I would like to build a simple robot for an art project. The robot basically needs to be able to move in 4 directions (e.g. north, south, east, west) and needs to be relatively precise (maybe ±1mm). The actions can be pre-programmed if that makes it easier.
I have seen some of the kits in the FAQ section, but they seem quite expensive and over complicated for the kind of thing I’m trying to do. Would there be a simpler way of achieving this? I have a physics degree and some knowledge of coding.
Thank you in advance
