That’s an interesting topic. But what specifically constitutes the biggest obstacle to the power supply issue? Isn’t simply increasing battery capacity the solution?

Yes, that’s true, if you think about it simply. However, increasing capacity makes the battery heavier and larger, which can be a burden to the wearer. This can actually hinder the robot’s primary function of “assisting movement.” Therefore, the key is to create a battery that’s lightweight, thin, and highly efficient.

Oh, there’s the weight issue. So how can flexible battery technology and external power be applied? Are there any commercialized examples?

While not many have been fully commercialized yet, research is actively underway. For example, there’s technology that generates electricity with movement, like artificial muscles. Wireless charging methods that can be used while charging outside are also being considered. Ultimately, all of this is directly related to user convenience, so we’re approaching it from various perspectives.

I see. Ultimately, technological advancements that improve usability are crucial. Thank you for the helpful information!
