🌅Exos 101

4mo ago

I share research & insights on biomechanics, exoskeletons & wearable tech. Vanderbilt University Professor. HeroWear Co-Founder & Chief Scientist.

🚨 The top 10 reasons industrial exoskeletons fail in the real world:

1. They’re uncomfortable — physically, thermally, or psychosocially

2. They interfere with movement or are hard to use

3. They’re too cumbersome to deploy at scale

4. They don’t actually fit the full workforce

5. Workers don’t perceive enough benefit

6. Poor (or nonexistent) implementation

7. Expectations don’t match reality

8. Lack of management support

9. They’re not worth it (no ROI)

10. Poor safety culture

👷🏽‍♂️ The first five are primarily user experience problems.


You can’t fake these with marketing copy, first-impression demos, trendy buzzwords, or cherry-picked testimonials. If a device doesn’t fit women—or people of different shapes and sizes—it becomes obvious almost immediately.

The real test? Deploy exos properly (fit, training, support), then check back with workers in a couple months. If the exos have been abandoned, you have your answer. If workers love them, you’ll know.

🏭 The next five are primarily organizational problems.


If you’re serious about long-term impact on worker health, well-being, and operational efficiency, you have to get these right too. Otherwise, exos—or any new equipment—end up as the next fad collecting dust in a storage room.

😎 But here’s the cool thing…

If you take the inverse of each of those 10 statements, that’s where the real magic happens.


And it is happening—around the world—for companies using exos that are truly well-matched to their use case.

👏🏽 I’ve spent over a decade researching occupational biomechanics and developing exoskeletons to reduce #MSDs. It’s been incredible to watch the field evolve—from early failures, to pilot-phase purgatory, to today’s growing list of companies seeing sustained, multi-year adoption across their operations, including:

• Fewer work-related injuries
• Higher productivity
• Lower turnover
• Positive ROI

👉🏽 Thinking about deploying exos—or had a pilot stall? What actually broke: the tech, the rollout, the culture, the business case, or the assumptions? Comment below.
