Hi all,

I´m trying to run some mapping experiments with a mobile robot on a Ubuntu 16.04 machine with ROS Kinetic and Gazebo 7.

What I did was to define a diff-drive with the following urdf:

and then, to run the simulation I use this launch file:

by doing so, I get a strange behavior, that is, the robot is loaded correctly but from the laser scan it seems that it´s not able to sense objects:

Can you please explain me what could be the problem, please?

Thanks!

Try the using the non-GPU version of the laser.

Hello! I did that, it didn't work as expected.

However, I solved it by reinstalling-updating the NVIDIA drivers. works like a champ! Thank you anyway!

Try the using the non-GPU version of the laser. Change the line

<sensor type="gpu_ray" name="head_hokuyo_sensor">

to

<sensor type="ray" name="head_hokuyo_sensor">

and replace

<plugin name="gazebo_ros_head_hokuyo_controller" filename="libgazebo_ros_gpu_laser.so">

with

<plugin name="gazebo_ros_head_hokuyo_controller" filename="libgazebo_ros_laser.so">
