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.

What’s a dynamometer? And why does it matter for Puck® and the WAM® Arm?

A dynamometer measures speed, torque, and power under load.
You drive a motor or joint, and it tells you exactly what the hardware is producing.

For us, that’s critical. At Barrett, equipment like this helps push our technology to the limit. Testing, straining, and qualiifying that our calculations match reality.

We use it to:
- Measure motor torque
- Validate small scale tests
- Evaluate changing loads over time
- See how firmware changes translate into physical behavior

Having it in-house means we can tie calculations into the real world.

And it ensures every Puck® you buy runs at exactly the right specs.

Have you spent the last 3 years trying to build the ~perfect~ motor controller?

And still nothing works?

Believe it or not, we've spent 30 years perfecting it, and we're not stopping any time soon.

Difference is, our motor controller:
1) works first try
2) fits on your fingertip
3) is on your desk in 3 clicks, not 3 decades

Don't believe us?

Visit barrett.com/puck, and you'll have some in your pocket in 3 clicks at the most.

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.

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 :)
