A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.

A robotic vehicle for traversing surfaces is provided. The vehicle is comprised of a chassis supporting a magnetic drive wheel for driving and steering the vehicle and a stabilization mechanism. The magnetic wheel comprises two flux concentrator yokes and an axially magnetized hub extending therebetween. The hub includes a central housing configured to house a sensor probe and enhance the magnetic pull force of the wheel by providing a continuous pathway of high magnetic permeability material for magnetic flux to flow axially through the drive wheel. The stabilization mechanism comprises a front and rear facing support element moveably coupled to the chassis and configured to contact the surface and move symmetrically relative to the chassis thereby maintaining the vehicle and probe normal to the surface and providing stability to the vehicle while traversing surfaces regardless of surface curvature and vehicle orientation.

A multi-leg independent mobile carrier device, comprising: a base (1), a traveling mechanism (2), and a posture adjustment mechanism (3). The base (1) is used for carrying a human being or an object. The traveling mechanism (2) comprises a driving unit (21) connected to the base (1) and a connecting rod unit (22) rotatably connected to the driving unit. The traveling mechanism (2) is used for driving the base (1) to travel and get over any obstacles. The posture adjustment mechanism (3) is connected to the base (1) and used for keeping the human being or object balanced. The multi-leg independent mobile carrier device integrates a traveling mechanism and a posture adjustment mechanism. The posture adjustment mechanism is used for keeping the base balanced all the time and the traveling mechanism is used for driving the entire device to travel and turn around more flexibly. Therefore, the technical problem of a carrier device being unable to satisfy requirements of good obstacle performance, comfortable riding experience, and flexible traveling is effectively solved. The obstacle crossing ability of the multi-leg independent mobile carrier device is enhanced, and user experience is improved.

The present invention relates to a device and method for transferring rotational, mechanical motion into sinusoidal wave-like motion. The device comprises at least one motor, generating rotational movement around a first Cartesian axis; an elongated rod, curved in the form of a helix, substantially aligned along said first Cartesian axis, and rotated by the at least one motor; a surface comprised of discrete, connected hollow elements, wherein: (i) the curved rod is interlaced within the said discrete hollow elements, such that the surface is undulated, and the rotation of the curved rod dynamically changes the surface's shape, moving the discrete hollow elements along a second perpendicular Cartesian axis, thus creating a wave like motion; (ii) the width of each said discrete hollow element is slightly larger than the diameter of the helix-shaped rod, so as while rotating, the elongated rod is freely movable within the cavity of the discrete hollow elements, along the third perpendicular Cartesian axis; (iii) the said surface interacts with the surrounding medium or base-surface upon-which the device is moving, wherein said interaction is generated by said wave-like motion, such that the said interaction creates a propelling force that drives said device forward or backward along the said first Cartesian axis.
