This was a test of making the iBot move through a 30x30 square. When it reached the end of it's path it was off by about 1cm. The line is just to show where it ends up.
Note that this rover uses some VERY dodgy stepper motors, and uses completely open-loop movement - no line tracking sensors, no other way of telling how far you've moved. The only way to work out how far you're moved is to work out how far the rover moves with each step of the stepper motors.
The rover is used in a University of Adelaide subject called "Project Management for Electronic Engineering", and we (my group) were tasked with building part of the iBot, and programming it to move to a set of coordinates inputted via the buttons below the LED displays. One of the challenges is working out the relationship between real-world distances and steps of the stepper motors, and this video was taken partway through testing.
