Hey LMR citizenz! Am currently working the geometry bot. Only thing it can do is go in squares. And with a change in resistor i starts moving in triangles or any polygon with equal sides. It does not work on any microcontrollers. It uses 2 555 timers and a L293d to drive the motors according to the output. The circuit works as planned but I am not able to find proper wheels for the motors. All types of caps i tried just used to slip off. Can any one name a few sites i would be able to get wheels ...
