2016-09-12 01:51:20 -0500 | asked a question | Turtlebot spinning in place + not going straight when speeding up simulation Hello, As I show in the videos above, the Turtlebot is spins around itself a bit, which could affect the direction when I try to go straight. When the real time factor (simulation speed) is normal the robot makes an acceptable straight line, but when the simulation is set to maximum the robot clearly turns to the right. This strange behaviour does not happen in empty worlds, just when the robot is inside a model. Any possible solution to this issue?
