Abstract

A motorized articulated module comprises two elements that move with respect to one another, a linear actuator permitting motorization of the module and comprising a body and a stem able to move in translation with respect to the body along an axis, the body of the actuator connected to the elements by a connection having at least one degree of freedom in rotation, and two articulated rods associated with the actuator, connected to the stem of the actuator by a connection having one degree of freedom in rotation, the first articulated rod connected to the first element by a connection having at least one degree of freedom in rotation, the second articulated rod connected to the second element by a connection having at least one degree of freedom in rotation. An articulation comprising multiple modules and an exoskeleton comprising multiple articulations are provided.

Dependent claims

A motorized articulated module comprising two elements that are able to move with respect to one another, further comprising:

a first linear actuator permitting motorization of the module and comprising a body and a stem that is able to move in translation with respect to the body along an axis, the body of the first actuator being connected to each of the two elements by means of a connection having at least one degree of freedom in rotation,
two articulated rods associated with the first actuator, each connected, at a first one of their ends, to the stem of the first actuator by means of a connection having one degree of freedom in rotation, a second end of a first one of the two articulated rods being connected to the first of the two elements by means of a connection having at least one degree of freedom in rotation, a second end of a second one of the two articulated rods being connected to the second of the two elements by means of a connection having at least one degree of freedom in rotation.
