Acceleration Noise in Gazebo
Hi All,
I'm writing my own planner in ROS and I'm trying to test it using Gazebo. I'm observing really weird behaviors from Gazebo. For example some times I just send some simple velocity commands like Twist::linear.x = 1. Twist::angluar.z = 0, which is supposed to drive the robot in a straight line, but some times robot turns slightly. Also when I send rotational velocities the turning angle varies alot among different runs. I'm using the Pioneer 3dx model which I downloaded from https://github.com/RafBerkvens/ua_ros... . I think it's using "differential_drive_contoller" plugin to drive the robot. When I use the erratic_teleop_keyboard to drive the robot the same strange behavior happens. I'm using ROS Indigo. Any help would be highly appreciated.
Is it possible that gazebo is properly modeling the inaccuracies in the real robot?
I don't think the real robot is that inaccurate. Its behavior is so unreliable.
Does anyone know about any good gazebo model of p3dx? I've tried the p2os model as well and it's not working for me.
