[Task1]: The contact between UAV and Truck seems wired in the motion tracking of UAV #80

Open tongtybj opened 8 years ago

tongtybj commented 8 years ago

I wrote a basic motion tracking code based on the PID feed-back control and truck trajectory feed-forward control. Both control part are using the ground-truth value(position of UAV/Trcuk).

Most part of motion tracking seems good. You can try the "motion_tracking" branch in my repository(tongtybj). step1: catkin build "jsk_mbzirc" step2: roslaunch jsk_mbzirc_tasks jsk_mbzirc_task_1.launch use_ground_truth:=false gui:=true step3: roslaunch jsk_mbzirc_tasks task1_motion_tracking_test.launch

The moment of contact between UAV and truck heiport seems wired...

The reasons I think is, 1) The relative speed between truck and UAV is not zero, this is based on the assumption that gazebo is totally right, and the "wired" contact will happen in the real world. 2) The Friction/ Bound parameter is not right and should modify

Or, we should not take too much time on the final landing process on heliport, and this part should be achieved by operating experiments in the real world.

@iKrishneel Please check the process. If you think it is OK, let us integrate your visual tracking

for simulation, I agree your comment, you can update track plugin so that once drone reach to the heliport, we can attach(ignore bumping, stop update motion....) the drone to the traack

In addition to that, we'd better to check real robot's behavior? using

normal car or bicycle or cart.
