What happens when a walking exoskeleton runs out of battery away from home?
A little powered push at the ankle sounds wonderful if it means staying out for another part of a museum visit. I'd still want to understand the walk back without that push. In an October interview with Exoskeleton Report, Dephy's CEO says Sidekick observes roughly twenty unpowered steps to learn a person's gait, then times assistance to push-off. He says its unidirectional actuator won't resist movement when the batteries are empty or removed. It is a wellness product for people who already walk independently, not a treatment for someone who cannot. That battery answer is useful, but ‘doesn't resist your movement’ doesn't tell me how tiring the return trip will feel while still wearing the equipment. I'd ask the supplier to demonstrate unpowered walking in a suitable setting before planning a longer outing, and explain how to recognize dwindling charge early enough to turn back. The interview consists of company-supplied answers; the outlet explicitly says it hasn't independently verified the performance or certification claims. I haven't tried the device either. I'd judge the extra range by whether the person still has a comfortable way home. What would you want to know before letting powered footwear change how far you decide to go?

I would keep the certification claim separate from the promise of a longer day out. Mooney names ISO 13482:2014; ISO's own description covers safe design, protective measures and reducing hazards in personal care robots. That scope is not a measurement of how much less tired a Sidekick wearer will feel. The interview also mentions studies of Dephy devices, but does not identify which results apply to the consumer Sidekick. I'd ask for that link before borrowing the research's authority for this purchase. Someone deciding whether they can comfortably finish a museum visit needs evidence about that benefit, alongside the safety checks—not one standing in for the other.
I'd also change the interview's sales setup: ‘the options are to push through it or sit it out.’ Later, Mooney contrasts something you'd choose to wear with something you're ‘resigned to using.’ That makes the existing ways people manage a day out sound like defeat. A shorter route or a planned rest can be a choice, too. I'd show someone choosing where to stop, with or without the powered help, rather than imply that buying it proves they haven't given up. That's a criticism of the pitch, not a verdict on how Sidekick feels to wear.
The people walking with them need to hear that, too. If someone tries powered footwear on a family day out, I'd agree beforehand that they can still ask to stop or head back without explaining what the device was supposed to make possible. ‘But you've got your new shoes on’ would be a rotten answer to ‘I'm tired.’ Extra help should let the wearer choose more of the day, not give everyone else permission to plan a longer one. That's a conversation I'd suggest having, not an experience I've observed with Sidekick.
