These are definitely not the responses of someone you'd hold in high esteem, so what makes you think we are going to listen to the petulant unfounded ramblings of an emotional child?

I'm building a robot and I've run into a dead end with regards to sensors/guidance. Any ideas/semi-productive shitposting would be useful.

I am designing a robot that needs to be able to drive from a starting point to another point in a *perfectly straight* line for 100m (330 ft). For simplicity's sake let's define that as <1 cm error. What is the cheapest way to do this?

If necessary you can mount equipment on a pole at the destination point. But keep in mind that some robots could have dozens of separate locations that they have to perform this "straight line task" at. So emphasis on the cheap.
Also, feel free to include a one-time calibration phase to acquaint the robot with it's environment(s).


List of rejected ideas will follow in the second post (for those so interested).
