So we have been making slow but steady progress with our inspection system. Since this marks our completion of ten blog posts, we decided to do a brief review of what we have accomplished so far and all that is left to be done. We set out with the intention of improving the current state of the art in industrial inspection systems, but as we moved forward, we found it better to focus more specifically towards catering to the oil and gas industry. This was spurred on by positive interest from som ...
  GraffitiBot is a fully autonomous ground vehicle capable of printing graphics on the surface it is traversing. This crude attempt artistic rendering at writing "E14" demonstrates what the GraffitiBot accomplished on the last day. Update The challenge has ended, but I did not stop experimenting with the GraffitiBot. As shown above, the bot spays too much fluid and drips where it shouldn't. I had ordered some syringe dispenser needles to achieve more precise nozzle flow, but they did no ...
Well - it is the last day of this marathon design challenge and everything pretty much needs to go flawlessly to produce actual graffiti. But of course a lot of things are not going right. All the subsystems have been tested and are working well, but the bot is just making puddles. I thought the nozzles would be problematic, but the main drive is not running properly, so put on the troubleshooting hat and dive in. It looked like the batteries were dying, so take some time and charge them up. Sti ...
