I've commanded the robot to go to the green arrow position/rotation, so it went there and started rotating CCW until it got near the upper wall, then it got stuck in that position. The question is why it don't go a bit forward so it can complete the rotation? Which parameters can be changed so that it better behave in situations like that?

Update: It keeps writing in the logs:

[ INFO] [1501263591.230230037]: Got new plan [ WARN] [1501263591.260831641]: Invalid Trajectory 0.000000, 0.000000, 0.150000, cost: -6.000000 [ WARN] [1501263591.260927725]: Rotation cmd in collision [ INFO] [1501263591.260981225]: Error when rotating.

and after some seconds:

Currently we have recovery_behavior_enabled = true and clearing_rotation_allowed = false

I'll try to enable that, but that behavior has given me problems in the past (like colliding with walls). However, I can

I'm trying to calibrate a single camera using cameracalibrator, as explained in http://wiki.ros.org/camera_calibratio... Despite being able to see the camera using rosrun image_view image_view image:=/camera/image_raw, I cannot start cameracalibrator. After issuing rosrun camera_calibration cameracalibrator.py --size 9x6 --square 0.05 images:=/camera/image_raw camera:=/camera, I get the following output:

('Waiting for service', '/camera/set_camera_info', '...')
OK
init done

The window appears, but contents are not draw (all the answers I've found so far are related to set_camera_info not being provided, which is not my case). There's no video feed nor slider controls when I use that command. How do I solve that? This is using Kinetic on Ubuntu 16.04

If it helps:
