Researchers at Technical University of Munich have developed WalkON, innovative robotic shorts that significantly reduce walking effort, potentially transforming mobility assistance for elderly and physically limited individuals, much like this robotic knee exoskeleton.
The Innovation: Interestingengineering reports that the shorts function similarly to e-bikes, using artificial tendons and smart motors to assist hip movement during walking. Unlike traditional exoskeletons, WalkON appears as normal clothing while providing substantial energy savings:
- 18% less energy for uphill walking
- 10% reduction on level ground
- Equivalent to losing 6-10 kg of body weight
Technical Details: Sciencedaily reports that the system features two thin tendons extending from thigh to waist, automatically adapting to walking speed with no pre-settings required. A measuring device monitors hip angle and velocity, triggering motor assistance at precise moments during walking motion.
User Impact: Early testing shows strong user acceptance, with participants rating control confidence over 6 out of 7 points. The technology particularly benefits elderly individuals not yet needing walkers and people with heart or lung conditions.
Researchers: "These findings emphasize the potential of wearable assistive devices to improve efficiency in outdoor walking, suggesting promising implications for promoting physical well-being and advancing mobility, particularly during the later stages of life."
Looking ahead: Researchers envision a modular future where users can easily assemble their own robotic shorts for activities like mountain hiking. This development represents a significant step toward making assistive technology more accessible and user-friendly for everyone who needs it.
