[MUSIC PLAYING] One way I've described running with the exoskeletons is you imagine someone was running behind you and holding little ropes that were attached to your heels. And every time you pushed off the ground, instead of having you do all the work, someone else lifted your foot for you. Feels very springy and very bouncy compared to normal ru... Read More

Questions & Answers

Q: How can exoskeletons make running easier?

Exoskeletons reduce the energy cost of running by assisting with the pushing off the ground and the work of the calf muscles. This makes the running movement feel lighter and springier.

Q: Who can benefit from using exoskeletons for running?

Any individual who needs to run for work or those who want to improve their running ability can benefit from exoskeletons. It can also help individuals keep up with faster runners, such as during recreational activities.

Q: How much improvement in energy cost can be achieved with exoskeletons?

Research has shown that using exoskeletons for running can lead to a 15% improvement in energy cost compared to running in normal shoes. This reduction in effort makes running feel easier and more efficient.

Q: Can exoskeletons be used for commuting?

Yes, exoskeletons can potentially be used for the first/last mile problem in commuting. By attaching the exoskeleton to shoes, individuals can cover short distances without breaking a sweat, making it a convenient and time-saving tool.

Summary & Key Takeaways

• Only 20% of Americans have gone for a jog in the last year, often due to not feeling athletic or skilled at running.

• Exoskeletons can make running easier by reducing the energy cost associated with pushing off the ground and the work of the calf muscles.

• An exoskeleton for running consists of a carbon fiber frame attached to the ankle, with a lever connected to the shoe that extends the ankle and reduces the effort required.
