Line follower sensor experiments

IMG_3237 The simplest arrangement for a line follower is probably two sensors with digital outputs. As long as one can see the line and the other can see the background, the controller is happy otherwise it must turn left or right as appropriate. I was after something a bit more sophisticated for Bob the Line follower…

New line follower robot

Img_3222a Line followers are a perennial favourite of the small robot builder. It is not hard to make something that will bumble about and follow a line marked out on the floor. the technology can be very simple but the same basic idea is used in sophisticated robots on factory floors. The tricky part is in making the line-follower fast and smooth in its response. Whether or not I can do that remains to be seen but I am going to have a go …

Winmaze – Another Maze Editor

It seems that all micromouse builders get around to writing their own software for displaying and editing mazes in the end. This is mine. It is a Windows only application but should run on pretty well any version of Windows. I have not tested it on Vista. It can open maze files of several types including the ‘standard’ binary mazes and some types of text maze. Changes to a maze will always be saved as a binary maze file. (note: revision now will not ask for libraries)

I was quite excited about having a real debugger to use. – especially as programming the STM32 through the bootloader is a bit of a fiddle. Things didn’t turn out quite as I had hoped…
