+- Include the local implementation of joint controller and joint trajectory execution (gazbo implementation) in these packages.
+
+# Possible future contributions
+
+gazebo:
+    - the higher-level controller with position and velocity
+    - a program which helps find PID values, either with neural network or Ziegler-Nichols method
+
+# Objects
+
+- move away from object_msgs and replace with object_recognition_msgs/RecognizedObject.msg. The bounding_mesh
+can be used to replace primitives, which then have to be supported in object_moveit/ObjectMessageGenerator.
