Negative world bias: tracking failure in ORB-SLAM and ORB-SLAM3 on sequences where path is not planned by human. ORB-SLAM reaches the goal in none of the 25 considered sequences. ORB-SLAM3, an improved version, does manage to reach the goal in 8/25 sequences. Average sequence length is 13.48m. Average distance covered by ORB-SLAM is 1.38m, while that of ORB-SLAM3 is 9.33m.
