Title
(EN) METHOD OF TRAVERSING DIFFICULT TERRAIN
(FR) PROCÉDÉ DE TRAVERSÉE DE TERRAIN DIFFICILE
Abstract
(EN)
A method of operating a mobile remotely controlled ground robot in difficult terrain. Rear driven tracked arms of the robot are pivoted rearward and upward to trail main driven tracks of the robot at a fixed angle relative to and above the ground. The main tracks of the robot are driven forward to traverse the ground. An obstacle is traversed by driving the main tracks to traverse the obstacle pivoting the forward end of the robot upwards and at least one of the rear driven tracks are driven and engaging the ground and/or obstacle to advance the robot forward over the obstacle and to prevent the robot from tipping over backwards.
(FR)
La présente invention concerne un procédé de fonctionnement d’un robot terrestre télécommandé mobile dans un terrain difficile. Des bras à chenille entraînés arrière du robot sont pivotés vers l’arrière et vers le haut pour suivre les chenilles entraînées principales du robot à un angle fixe par rapport au sol et au-dessus de celui-ci. Les chenilles principales du robot sont entraînées vers l’avant pour traverser le sol. Un obstacle est traversé par l’entraînement des voies principales pour traverser l’obstacle faisant pivoter l’extrémité avant du robot vers le haut et au moins l’une des chenilles entraînées par l’arrière est entraînée et mise en prise avec le sol et/ou l’obstacle pour faire avancer le robot vers l’avant sur l’obstacle et pour empêcher le robot de basculer vers l’arrière.
