Hi im currently trying to figure out how to check for collisions between a cylinder object that i will spawn in the collision objects topic and the already available octomap in the planning scene. I know you can do collision checking with the robot and collisionobj/octomap, but not sure about between collision objects/octomap.

One way i can think of is by attaching the cylinder collision object to the robot and then check for collisions with the octomap. Though maybe there is another way.

Im actually looking into this as well, have you been able to get any meaningful results? Im thinking of a simple precheck using an octomap and checking if a space is "occupied".

The problem seems to be I'm running Ubuntu as a virtual machine, which doesn't give gazebo enough juice or something. So if anyone runs into this problem, stop using a VM.

since doing a clean install of Indigo didn't solve the issue, it seems to me that I'm missing some essential package?

reinstalling ROS didn't help in any way, same result

I'm trying to reinstall ROS, maybe that will help

EDIT: that didn't help

So im busy setting up a proper simulation environment for my robot. During the process i added depth sensors in the URDF file of the robot and images come out great. Though pointclouds show me planes instead of points. So there is a problem somewhere.

To verify it was my problem only i opened up the turtlebot in gazebo and rviz and it shows me the same thing as for the robot i'm working on. So it is a problem for me in general, but I've no idea what it can be. Maybe i've failed to install an important part?

Anyone has an idea? Thanks in advance

For info, im on 14.04 and running Indigo
