be either crumpled, folded or flat on a table. The selected point must correspond to a graspable corner of the cloth, providing the necessary information, such as coordinates and approach direction vector.

Manipulation

Task 2.1. Unfolding

This task consists on grasping the cloth and manipulating it until it is placed flat on the table. The cloth initial configuration can be either crumpled or folded and the final configuration of the task is flat. This task can be performed in many different ways, having no limitations on the strategies used. That is to say, it can be performed for example with a bimanual robotic system by grasping directly the corners, performing edge tracing to the second corner or by pushing and sliding the cloth on the table until it is flat. However, the evaluation will take into account several parameters as the total execution time or the number of state transitions performed since the task starts.

Task 2.2. Folding

The last task of the track consists on folding the cloth times once is flat on the table. In order to correctly perform this task, the object must be folded following the folding protocol.

The Household Cloth Object Set

The object set consists on a collection of common household cloth objects that can be found in any house, including towels, bedsheets, tablecloths and napkins. The following images presents an overview of the objects from the set. The table picks up the physical properties of the objects as their dimension, weight and % of elasticity under tension.
