The invention provides an omnidirectional treadmill system that uses an inner core which is inflated within a tread membrane. On the outside surface of the inflated inner core are ball casters which push outward against the interior of the membrane, resulting in a low friction barrier between the inner core and the inside surface of the tread membrane. The tread membrane rests on a sphere directly below the user in the center of the device. When the sphere is rotated it drives the tread around the stationary inner core. The sphere rotation is accomplished using a holonomic drive system such as motorized omni wheels. The device uses an enclosure which encircles the tread area. The enclosure serves two purposes: to enhance safety of the user and to provide a surface for image projection to the user in virtual reality applications.

A motion device for a virtual reality interaction includes a core, a running belt carried by the core and a frame. The running belt is configured to wrap the core and capable of sliding on the outer surface of the core. The running belt includes a number of running belt units. A surface of each running belt unit facing the core is provided with a number of grooves, and each groove of each running belt unit is connected with a corresponding groove of an adjacent running belt unit through an elastic strap. The frame is located at a periphery of the running belt and is configured to carry the running belt and the core. A number of first balls are arranged between the frame and the running belt.

An omnidirectional treadmill environment simulator is disclosed. The omnidirectional treadmill environment simulator includes a circular simulator stage area, a plurality of transport mechanisms that maintain an object at or near the center of a circular simulator stage area and at least one processor. The processor is configured to collect position data of the object and process the position data to control the transport mechanisms. Also included is a receiver for receiving data from a remote location and a terrain analysis computer for processing the data received from the remote location. The terrain analysis computer collects the data received from the remote location to form an accurate simulation of an upcoming condition at the remote location. The omnidirectional treadmill environment simulator includes a transmitter for transmitting the position data to a remote location.

A muscle-building apparatus for building the muscles of a user performing a physical exercise, comprising a frame on which are assembled a treadmill which is displaceable in a longitudinal direction and in opposite senses, a force generator that supplies an adjustable pushing or dragging force, and a swivelling support mechanically coupled to the force generator for the user to perform a pushing or dragging exercise on the swivelling support.

A device for visual walking includes an omnidirectional exercise machine and foot wearable devices. A method for visual walking is applied to the device for visual walking. When a user wears the omnidirectional exercise machine and uses the loading frame to adjust a height of the omnidirectional exercise machine, and wears the foot wearable devices to stand and run on a running plate, human body posture data is obtained by tracking a human body torso. Then displacement data of left and right feet is obtained by tracking the feet. A virtual position and a movement speed of the feet are respectively obtained according to the displacement data, the leg posture is inferred by the IK algorithm according to the virtual position and the walking action of the virtual character is controlled according to the human body posture data, the movement speed of the feet, and the leg posture.

The present invention discloses a roller-type omnidirectional physical exercise platform, mainly including a housing, a plurality of groups of alternately-placed spiral rollers disposed inside the housing, a motor configured to drive the spiral rollers. The spiral rollers include clockwise spiral rollers and counterclockwise spiral rollers. Roller bodies of the clockwise spiral rollers are obliquely embedded with rotatable wheels at particular angles. Two ends of the roller are mounted with gears and bearings providing a support function. The counterclockwise spiral roller is mirror-symmetrical with the clockwise spiral roller. The present invention presents an active omnidirectional physical exercise platform. Compared with a passive omnidirectional exercise platform, a human body does not need to be strapped, thereby providing more real movement experience, effectively resolving a problem that movements in a virtual space are limited by a real space, and achieving features such as low noise and a slim machine body.

A treadmill is provided. The treadmill includes a frame; a first side support coupled to and extending substantially vertically upwards relative to the frame; a second side support coupled to and extending substantially vertically upwards relative to the frame; and a handrail assembly having a first side coupled to the first side support and a second side coupled to the second side support, each of the first and second sides of the handrail assembly comprising upper and lower members vertically spaced from one another and collectively providing a plurality of hand placement positions including at least two substantially horizontally aligned hand placement positions and at least one primarily vertically aligned hand placement position thereby allowing a plurality of exercises/uses of the treadmill.

A motor driven omnidirectional treadmill that allows users to walk, jog, or run in any direct ion. When the treadmill is coupled with computer-generated immersive environments users can maneuver their way on-foot through 360-degree VR environments of infinite expanse and scope.

A treadmill exercise apparatus which accommodates displacement of the moving treadmill deck about the vertical axis and the longitudinal axis, and optionally about the lateral axis, simultaneously.

An omnidirectional treadmill platform includes a splicing floor, an omnidirectional driving base and a floor removing/splicing actuator. A plurality of omnidirectional wheels are arranged in the driving base. The splicing floor is placed on the omnidirectional wheels. A user moves on the splicing floor, and the omnidirectional wheels of the driving base cause the splicing floor to move in a direction Opposite to the movement direction of the user thus enabling the user to experience unlimited free movement, while in reality remaining in place. The splicing floor is formed by splicing a plurality of splicing blocks. The floor removing/splicing actuator removes and splices the splicing blocks at right positions, recycling splicing blocks and achieving the unlimited extension of the splicing floor. The new platform provides unrestricted movement and variable ground surface simulation irrespective of turn radius with near-negligible inertia force without the use of special footwear.
