Collaborative robotics: Building robots that can safely work with humans

Have you ever seen a manufacturing robot in action? Watching these things whisk around something like a two-ton car makes it clear, at a visceral level, why there are fences around these robots. You definitely don’t want to get into the way.

By contrast, collaborative robotics is an emerging technology that enables robots to work together in close proximity with humans. This type of robotics has the potential to transform manufacturing, logistics, agriculture, medicine, and other fields.

A quick note on terminology, collaborative robots are also called?cobots.

In order to explore some recent developments in cobots, I used the following?Mergeflow data overview snapshot?(click on the image to see the snapshot):

I started by looking at some companies from this snapshot (actually, I also went a bit further than the snapshot and looked at companies and R&D in some more detail–you can do this too, if you like, by signing up for a?14-day free trial of Mergeflow).

Rapid Robotics: Machine operating cobots for rent

Rapid Robotics?makes cobots that perform machine operator tasks. And they are called “Rapid Robotics” because their cobots can be deployed very quickly, within hours. This is orders of magnitudes faster than having to program a more traditional robot.

Rapid Robotics don’t sell their robots. You can rent them, for $2,100 / month. They build cobots to “help manufacturers solve labor shortages”, according to their website. And they have an interactive cost calculator that directly compares the costs of their cobots to the costs of a human machine operator:

In 2021, Rapid Robotics raised $36.7M Series B from?Kleiner Perkins,?Tiger Global,?NEA,?Greycroft,?Bee Partners, and?468 Capital.

MOV.AI: The ‘word processor of robotics’?

(I’ll explain below why I think MOV.AI might be the ‘word processor of robotics’)

Lisbon-based MOV.AI makes software that makes it easier to build and operate robotic solutions (not just cobots but other kinds of robots as well). Here’s the problem they solve: When you think about it, a robot is a system that requires computing units, sensors, and actuators to work together to perform some task. And there is an open source software called?ROS?(Robot Operating System), which is widely used across industries and applications. But when you want to actually build, deploy, and operate robots, ROS only gets you so far. For example, if you exchange one sensor for another, you’ll probably have to re-write a lot of ROS code for the new sensor. With MOV.AI’s?Robotics Engine Platform, you don’t have to do this anymore. This is because MOV.AI adds levels of abstraction to ROS, so you’ll have to worry less about lower-level implementation details.

This is why I think it might be called ‘word processor of robotics’: If you are old enough to remember writing papers etc. with?LaTeX, you know how much work it can be just to make a paragraph of text appear in a certain font, size, color, width, etc.. But now with word processors like Google Docs or Word, you simply mark the text, set a few parameters in a GUI, and you’re done. I think MOV.AI is a bit like this, for robotics.

In 2020, MOV.AI raised $4M from?SOMV,?NFX, and?Viola Ventures.

Micropsi Industries: Hand-eye coordination for cobots

Training a cobot without writing code? Just by showing it what it’s supposed to do, and giving it a bit of guidance? Berlin-based?Micropsi Industries?helps you do this. They make an AI-powered robot controller called MIRAI (which I assume stands for Micropsi Industries Robot AI). They have a video on their website that shows you what MIRAI can do:

According to?their website, MIRAI currently works with robots from ABB and Universal Robots. And if you’d like to dig deeper, you can get a?description of what’s included with MIRAI, and how you can set it up?from Micropsi’s website.

In February 2022, Micropsi Industries raised $30M Series B from?Metaplanet,?VSquared,?Ahren Innovation Capital,?Project A Ventures, and Merck’s?M Ventures.

Multiply Labs: Cobots for making individualized drugs

Basically by definition, individualized drugs are something that you don’t make in high volumes. It’s not “many instances of one type” but “few instances of many types”. This sounds like a typical “cobot problem”: Rather than building and deploying a robotics solution once and then let it run, you need robots that can be retrained all the time.

Multiply Labs?makes such robotic manufacturing systems for individualized drugs. And these systems include cobots. According to?their website, co-founder?Alice Melocchi?had the idea for Multiply Labs when she did a lab tour of her friend and later co-founder?Fred Parietti: Alice was making drugs by hand, and Fred was working on robotic limbs.

In 2021, Multiply Labs raised $20M Series A from?Casdin Capital,?Lux Capital,?Founders Fund,?Fifty Years, and?Garage Capital.

How to teach human interaction to a cobot

So, how can you teach a robot how to interact with a human? How does human movement, motor control and planning work? How can a robot infer what its human collaborator might be up to next? What’s the R&D behind this?
