STEM Education Robot using Pencil and Paper

My idea is to design a robot or electronic-based educational kit that can be programmed with paper and pen: we have a pre-defined paper tape, and multiple combinable mechanisms/modules such as sensors, motors, etc. that allow for a myriad of combinations. Users can write their programs by blacking out/writing numbers on the paper tape as prompted, without the need for a computer and phone to program. The controller scans the programmed paper tape line by line, executes the corresponding program, and provides timely feedback on the results of the program run.
