Exemplary embodiments pertain to the art of exoskeletons. The shift towards deep-space, long-duration missions, and the increase in commercialization of space travel motivate the need for training, maintenance, and physical fitness technology. The reduced gravity experienced during space travel, especially during such longer duration missions causes muscle and bone atrophy in humans, which can be reduced by employing exercise. The existing technology for exercise includes a combination of several machines or apparatus with limited capability. The art would well receive a single solution for exercise, training, virtual escape, and lift assistance, solving a broad range of technical problems encountered during long duration space missions.
In one embodiment, an exoskeleton system includes an exoskeleton securable to a user, and a control system operably connected to the exoskeleton. The control system is configured to selectably operate the exoskeleton in two or more preconfigured operating modes.
Additionally or alternatively, in this or other embodiments one of the two or more preconfigured operating modes is an activity simulation mode wherein the controller commands the exoskeleton to provide resistance and/or feedback to the user to simulate an activity.
Additionally or alternatively, in this or other embodiments another of the two or more preconfigured operating modes is strength enhancement of the user.
Additionally or alternatively, in this or other embodiments the activity is one of walking running, swimming or cycling.
Additionally or alternatively, in this or other embodiments one of the two or more preconfigured operating modes is simulation of a low or zero gravity environment.
Additionally or alternatively, in this or other embodiments a virtual reality apparatus is configured to be worn by the user and operably connected to the control system.
Additionally or alternatively, in this or other embodiments the control system is secured to the exoskeleton.
Additionally or alternatively, in this or other embodiments the exoskeleton includes a plurality of actuators operably connected to and controlled by the control system.
In another embodiment, a method of operating an exoskeleton includes an exoskeleton securable to a user, and selecting one of two or more preconfigured operating modes of the exoskeleton via user input to a control system operably connected to the exoskeleton.
Additionally or alternatively, in this or other embodiments one of the two or more preconfigured operating modes is an activity simulation mode wherein the controller commands the exoskeleton to provide resistance and/or feedback to the user to simulate an activity.
Additionally or alternatively, in this or other embodiments another of the two or more preconfigured operating modes is strength enhancement of the user.
Additionally or alternatively, in this or other embodiments the activity is one of walking running, swimming or cycling.
Additionally or alternatively, in this or other embodiments one of the two or more preconfigured operating modes is simulation of a low or zero gravity environment.
Additionally or alternatively, in this or other embodiments a virtual reality apparatus is configured to be worn by the user and is operably connected to the control system.
Additionally or alternatively, in this or other embodiments the control system is secured to the exoskeleton.
Additionally or alternatively, in this or other embodiments the exoskeleton includes a plurality of actuators operably connected to and controlled by the control system.

The exoskeleton 10 of the present disclosure incorporates haptic feedback, virtual reality simulation, and smart health monitoring, as discussed with reference to the modes. Exoskeleton 10 is programmed to not only reduce loads to create augmented strength for the user 12, but to create resistance against movement, simulating realistic, even Earth-like, activities. This single machine can provide a wide variety of simulated exercises and hobbies, health and exercise tracking, visually and physically realistic on-mission training exercises, augmented strength upon arrival to space destination, and a virtual escape from space to better crew moral and mental health, depending on an operational mode or program selected at the control system 36.
In a first operating mode, the exoskeleton 10 is utilized to enhance strength by commanding the actuators 34 to move the limbs 18 in cooperative movements with the user 12. For example, when the user 12 raises an arm 20 or leg 22, the actuators 34 are commanded to concurrently move the respective limbs 18 of the exoskeleton 10 in the same direction. Thus, the force of the actuators 34 is additive to the force applied by the user 12. This strength-assist mode decreases resistance for the user 12 and is useful for working in a space environment and/or on Earth.
In a second operating mode, the exoskeleton 10 is utilized to simulate exercises, hobbies or other activities. For example, as shown in
When combined with the use of a virtual reality (VR) device 38 such as a headset and/or sound, the user may perform selected exercises or other activities in a virtual environment remote from the space environment, which has benefits in claustrophobia and./or boredom relief and other mental health benefits to the user 12.
In a third mode, the exoskeleton 10 may be utilized to simulate low or zero gravity while on Earth allowing the user 12 to train for tasks to be performed in space utilizing the exoskeleton 10. In this mode, the exoskeleton 10 provides feedback and/or strength enhancement needed to simulate the low or zero gravity environment as well as resistance and/or feedback to simulate the task the user 12 is training to perform. In any mode of operation of the exoskeleton 10, the use of the exoskeleton 10 may be combined with the use of the VR device 38 and/or sound for increasingly immersive experience for the user 12 while performing a selected activity.
Training can be completed while on the mission. That is, extravehicular activities (EVAs) are typically rehearsed prior to execution. If the user 12, an astronaut or space traveler, is on the space station, in a habitat, or in a space transport vehicle, etc., he/she can use the exoskeleton 12 to rehearse the EVA. Using the exoskeleton 12 in this manner can reduce risk and increase mission success. Furthermore, the exoskeleton 12 may be utilized to learn new skills or other activities.
The exoskeleton 10 system disclosed herein is a multi-purpose, multi-use tool, which when compared to existing tools and methods offers far increased and unique capabilities, while still realizing a reduction in complexity for the user and also a reduction in system volume.
