tera_iiwa_ros_ext

TO DO:

~~Do check on the robot with out any end-effector ! ~~

steps:

- Do only with the manipulability !

- Do check the value of wrench uncertainity.

  • Do with the full opti function

~~- record rosbag for ext torques ~~

  • compute covariance matrix !

  • re-implement and check !

Tried to check tau_cmd - tau_ext --- Nothing found coz both are equal and opposite in every condition.

Just check how much torque is off !

Done and Working:

force_estimator node working, : 
    Computes Wrenches wrt base ! using RBDyn library (for jacobian) and using commanded torques (simulation)

Cubic_p2p.py Node working: Verified in Gazebo! 
    Computes cubic trajectory (q(t)) for the PositionController mode of the robot. 

trapezoidal_p2p.py:
    Computed trapezoidal trajectory. CURRENTLY COMPUTING WRONG! 
    
Moveit_joint_position.py:
    Moveit needs to launch that uses PositionTrajectoryController mode. This node is also initiated using a launch file, that should be defined in the launch folder. (Launch after moveit launch!)

Changes:

optimize_test_no_file_sim/real :   there is a change in `cartesian_damping_factors` and `cartesian_damping` between real and sim. 
similarly: for nullspace
