Travelling robot with obstacle avoidance system and balance control - has 2 sets of perpendicular longitudinal elements supported by legs which are lengthened and shortened by operating drives

摘要

The robot has longitudinal elements (10a, 10b; 14a, 14b) extending in 2 perpendicular directions (X, Y) and a movable body (18) displaced along the longitudinal elements (10a, 10b; 14a, 14b) via respective drives (32a, 32b; 24a, 24b). The longitudinal elements (10a, 10b; 14a, 14b) extending in each direction (X, Y) have leg sections (38a..38d; 46a..46d) which can be lengthened and shortened in a third perpendicular direction, under control of a third and fourth drive mechanism (40a..40d; 48a..48d), to allow an object in the path of an object to be avoided without a change in direction. Pref. 2 parallel longitudinal elements (10a, 10b; 14a, 14b) extend in each perpendicular direction (X, Y), each pair supported by a pair of legs (38a..38d; 46a..46d) at each end. ADVANTAGE - Allows obstacle to be avoided without change of direction of robot.
