I've always wondered... Why aren't pantographs used more with robots when precision is needed? It's used to cut precise wood pieces or carve wood or metal etc.

You use the "big" part to drive the "small" one, which gives it great precision.
- abecedarius 2y agoFeynman brings up some problems with pantographs and precision in https://calteches.library.caltech.edu/1976/1/1960Bottom.pdf https://calteches.library.caltech.edu/1976/1/1960Bottom.pdf (page 6-7). I haven't thought about it myself, though.
- whamlastxmas 2y agoPantographs are mostly useful in 2 dimensions and any robot only needing two dimensions can just use rails which will be more accurate
