Abstract:
An equipment-carrying crawler (20) includes a rolling track (44) and a structural support (70). The structural support (70) supports equipment (16). Lifting magnets (72) are coupled to the rolling track (44) and to the structural support (70). The lifting magnets (72) are configured to oppose each other, lift the structural support (70), and aid in the translation of the rolling track (44).
Abstract:
Disclosed is a crawler robot which, even of a small size, can climb over a high step and which can perform various aspects of operations. Rollers, are arranged at apexes of triangular frames, and elastic crawlers are wrapped around the rollers, with the two frames being connected by a central support shaft. Rotatably provided to the central support shaft is a one-joint link (4) composed of a first link (23) and a second link (24) connected together by a rotation shaft. An end portion of the second link is rotatably connected with a front shaft of a subordinate crawler device equipped with crawlers wrapped around rollers. As a result, the crawler robot is composed of a triangular crawler device (2) and the subordinate crawler device (3) connected together by the one-joint link (4). The crawler robot can be operated by rotating and bending the link and by rotating the crawler devices in arbitrary directions.
Abstract:
Die vorliegende Erfindung betrifft einen Unterwagen (1) eines Krans mit einem Raupenfahrwerk (3), das einen Fahrwerksrahmen (4) und vier Einzelraupenwerke (5) aufweist, die an dem Fahrwerksrahmen (4) gelagert sind. Erfindungsgemäß zeichnet sich der Unterwagen (1) dadurch aus, dass der Fahrwerksrahmen (4) aus zwei durchgehenden Querträgern (7), an deren Enden jeweils eines der Einzelraupenwerke (5) befestigt ist, und aus einem Rahmenmittelstück (6), das die beiden Querträger (7) miteinander verbindet, besteht.
Abstract:
A self-propelled articulated continuous haulage system (1) comprising an elongated articulated body made up of a plurality of support frames (2) aligned in end to end abutting relationship. A conveyor system (80) is carried by and supported centrally on the support frames. The haulage system is characterized by traction means in the form of a pair of endless traction chains (7) carried on opposite sides of the support frames and spanning the length of the body, the chains engaging the ground in an operative condition of the system, and drive means (5, 6) for driving the chains to provide tractive and steering effort for the system.
Abstract:
Une vitesse odométrique primaire est mesurée par un capteur (20) sur un organe odométrique (4) roulant sur le terrain (10). Elle est corrigée par des moyens de calcul (26) pour tenir compte de l'inclinaison du terrain en son point de contact (16) avec cet organe. Cette inclinaison est mesurée à l'aide de capteurs d'efforts (22) mesurant par exemple les efforts appliqués à l'ensemble de cet organe. Une centrale inertielle fournit l'orientation et les vitesses angulaires du véhicule. Application à la navigation de robots tout-terrain.
Abstract:
A disaster relief robot and its operation controller. When relief goods, medicines, foods, etc., are transported outdoors to the site of disasters such as earthquakes, heavy rainfalls, landslides, etc., at the time of a wide area disaster, the present invention can prevent accidents such as the drop from cliffs, etc., and can secure also safety of an operator. To this end, track frames (16) of a crawler are fitted pivotally to the right and left sides at both of the front and rear portions of a robot body (10). The distance (L) between the pivots of front and rear crawlers (12F, 12R) is such that the maximum loci (CF, CR) of the front and rear crawlers may not meet, and the centroid (G) of the robot body exists at the intermediate position of the distance (L). The present invention proposes also various kinds of operation controllers.
