How many robots does it take to run a grocery store?

This is a grocery packing warehouse in the south-east of London. 00:00:00
Folks have ordered their groceries online, 00:00:03
and instead of people walking up and down the aisles 00:00:04
of a traditional grocery store to pick up items, 00:00:06
these little devices move more than a million items every day between them. 00:00:09
Instead of trying to build machines that fit into a world designed for humans, 00:00:13
this entire facility, the size of seven football fields, 00:00:16
is custom-built to make this as efficient as possible. 00:00:20
I cannot get across on camera just how incredibly large this whole place is. 00:00:22
The top speed of those boxes is about 14 kilometres an hour and they pass within five millimetres 00:00:29
of each other when they move. 00:00:34
So how many robots are there in the hive? 00:00:35
Well that depends on how you count them. 00:00:39
What you're looking at behind me is the hive. 00:00:42
We've got the grid which is the metal structure. 00:00:45
It's filled with products so that product is housed within what we call totes or these 00:00:48
open boxes that you can see at the top of the grid. 00:00:53
We have around 2,300 bots and they move the stock around the warehouse so that we can 00:00:56
pair it up with customer orders to be delivered. 00:01:01
The bots will move in the X and Y direction, they can also move in the Z direction. 00:01:04
So we have a cable hoist system that means that they can lower down a gripper assembly 00:01:08
and grab onto the stock that we have in the grid. 00:01:13
In some areas we have as deep as 21 totes all in a line. 00:01:16
We have sensors underneath the bot that mean that every time it passes over one of the 00:01:21
squares on the grid, it has a laser underneath it that can tell when it moves over that cell. 00:01:26
So it will say, I've passed a cell, I've passed a cell, I've passed a cell. 00:01:31
We have around 58,000 different types of individual products within the grid. 00:01:34
We'll use the huge amounts of data that we gather to understand what customers are most 00:01:39
likely to order and place them in the easiest to reach locations for bots. 00:01:43
All of that combined means that we can have stock into the warehouse and out again from 00:01:48
our suppliers into a delivery van in just five hours. 00:01:52
The robots deliver their crates over to the packing area. 00:01:56
Some of that packing is done by humans, but there are mechanical arms as well. 00:01:58
One of the big problems they've got to solve is that grocery packaging is designed for 00:02:02
people and the interactions between all the objects they deal with can be complicated. 00:02:06
Currently we're standing underneath the grid structure that we saw earlier. 00:02:11
The robots that we saw are actually dropping off products to the station. 00:02:14
Once they're dropped off, they become in control of the robot, 00:02:18
and the robot decides how to pick them before the grid robot picks up the tote and takes it away again. 00:02:20
There's two 3D cameras above the totes, so it takes an image of the storage box before it picks from it, 00:02:25
decides on the best grasp point, confirms that the product is correct, 00:02:31
and then places it into the customer shopping, and it's doing all of that on live customer orders. 00:02:34
We make sure that we don't mix something that was heavy with something that's soft. 00:02:38
There are things that a robot can't pack, things such as very, very heavy, very large or very fragile items, 00:02:42
but there's a lot of range in between that. 00:02:47
It's fairly safe to call each individual packing arm a robot. 00:02:49
Each one has a separate controller and it has to make a lot of decisions in real time 00:02:52
using cameras and sensors on each individual arm. 00:02:55
But here in the Hive, it's not quite as simple. 00:02:58
Controlling all of this is what we refer to as the Hive Mind, 00:03:02
so this artificial intelligence system that controls everything. 00:03:05
Once the stop comes in, from that exact point that it enters the system, the hive mind will track its every single movement. 00:03:09
The hive mind will tell the bots exactly where they need to stop, but it is the bot's control system that allows it to follow a movement profile and stop exactly as the hive mind expects it to. 00:03:16
There's just a 5mm gap between bots, so that's both as they pass each other and if they stop next to a bot as well. 00:03:28
This bot with the orange light may have experienced something within its sensors and all of those readings it's taking 00:03:35
that when it feeds that back to the hive mind it's not quite what the hive mind was expecting 00:03:41
so it just brings it to a safe stop for investigation. 00:03:47
We do have a number of grid operators that sit at the edge of the grid 00:03:50
and they're able to use our CCTV system that we have above the grid 00:03:55
to look at exactly what's going on with that bot 00:03:59
and they can try and fix that remotely and send commands to the bot wirelessly. 00:04:02
The boundary between individual and group is a little blurry. 00:04:06
Is a termite colony and a collection of individuals working together or one big superorganism? 00:04:09
Is the microbiome in your gut part of you? 00:04:14
Because in the last couple of decades, scientists have started to work out 00:04:16
whether bacteria in your digestive system produce and consume neurotransmitters 00:04:19
that affect how you think. 00:04:23
But most people wouldn't consider their gut bacteria to be part of them. 00:04:25
We tend to ascribe intelligence and identity to things that act at roughly our scale. 00:04:28
It's easy to look at the hive, see the moving boxes, and go, 00:04:33
OK, 2,000 robots. 00:04:35
But with only one controller, and the boxes just following the paths they're given, 00:04:37
I'd say there's a good argument that that is one robot 00:04:41
with 2,000 ways to interact with the world. 00:04:44
Thank you so much to everyone here at Ocado. 00:04:47
There is a link to them and more about their technology in the description. 00:04:50
