Motion Plan Fail & All Supplied grasps failed #4
Comments
I am also seeing this with the pick and place demo and the latest clam code from indigo-devel. At first I was getting an error in the moveit core libs but fixed that by using the latest moveit code from source in my clam workspace. I am running the demo like this:
and am getting this output in the move_group terminal after a failed pick attempt - usually it is this:
but once it was this:
I am also attached a screenshot of the rviz visualization - any ideas on how to debug? |
OK I have made a bit of progress. I moved the block locations a little in moveit_blocks.h in moveit_simple_grasps package and then it was able to find the block and tried to plan a path but there was an error in the controller code : From the pick and place terminal:
From the move_group terminal:
From the lowlevel_simulator terminal:
So getting closer! I will trouble-shoot this later today - any advice welcome :) |
The latest error "Unable to locate joint elbow_pitch_joint" seems to be because MoveIt is sending a Trajectory message with only the gripper_roll_joint specified and the dynamixel_simulator_interface joint_trajectory_action_controller.cpp file seems to be expecting all the Trajectory messages to have all the joints specified. |
Dear Dylan Many thanks. |
Dave, hydro code compiles great.

Would this be related to the collision between Block1 and the l_gripper_finger_link or could it be related to approximate kinematics as mentioned in: https://groups.google.com/forum/#!searchin/moveit-users/no$20motion$20plan$20found/moveit-users/cup7Z-1bug0/ivp9a2ZNsZcJ ?
There is a very similar problem mentioned in the moveit group (https://groups.google.com/forum/#!searchin/moveit-users/no$20motion$20plan$20found/moveit-users/_M0mf-R7AvI/cV4v755bwEQJ) but I have not yet figured it out.
