An obstacle traversing wheel assembly includes a primary wheel (121) having an even number, at least four and preferably six or eight, of secondary wheels (33) mounted at equal-spaced, fixed locations thereon. The diameter of each secondary wheel is greater than is the distance between locations, and adjacent secondary wheels (33a, 33b) are arranged to roll in separate, parallel paths. The primary wheel (121) is mounted on a yoke (127) that supports a load-bearing frame (125).

Le diamètre de chaque seconde roue est supérieur à la distance séparant les emplacements et des secondes roues adjacentes (33a, 33b) sont disposées de manière à rouler sur des voies séparées et parallèles. La première roue (121) est montée sur une fourche (127) supportant un cadre porteur (125).
