A mobile platform intended for civilian, industrial, research or other use. An ambulation system or mobile platform such as for traveling over uneven terrain includes one or more leg arrangements attached to a main body or chassis. In an embodiment, a leg arrangement comprises one or more legs, such as legs that rotate in the same and singular direction around their respective rotary joints when the vehicle is moving in a single direction. The rotational axis for both legs is located near each other and preferably coaxially and allows ground contact of two or more legs at all times.

A robotic vehicle chassis is provided. The robotic vehicle chassis includes a first chassis section, a second chassis section, and a hinge joint connecting the first and second chassis sections such that the first and second chassis sections are capable of rotation with respect to each other in at least a first direction. The vehicle includes a drive wheel mounted to one of the first and second chassis sections and an omni-wheel mounted to the other of the first and second chassis sections. The omni-wheel is mounted at an angle orthogonal with respect to the drive wheel. The hinge joint rotates in response to the curvature of a surface the vehicle is traversing.

A system for preventing discomfort to a user of a robotic exoskeleton (200) determines the existence of an exoskeleton operating condition which has the potential to cause at least one of a discomfort or an injury to a user (204) when the exoskeleton is being worn by the user. Responsive to the determining, an exoskeleton control system (224) selectively controls at least one viscous coupling (208, 210) disposed at an interface location (201, 203) of the exoskeleton where a physical interaction occurs between a portion of the user and a portion of the exoskeleton when the exoskeleton is in use. The control system selectively varies a viscosity of a fluid (216) comprising the viscous coupling to control the stiffness of the interface.

The invention relates to a spherical wheel (10) for moving a vehicle, and to a vehicle implementing the wheel, wherein the wheel (10) is rotated by a shaft (12) that is rotatable about an axis (14). According to the invention, the wheel (10) includes two hemispherical shells (15, 16), the surfaces of which follow the spherical surface of the wheel (12) and each of which is delimited by a plane (17, 18). The hemispherical shells (15, 16) are each pivotable, via a pivot linkage, relative to the shaft (12), an axis (21, 22) of each of the pivot linkages being perpendicular to the plane (17, 18) of the hemispherical shell (15, 16) in question. The planes (17, 18) delimiting the two hemispherical shells (15, 16) intersect.
