Nothing on MovIt, but the following recent article in Servo Magazine provides a cookbook for building a ROS based system that addresses several of the features you mention (at least conceptually), out of a Roomba and an Xbox Kinect for vision.  I appreciate examples like this that steps one t

Asfor communicating between computers, you will find that one of RS' main purposes is to move data between nodes that might be (or not be) on different computers. you can even move the nodes around at run time. Just about everything in your proposed system would end up being a ROS node,even the u

Chris, many thanks for the reply. I am indeed planning on using computer vision to set targets for the robot arm to move to. Thanks for sharing the link to MoveIt. One solution could be to have my computer vision code send the waypoints I want to MoveIt, which would plan the path, and then send th

What LCNC lacks is high-level motion planning. LCNC's version of motion planning is means planing the speed of all the axis and keeping them coordinated so that the end effector(cutting tool) traces the specified path. What LCNC does not do is design the path. For example if the dripper is hold

If you are taking the right approach or not depends on the tasks you want this robot arm to reform. Are they entirely scripted such that you can write G-code to control the arm? Or is this arm using a camera and vision system to pick up randomly placed objects? If the former, LCNC will work fin
