[Dprglist] Grocery robots

[Doug Paradis]

I really liked how they handled which wheels had control of the robot. I am
still a little confused on how it works.
It appears that:
1) The crates in the grids (white bins) are where the products are stored.
2) The white bins can be removed and replaced with filled white bins by the
robots.
3) Robots can collect products (grippers to reach into the white bins not
shown).
4) Collected products are placed into a green bin also located in the grid
(see 1:09).
5) Green bins can be retrieved by the robots and taken to a checkout
station.
5) Green bins are loaded onto conveyor belt where they go to a scanning
station.
6) Products are picked up by a vacuum gripper, bar-code scanned, then put
into a red bin.
7) I assume if the gripper fails, a person steps in and scans the item,
based on the overlaying text.
8) There are most likely different types of robots for (blue - see 2:35)
stocking vs. (black) gathering an order vs. (green ?) returning a green bin.
9) Robots can drive to charging station as required.
10) Robots are loaded with stocking bins (white) by humans (see 0.29). I
think this is a shot of the stocking area (note: blue robots).

One confusing shot shows a red bin in the grid (see 0:41). I would think
that all red bins would be checked out orders.

It would really be interesting to see the gripper that they use to load the
order. It must be pretty flexible to handle all of the various types of
products. I wonder if they use a load cell to verify if the robot picked up
the correct amount of an item or in fact the correct item.
Ezra, thanks for sharing.

Doug P.
