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"

How to convert axes from arduino to relatives and lift knee/move legs up/down


Can someone help me, guys? I am using UE4Duino plugin to receive X-axes and Z-axes from Arduino using serial port successfully. However, I have hard times by trying to convert values to relative axes in UE4 and also control person legs moving up and down (lifting knees etc). You can see the blueprint screenshot attached.

Please advise!!!

assuming that the value you currently have is in world space then all you need is the inverse transform node to convert world space to local.

Thanks for the prompt reply!

The problem is that I want to move knee up/down, lift the knee and then bring down the knee. Getting sine and cosine from Arduino. It's not geolocation, altitude or something else.

Maybe I need [Animation Rigging Toolset][1] from Maya? To build skeleton on robot and control legs ending etc?

Please advice.
