A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

A multi-wheel truck that minimizes wheel interactions with discontinuous and uneven surfaces. The truck provides a suspension system that absorbs impact force caused by uneven surfaces and a unique attack angle that allows obstacles to be traversed when approached from a wide range of angles.

Provided herein is a training device configured to allow a user to simulate all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces. The device is equipped with a braking system that allows the user to slow down the speed of travel when the moving direction changes from forward to sideways, thereby simulating the act of slowing down on a slope by turning a ski or snowboard. The braking effect is further enhanced when the ski or snowboard is tilted towards the uphill direction, further simulating the actual movements of skiing or snowboarding on snow. The braking system may include one or more mechanisms to amplify the force applied to the brake cables. An optional steering bar may be provided with handles that are positioned ahead of the bar to simulate the planting of ski poles prior to or during a turn.

Disclosed is a self-balancing vehicle including a left housing assembly, a right housing assembly, a left wheel train, a right wheel train and a rotation mechanism. The left wheel train is connected with the left housing assembly. The first end of the rotation mechanism is connected with the right wheel train and the right housing assembly, and the second end of the rotation mechanism is inserted into the left housing assembly and rotationally connected with the left housing assembly. The rotation mechanism is just arranged in the right housing assembly, but connected with the right housing assembly and the right wheel train respectively, thus reducing the strength requirements of the self-balancing vehicle on the left housing assembly and simplifying the components of the left housing assembly.

Motorized skating systems and methods for controlling the systems are disclosed. One exemplary system may include a primary skate and a secondary skate. The primary skate may include a sensor configured to detect a tilting signal. The primary skate may also include a first processor. The processor may be configured to determine a first control signal for moving the primary skate based on the tilting signal and determine a motion signal for moving the secondary skate based on the first control signal. The primary skate may further include a first communication interface configured to send the motion signal to the secondary skate. The secondary skate may include a second communication interface configured to receive the motion signal from the first communication interface. The secondary skate may also include a second processor configured to determine a second control signal for moving the secondary skate based on the received motion signal.
