Sixth Sense GarffitiBot - First Dry Run - Blog17

This is a big day - the GraffitiBot made its maiden voyage!

This was just the first attempt at programming an autonomous route that would test the steering and the main drive.

It is literally a dry run, there are no pumps or even reservoir on board.

I could spend some time to make it look more impressive and get some better camera angles, but I need to start working on the hydraulics - the nozzles need a lot of work, not to mention the software.

Getting this far has taken a lot of work, but see it run is what is all about.

    Looking good! Seems like steering and drive are stable and responsive. Good luck as you tackle the hydraulics. Gene

    You seem to have everything well under control. Good luck with the next stage of the project. Kind regards.

    That is really nimble and fast. It's a good job Graffitibot didn't have the paint mechanism set up - your nice floor would have got a bit messy image

    I am still negotiating the rights to mess up the floor ..... image

    It goes like this ... is it okay to get the floor wet? - image NO

    How about damp - is it okay if it is just a "little" damp? - image (silence)

    What if it is just a quick damp and immediately dried off? - image

     

    Some projects have hidden "costs" ... image
