Vastnaut One 4×4: an AI exoskeleton that takes the load on itself

The idea of “strengthening” a person with the help of technology remained either a military development or a medical tool for a long time. Vastnaut tries to bring this concept into everyday life: Vastnaut One 4×4 is not an experimental prototype, but a consumer device capable of redistributing the load on the legs in real time. In fact, it is about transferring part of the work of muscles and joints to electronically controlled mechanics.

Active help instead of passive support

The design is based on a system of four motorized nodes – two for each leg. Each of them is equipped with a separate drive with a power of 400 W, which allows the device not just to “unload” the user, but to participate in movement synchronously.

The key difference from simpler solutions is the presence of an intelligent control system. VastSynergy algorithms analyze telemetry from sensors in real time: from basic parameters such as weight and height to dynamic characteristics – step rhythm, joint flexion angles and current load.

Due to this, the exoskeleton does not impose a fixed model of movement, but adapts to the user and the environment. When climbing, it increases the torque, on a flat surface it minimizes interference, maintaining a natural gait. This approach reduces the risk of stress on the joints, which is especially important for long-term loads.

Materials and ergonomics

One ​​of the key issues with wearable amplifiers is their weight. If the device is heavy, it partially negates its own benefit. In Vastnaut One 4×4, this task was solved due to the extensive use of carbon fiber: more than 86% of the structure is made of carbon.

As a result, the weight of the device is only 2.7 kg – an indicator that makes it significantly less burdensome compared to most analogues. This allows you to use the exoskeleton not episodically, but for several hours without significant discomfort.

In addition, the device is protected according to the IP54 standard, which makes it suitable for use outdoors – in dust, high humidity and light rain.

Autonomy and usage options

The exoskeleton is designed for about 4.5 hours of active work, which is equivalent to a distance of about 20 km with motion support. For longer routes, replaceable batteries are provided, which allow to expand the range of application.

Usage options go far beyond tourism. Yes, the device looks logical in the mountains or on rough terrain, but it is no less relevant in everyday tasks: carrying heavy loads, working on the site, long walks or climbing stairs.

Separately, it is worth noting the potential value for people with increased load on the joints – the exoskeleton can act as an auxiliary tool that reduces wear and tear on the knees and lower back.

Device economics: investing in load, not entertainment

Vastnaut One 4×4 is priced at $1,300 for pre-order, rising to $1,900 retail. At first glance, the amount looks high, but the device does not belong to the category of entertainment, but to tools for optimizing physical activity.
