Gazebo CMD_VEL (Slipping on Terrain) #139

Closed ptiwari0664 closed 5 years ago

ptiwari0664 commented 6 years ago

Hello Everyone!

I am trying to simulate catvehicle in gazebo. After a successful installation and with launching: roslaunch catvehicle catvehicle_skidpan.launch (urban.world) and gzclient, I am clearly able to see the vehicle in the world. After this I published a command velocity of linear.x = 3.0 to the topic /catvehicle/cmd_vel or /catvehicle/cmd_vel_safe rostopic pub /catvehicle/cmd_vel geometry_msgs/Twist "linear:
x: 3.0 y: 0.0 z: 0.0 angular: x: 0.0 y: 0.0 z: 0.0" -r 10

Expected Behavior

The vehicle is able to move but the movement should be fast as, its around 10KMPH.

Actual Behavior

The vehicle movement is really slow around 0.6 m/s.

Specification

Ubuntu version: 14.04 LTS ROS Version: Indigo Gazebo version: 7.0

Thanks in Advance !!!!!

I have this same issue, although I am on 16.04 and kinetic. Same symptoms. @ptiwari0664 , have you had any breakthrough? Thanks

I have also got the same problem. Is it related to simulation physics or something else? Thanks in advance if anyone has got the answer.
