Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Help with next step IK industrial robot


I have managed to create a BP with an industrial robot that moves with w, a, s, d, turns, swing rotate etc.(base mesh is targeted with key w, top mesh with mouse etc) That is fine but my next goal is to have the robot turn to a point that i choose. I want the grey tip to be the center of my movement control and as i move the hole arm twist and moves automatically in the correct place. The robot is fixed to the ground. Shall I use skeleton mesh or perhaps physic component constraint? I´m not sure what go for next.

But I don´t know where to begin. I have all the pivot in correct places and bone hierarchy should be fine.

Can some one please give me a hint where i should start.

In the long run ( maybe months :) to get there) i would like to have a robot with AI that can pick up things placed randomly in front of the robot.

Regards Steel

I would use skeletal mesh. to position the arm to pick things up that are in reach, it is best to break it into small steps.

  1. Determine which objects are within reach.

  2. Choose one to pick up.

  3. Rotate the arm to face toward it.

  4. Once the arm is facing laterally toward the object, you might use IK to retract the arm and pitch it down so that both the rotation and length are correct to land the tip on the object. that will be tge tricky part but I think IK is a good approach.

Thanks for your input.

I think i have manged to set up the constraint in the correct way. When it falls it falls correctly. What is the next step to get it to move? Just to see if it moves that it should i would like to steer the grey cylinder with mouse control and see it turn and twist as intended.

What is the best set up for this?

Regards Steel
