With so few products picked overall, it is perhaps too early
to draw meaningful conclusions. But we will offer up some observations. First, the product most commonly picked was the glue bottle, which was successfully picked seven times. This is in part due to the fact that it was alone in the bin in four
out of five layouts, and paired with only one other product in the fifth. In addition, the bottle was standing upright and was placed inside the bin relatively far from the walls, allowing easy access by grippers. Thus, it had the most favorable
arrangements, provided good affordances for picking, and saw the most success. The package of Oreos and the spark plugs were also targeted in every layout. The cookies were successfully picked only three times (and dropped once) and
the spark plug only once (and mis-picked once). The spark plug was in a box, but was still rather small. Surprisingly, the two soft-cover books were picked relatively often (three times each). Several of these picks involved attaching the suction
to one cover of the book, which left the pages dangling.
A potential complaint is that moving such items using this
approach could potentially damage them.
