2015-09-28 04:25:50 -0500 | asked a question | Turtlebot get stuck when no obstacles around Hello all, currently I am using a turtlebot for exploration (rtabmap for slam and frontier_exploration for exploration). The problem is, when the turtlebot drive on the inflation area and is given a goal in the opposite direction, it just get stuck like it cannot turn around or it thinks there are obstacles around. Does it have something to do with the base local planner? Thanks in advance. |
