VR exoskeleton from Holotron

The German company Holotron has developed a virtual simulator that transmits interaction between objects of the virtual environment to a person in the real world through an exoskeleton.

Basically, this is a device designed to simulate the interaction of the virtual world with human feet. The simulator consists of two overall frames for the legs and a support frame behind the back. Each leg has two motors: one is responsible for bending and extending the knee, and the second is designed for the hip. When walking normally, a person can move his legs freely, but when he comes into contact with objects, for example, with a large ball used in the demonstration program, the motors transmit force to the leg. The maximum force is 150 newton meters, but it can be programmatically limited for work safety.

The main feature of the exoskeleton is that it does not stand on the floor, but is suspended on the wall, and it is not fixed on it, but fixed through the Stewart platform. In the initial position, the exoskeleton is located parallel to the wall, but due to the extended legs of the platform, it can be tilted in the desired direction. The developers used this for several applications, including simulating reduced gravity and for a more realistic ride on a virtual longboard.

In its current form, the exoskeleton is an early prototype worth 55 thousand euros, assembled from simple components. In particular, a significant part of the platform body is assembled from wood. In the future, engineers plan to create a more compact version made of metal, which will not be mounted on the wall, but installed on the floor and hung on a floor suspension.
