Mult-sensor line follower

#1

I am thinking of adding on to my mBot kit to build a line maze solving robot with three line sensors with my son. The three sensors would be attached to the front of the robot using one of the bracket kits. The idea is to use the three sensors to identify the intersections in the maze.

It will traverse the maze in a set sequence and record the intersections as it learns, then solve the maze on a second run

Any comments or suggestions on whether this should be doable with an mBot? Trying to get some advice before spending the money on sensors and brackets.

I’ve posted an idea for a dedicated maze solving line sensor to the New Product Ideas forum (link). I built a maze using 3D printed posts and foam core board for my students (see link). This version, done in Scratch (mBlock) uses a left-hand wall following approach. The next class I’m teaching will be doing the same thing in C/C++ (Arduino) where we can explore more complicated algorithms. I’ve found that Scratch is pretty limited for doing anything complex.

With regard to using additional line following sensors, I believe that you could certainly do what you are proposing with a few brackets.

yes! the mBot can do that !
