Perhaps you should try some spelling variations:
"coder implementation and robot programming" » "code implementation and robot programming" (Expand search), "decoder implementation and robot programming" (Expand search), "model implementation and robot programming" (Expand search), "coder implementation of robot programming" (Expand search), "coder implementation and robots programming" (Expand search), "coder implementation and goal programming" (Expand search), "coder implementation and cone programming" (Expand search), "coder implementation and robotic programming" (Expand search), "coder implementation and robust programming" (Expand search)
"python using pid python programming" » "python usando pid python programming" (Expand search), "python coding pid python programming" (Expand search), "action using pid python programming" (Expand search), "python using in python programming" (Expand search), "python using via python programming" (Expand search), "python using api python programming" (Expand search), "python using rapid python programming" (Expand search), "python using lipid python programming" (Expand search), "python tuning pid python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder implementation and robot programming\") OR (\"python using pid python programming\"))~".
• Removing quotes may allow a broader search: (( coder implementation and robot programming ) OR ( python using pid python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder implementation and robot programming") OR ("python using pid python programming"))*.
