Hello everyone,

i using the robotino with kinetic . I use the following robotino package from this source for my project. I started the with roslaunch robotino_node robotino_node.launch and than i get some error in my launch file.

ERROR: cannot launch node of type [robotino_node/robotino_node]: can't locate node [robotino_node] in package

What is the problem and how can I solve it? Please let me know, when you need more information about this problem.

regards, Markus

thank you for your answer. My robot localization node looks same as yours! But I have on the question, why are you using

Gmapping combine robot localisation or robot pose ekf Hello everybody, i am working on a project with an omniwheel robo

So i found my mistake, it was really the problem about to set the right franes. So it works fine! Thank you

I used on my pointcloud to laserscan the base_kinect_link, which is 0.1 m above over the base_link How high would you r

I think I used the wrong base_frame. I used the base_footprint and it works better, but i get sometimes the same error

Hello everybody,

I would like to use the gyro sensor MPU 6000, which is used on the robotino. It is possible to integrate this gyro sensor in ROS? If so, is there a manual?

Regards, Markus

I use the following api from the robotino: here Also i write my own header and my own cpp-File and include it on the ro

The frames setup is: odom_frame = odom | base_frame = base_link | map_frame = map

The frames setup is: odom_frame = odom base_frame = base_link map_frame = map

Hello,

i have a Microsoft Kinect sensor and i am using the freenect driver to use it, Then I transform my pointcloud to a laserscan and show it on my base_link frame. I get the following error:

Transform failure: Lookup would require extrapolation into the past. Requested time 1594648338.669846591 but the earliest data is at time 1594648338.900337345, when looking up transform from frame [kinect_depth_optical_frame] to frame [base_link]

On the Image you can see the current Transformation tree. When you need some information than please tell me.

Regards, markus

I already use 100 Hz on my static_transform_publisher. I use the answer above and it works! Also thank you for your ans

thank you it works!
