Using a vacuum to pick up baggage is a very interesting choice. I wonder how it would fare with extremely uneven surfaces or even porous ones.
Also --- I couldn't see any obvious sensors. What sensors are you using to perceive the bag? I am imagining some kind of RGB-D sensor like a Kinect (or its successors like the Orbbec).
Suction has gotten us pretty far at the prototype level but definitely isn't enough - we're testing out some new gripper designs that use suction as a broader part of an overall grasping system.
For these videos we have lidars and two Intel Realsense depth cameras mounted to the safety cage and on a wall. We're working on moving as many sensor on-robot as possible in the near future to aid with deployability.
