Hypershell

All three models in the Hypershell range share the same major update, HyperIntuition. This replaces the previous rule-based software (you walk, it adds power) with a system that continuously processes motion and adjusts torque in real time. The argument is that real-world motion is irregular, and that the exoskeleton needs to adapt to the ever-changing range of motion. We naturally stop and start, slow down, speed up, step, move, climb, and adapt to uneven ground, but traditional exoskeleton systems were rubbish about this. They only really succeeded by recognizing repetitive walking patterns and, as a result, made me feel more like a robot than a human being assisted by a robot.

Hypershell claims a response time of 0.31 seconds and a “human-machine synchronization rate of 97.5 percent” across diverse terrain, whatever that means. Hypershell told me the goal wasn’t just to add force, but to deliver it at the right moment, so the support feels consistent with your movement rather than forced upon it. In theory, this means that assistance reacts smoothly, increasing the harder you work, and decreasing once you stop. It’s a bold claim, and I’ve been testing it for the past two weeks.

Setting up the Hypershell X Ultra S remains extremely simple, with excellent step-by-step installation instructions via the app. I was testing an earlier version of the iOS app but was told the final version would be essentially identical. Getting the fit right is very important, and something I learned from previous models. Making sure the actuators are properly aligned and not too tight on the hips is key.

Compared to previous Hypershell generations, the X Ultra S has superior padding around the hips which I immediately appreciated. The straps are easy to adjust, and once installed, the system feels balanced. Please don’t think for a moment that the 5.5 lb weight will magically melt off when you start using it. No matter how many times I walked in those shoes, I never forgot they were there.

It suffers from some of the same issues I’ve had with all exoskeletons, particularly the fact that your front pants pockets become completely useless, and backpacks tend to sit on top of the battery, but not in a good way. This problem becomes worse if you are carrying a loaded bag and need hip belt support. You’re fine if you opt for a smaller, higher-mounted daypack.

To control the exoskeleton, you can either dive into the app or use the single button on the right hip motor. I’m somewhat familiar with Hypershell’s long-press and short-press control system, but it’s not particularly intuitive. I won’t be the only one who turned on Hyper at an inopportune moment or turned it off entirely by accident. The app offers a much greater level of control, allowing you to easily select modes, adjust power ratios, and check battery life.

Power up

Having something else move your legs, or at least help you move them, is not a natural sensation, and no matter how many times I wore the X Ultra S, it took a good few minutes for me to adjust to it. But compared to previous generations, this exoskeleton looks better in almost every way. For older models, when I started walking, my legs would shake abnormally, and I could only be helped when I took a step. However, here, assuming you’re not trying to walk in Hyper Running mode – which will see you casing like a diver – there is a breakthrough in power assistance.

Walking doesn’t feel quite as natural, but the way the X Ultra S saves energy is much more intuitive. Stopping and starting feels nicer, and when I was wandering aimlessly waiting for someone, the system immediately noticed and backed off the power. When I took a step, the assistance increased accordingly, but for the first time, I felt in control rather than feeling like a beta test rider.
