In Episode 7 of the Exoskeletons and Wearable Robotics Podcast, hosts Bobby Marinov (ExR) and Tom Sugar (WearRA) team up to uncover the recurring challenges that have slowed the widespread adoption of exoskeleton technology—issues like fit, comfort, proving the return on investment (ROI), limitations in range of motion, heat management, and more. The episode delves into these barriers to understand why the path to widespread adoption is more challenging than it may seem.
ExR’s perspective: In the first six Exoskeletons and Wearable Robotics Podcast episodes, we’ve explored the different types of exoskeletons, their applications, and their incredible potential. We stand at the threshold of a physical revolution—just as the digital revolution transformed how we communicate and work, physical augmentation tools like exoskeletons could reshape how we approach manual labor, physical rehabilitation, and even our independence. This synergy between human intuition and robotic endurance promises to bring out the best of both worlds. But if the potential is so immense, why aren’t exoskeletons already part of everyday life or common in workplaces? Why haven’t they received the same massive investments as technologies like VR, drones, or cryptocurrency? The reality is more complex.

Episode 7 Summary:
Episode 7 of the Exoskeletons and Wearable Robotics Podcast dives into the hurdles preventing the mass adoption of exoskeleton technology, despite its recognized potential benefits. The discussion begins with the challenge of getting people to wear exoskeletons, emphasizing the need for comfort, ease of use, and a quick donning and doffing process. Unlike tools used briefly, exoskeletons remain worn even after a task is completed, making comfort crucial. The device must be lightweight and avoid causing overheating, particularly in high-sweat areas like the lower back. Innovations in breathable materials and customizable, lightweight designs are helping address these concerns.
The episode also explores the concept of “static fit” (how an exoskeleton feels when stationary) versus “active fit” (how it performs during movement), and the potential issues of chafing or sliding during use. The conversation highlights that human joints, like the knee, are complex and not just simple hinge points. Misalignment during movement can lead to discomfort, so exoskeleton designs must accommodate these biomechanical realities.
Another major topic is the cognitive cost of using exoskeletons. Some systems require users to adapt over time, like learning to ride a bike, before feeling natural. The need for intuitive operation is emphasized, focusing on reducing training time to ensure devices are practical for workplaces. Additionally, there is a significant challenge in implementing exoskeletons in industrial settings, which includes training, maintenance, and proper use protocols. The podcast notes that standards organizations are working on guidelines for safe and effective exoskeleton use.
The conversation discusses the importance of selecting a suitable exoskeleton for specific tasks. Misapplication can lead to inefficacy and wasted investment. Moreover, the return on investment is crucial, especially in regions like the United States, where businesses prioritize cost-effectiveness. While some places like Japan and Western Europe offer government subsidies for exoskeletons, the U.S. largely relies on individual companies to justify these investments.
A recurring theme is the need for exoskeleton technology to be immediately beneficial and intuitive, akin to how cell phones found their initial market with business users before widespread adoption. The hosts stress the importance of popularizing successful applications of exoskeletons, such as in logistics and agriculture, to build broader awareness and acceptance.
The episode ends with a call to action for the community to collaborate and share knowledge to accelerate adoption and development. The hosts express optimism about the future, mentioning upcoming episodes focused on organizations working to integrate exoskeletons into everyday use.
