I am using ROS Toolbox™ Support Package for TurtleBot based Robots. I installed virtual machine with Linux (ROS and Gazebo in it) and I succesfully connected with robot by Matlab.
My question is: is this normal, that simulated Turtlebot, which should be geometrically ideal, don't move in straight line?
Like in tutorial I just set linear velocity in X axis and send it request to move for a few second, but its path is not straight, and it starts slowly turn to one side. Should it be like this? I understand it could happend in real robots, where you have to implement some PID controller, but should the robot behave like this in simulation?
Thanks for any help.
