Robotic arm not moving in motion planning

edit

Hi guys so i was working on a project to move a robotic arm using rviz, first i made the design on solidworks, used SW2URDF to get the URDF file, the URDF code is too long to post here but basically i checked that the joint limits are correct first i launched the display.launch file into rviz, played with it a little using the joint state sliders and it was moving fine i wanted to move on to motion planning so i ran the file through MoveIt setup assistant following this tutorial http://docs.ros.org/kinetic/api/movei... then i launched the demo.launch through rviz, made sure i am using my robot base as fixed frame the problem is that the robot isn't moving with the interactive markers like the panda robot in the tutorial did i can't move the robot at all, so i can't perform motion planning i tried to bypass that by generating random goal and start states in the planning tab but ofc the planing failed

i also noticed these 2 warnings in the command line:

[ WARN] [1549150437.741202943]: Interactive marker 'EE:goal_Gripper' contains unnormalized quaternions. This warning will only be output once but may be true for others; enable DEBUG messages for ros.rviz.quaternions to see more details.

[ WARN] [1549150436.699550818]: The root link base_link has an inertia specified in the URDF, but KDL does not support a root link with an inertia.  As a workaround, you can add an extra dummy link to your URDF.

can anyone guide me to what might be the issue here?.. thanks in advance
