Abstract:
A joint attachment system for a reconfigurable truss includes a first joint attachment having a first pivot axis and a second joint attachment having a second pivot axis. The first joint attachment and second joint attachment form a concentric spherical joint linkage when attached to a first body member and a second body member, respectively. The first pivot axis of the first joint attachment intersects the second pivot axis of the second joint attachment at a single point X which defines a center of the concentric spherical joint linkage. The concentric spherical joint linkage is configured to allow the addition of one or more joint attachments and body members to the truss node. In addition, the concentric spherical joint linkage is configured to allow the removal of one or more joint attachments and body members from the truss node.

Abstract:
A robot comprising an arm extending between a base and an attachment for an end effector, the arm comprising: a first arm part; a second arm part distal of the first arm part; and a joint whereby the first and second arm parts are coupled together, the joint permitting the first and second arm parts to rotate relative to each other about at least two mutually offset axes; a control rod attached to the second part of the arm at a location spaced from the first and second axes, the control rod extending distally of that location along the first arm part; and a drive mechanism for driving the control rod to move relative to the first arm part and thereby alter the attitude of the second arm part relative to the first arm part.
Abstract:
L'invention concerne un dispositif d'entraînement d'un objet (1 ) suivant au moins trois mouvements de rotation combinés. Ce dispositif comporte des premier, deuxième et troisième arbres (13, 32, 42) creux et coaxiaux d'axe X1 destinés à être respectivement entraînés en rotation, par rapport à l'axe X1 , par des premiers, des deuxièmes et des troisièmes moyens moteur (4, 5, 6), indépendamment les uns des autres. Le premier arbre présente une extrémité libre portant une première surface de sortie sensiblement plane, de contour général circulaire, et orientée perpendiculairement à un axe X2 coupant l'axe X1 en définissant un angle α. Des moyens de liaison mécanique sont prévus pour relier cinématiquement le deuxième arbre à un support (8) monté libre en rotation sur la première surface de sortie, tandis qu'un renvoi intermédiaire (50) d'axe X2 est prévu pour relier cinématiquement le troisième arbre à l'objet, ce dernier étant monté dans le support en étant libre en rotation autour d'un axe X3. En outre, il est également prévu que l'axe X3 présente un angle α par rapport à l'axe X2, les trois axes X1 , X2 et X3 se coupant en un point unique. Le dispositif comporte notamment un passage central reliant les arbres à l'objet, ce dernier étant monté en prise avec un premier engrenage du renvoi intermédiaire orienté en direction de l'axe X2.

Robot wrist (7), for a robot arm (5), which includes a tilt housing (8) that is arranged to rotate about a first axis (C) and which comprises a first motor (10) and a first gear assembly (11) which cause the tilt housing (8) to rotate about said first axis (C), where the output shaft (15) of the first motor (10) is arranged to be coaxial with said first axis (C).
Abstract:
A mechanism for orienting an end member utilizes paired five-bar linkages wherein two joints on each five-bar linkage may be actuated. Preferably the actuators are mounted at the base-link of the five bar linkages, such base-links being collinearly aligned. Two or three rotational and one translational degree of freedom are available. This mechanism in its three or two degrees of rotational freedom variants have exceptional motion range, free of singularities, superior structural properties, and is easy to manufacture. This orienting mechanism can be mounted as an end member on a positioning mechanism having a four main links wherein three joints are actuated. The diagonally opposed joints of the positioning mechanism are respectively spherical and revolute. This positioning mechanism can operate with two actuators that are grounded and one that is elevated. In all cases sensors may be substituted for, or used in conjunction with, actuators to provide an apparatus useful, interalia , in the telerobotics and virtual reality fields.

Abstract:
A coupling comprises at least an inner annular member, an intermediate annular member and an outer annular member. The intermediate and outer annular members are positioned with respect to one another and with respect to the inner member by driven gear wheels acting on gear teeth associated with the inner and intermediate members. By coupling the outer member of one coupling of a series of couplings to the inner member of the next coupling of the series, a robot arm may be constructed in which drive can be transmitted from one end of the series to the other. By changing the potions of the members of the couplings in the series, the orientation of the robot arm may be change
