Barrett Technology, LLC

Barrett Technology, LLC Barrett Technology is the leader in advanced robotic manipulators and medical robotics.

As a fresh spin-off from the Artificial Intelligence Laboratory at the Massachusetts Institute of Technology in 1990, Barrett tasked itself with the stewardship of the first haptic robot arm, named the WAM™ arm. This manipulator embodies Transparent Dynamics™ drives that fundamentally break from the conventional design of robotic manipulators. With a market yet to exist for haptic devices, Barrett diligently honed the technology during the 1990s with grants from DoE, NASA, and NSF, as well as sales to key advanced-robotics laboratories all over the world. Since 1990, Barrett Technology has pioneered core technology underlying new levels of flexibility in articulated arms and hands. Today, Barrett is the leader in advanced robotic manipulators,
earning a place in the Guinness Book of World Records for its advanced manipulator technology. Barrett provides an unmatched degree of versatility to support the broadest array of applications.

In 2016, we still had the Penny...

In 2026, you've got the Puck® (and it's not going anywhere).

You'd be shocked how much power is packed in such a small space.

It's hard to match versatility with this much power, but the Puck handles almost any motor you can fit on a desk, with a peak power up to 400W.

We're not getting rid of the Puck any time soon.

Sometimes we give a little ~too much~ away.

It's rare we hand things out FOR FREE, but right now our website has the design files for the original WAM® arm.

From design files to the full CAD construction, we're hoping that budding engineers to experienced designers can learn from the WAM®. Dimensions, joints, and everything.

What was the World's Most Advanced Robot Arm is now three clicks away.

Go ahead and dig in...

Because DOING is the only way to mastery.

The world is loud enough...

Signal to noise ratio is all the rage in startups, YC, and the founder world these days.

And we promise you this: the Puck® is all signal, without the noise.

With Puck®, you've found focus, accuracy, intensity, power, precision, all in one.

With Puck®, you've found quiet... at last!

When it comes to Puck® Testimonials, we're always looking for more examples of amazing work.

But one example we're especially proud of is our own: Burt®

Burt® is a rehab robot, the flagship product of Barrett Technology's other half, Barrett Medical. Inside of Burt®, there are three Puck® P4-37s controlling three homemade Burt® Motors, which together create haptic feedback, graded assistance, and safe backdrivability.

Building what we need helps us understand exactly how to improve, iterate, and innovate on the existing Puck® models.

Our goal is to provide excellent service with amazing engineering, and your feedback helps us build just that. If you're building with any level of Puck® (P3s and P4s alike) we'd love to hear what you've crafted.

Introducing the Puck® Utility Suite -- our way of making prototyping easy and accessible for your creations.

With Puck®, our goal has always been to allow your team to test, scale, and produce as quickly as possible. Puck Utility Suite is the next evolution of that mission.

As a software suite of three tools: Utility, Tuner, and Fader, we're eliminating the up front learning curve of working with Puck®.

To make it even clearer: If you buy a Dev Kit today, you'll be spinning motors by the end of the week using Puck® Utility Suite.

We've made these tools free of charge and accessible on our website and git repositories if you're interested in iterating towards your unique needs.

Check it out here: https://barrett.com/puck-software

Something new is on its way to your workbench.

While we can't say what it is just yet -- we know you'll want to be the first to know...

We can tell you that its:
- Small
- Powerful
- Game-changing tech

(Though if you're a Puck® user, that's nothing foreign to you!)

Want to make sure you don't miss out?

DM us with your email, or comment on this post and we'll make sure to send you details right when its released.

Two things we learned at last week's Humanoid Summit!

1. Human robot interaction is here to stay:

Robots working directly with humans are only getting closer to the norm rather than a distant future. Whether its training robotic systems with human behavior, or using robots to do the dishes, robots are improving lives.

2. Humanoid robotics requires space-efficient solutions:

And when that comes to interacting with humans, that means shielding complex drive systems (motors, cables, drivers, batteries) internally. With size reduction comes complexities, but we've got that covered :)

If you're building a motor controller from scratch here's how:

//////// just kidding ////////

You don't want to do that -- if you've tried, you're probably overwhelmed.

Puck P4 is smaller, stronger, and smarter...
...AND you don't have to build it from scratch.

Save yourself a year of work and visit barrett.com/puck today. Starting at $499.

Today is Barrett's last day at the Humanoid Robotics Conference, and the floor is full of crazy engineering and wild ideas.

Lots of not-quite-humans and dancing robots running around the space. I think we've said “how did they even build that?” probably 100 times before noon.

And check this one out!👇
Doctor Octopus meets the Puck®.

Always fun seeing how different teams think about actuation, scale, and control — especially when worlds collide like this.

If you’re here too, come say hi.

Hexagons are the bestagons.

Engineers obsess over efficiency, and hexagons are nature's most efficient shape. They tessellate perfectly, maximizing area with minimal perimeter, and they show up everywhere from honeycombs to snowflakes.

So when we were designing stickers for our Puck® motor controllers, the choice was obvious.

And if you zoom in, you'll spot the Easter egg: every serial number is written in hexadecimal. Because when you're already geeking out over geometry, why not go full base-16?

Hex is the most compact way to represent binary data. Efficient, elegant, and speaks directly to how computers think. Just like our Pucks: penny-sized, yet powerful enough to drive the most advanced robots in the world.

Form follows function. Always.
