+## What has changed
+
+We modified the joint limits in the panda_arm.xacro.
+More in detail they are increased/decreased by 0.1.
+This had to be done to never let the cartesian planner hit the limits again.
+The limits were always reached, as the planner includes them in his plannable value range.
