A stand-on land vehicle, for simulating snow skiing, features a side-by-side pair of platforms, coupled and supported (a) at the rear by an angled tilt-turn mount under each, integrated with a shared axle assembly fitted at its ends with a pair of rear wheels, located at opposite sides of the vehicle, and (b) at the front by a tilt-turn mount system including a strut/spacer framework attached to a pair of user handling bars, and to at least one front wheel, typically a roller, via an associated inclined swivel-caster type mount assembly. This novel combination accomplishes dual-platform tilt-turning in response to the user's body movements that simulates the superior snow-skiing technique of skewing the skis longitudinally for banked turns as in zig-zagging downhill. The invention actually enables sustained self-propulsion, zig-zagging on level concrete and paved surfaces, powered only by user body movements during turns and enhanced by low-friction roller-wheels for free-wheeling coasting on straight runs, and is thus capable of providing, on dry land, both recreational pleasure and highly effective training and practice for snow-skiing for snow skiers of all ages and skill levels.

A summer style ski having three different types of wheels aligned to allow the ski to travel on non-snow or ice surfaces and to create the feel of carving or turning on a paved surface.

Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

The invention discloses an exoskeleton (10) for a human person (8) for assisting and/or extending the range of motion and locomotion of the subject, and a method for operating and handling such an exoskeleton (10). The exoskeleton (10) is provided with a plurality of sections (12, 14, 16) and associated connecting joints (20, 24, 28) and can be operated in a walking mode and in a rolling mode. The lower leg sections (16) and/or the knee or second connecting joints (24) are associated with motor-driven wheels (32), which are inactive in a walking mode of the exoskeleton (10) when the person (8) is standing on the ground or moving by means of walking and/or stepping and/or climbing and/or running movements and are in a position at a distance from the ground and/or from the foot section (18) of the exoskeleton (10), and which are activated and/or motor-driven in a rolling mode of the exoskeleton (10) and are in contact with the ground.
