TF question about robot arm
Hi all, I have Groovy, a pincher arm, and turtlebot. I got success in "rosrun tf tf_echo base_link gripper_link", which shown TF data. But these data never change in accordance with time, though I changed the pose of gripper sometimes. Is it problematic? In my guess TF data should change and tell me the real-time pose of gripper. I don't know whether it's problem in URDF model issue(maybe URDF fails to connect with arm?). Thanks so much!
