Sweeper - Final day

Working fast, working smart and working quick we managed to rebuild the robot completely from scratch into an entirely new model. We had not one.. But two ultrasonic sensors in the front to respond the both of the brains. And this time round we even had a sound sensor to control the speed that the sweepers moved back and forth at. However this time around the sweepers were now moved from the front to the sides. And the design?.. Nice and simple and not complicated at all or heavy. And really for the first time we were pleased and happy with the result we came out with.Now came time to finally create a base for our robot to create it's artwork in. Short on time and materials we poked around to find remaining roof boards and pieces, with permission of course. We hand crafted the base with cardboard, roof boards and metallic rods for support in order to come out with a little home for our robot to play in.


So with a robot that not only had proper working sound and ultrasonic sensors the motors all functioned appropriately with every cog and gear down to the last detail but, even a base for the robot to play in and, with smiles on and faces and relief from the anxiety of time we moved quick to try it out.

It was finally time to test out the true effectiveness of Raro and water. For this experiment we worked around to find a way to use the brush bristles. Ripping apart the bristles from the brush we tied a bundle of bristles together with a rubber band. We filled both of the small jars with water reasonably close to the top and stuffed each bottle with a bundle of bristles. This allowed water to seep through the tiny holes. And attaching it onto NXT pieces on the front with a rubber band it dabbed at the paper to complete one of the designated art pieces as we started with randomly places Raro on A2 paper.
Now to move onto our second test. Paint. We filled the small bottles each with a reasonable mix of water and paint to make it nice and slushy for the paint to seep through. This time, using cotton pads we taped the tops of the bottle with a thin layer of it that allowed the paint to seep through on each dab. And we taped the sweepers with cotton pads as well while allowing the pads to soak up paint before starting the experiment. With a new sheet of A2 paper we let it go in its' own little base again dabbing at the paper with dabbers and sweepers. The end result proved positive but one thing that became noticeable was that the orange dominated the recessive yellow color. We chose these colors to represent the night life which was our main idea for this project however, due to the fact the yellow wasn't mixed as well as the orange nor was the bottle as full the yellow did not come out as well as it could of.
Last but not least came the light graffiti. Attaching on the three LED lights with blue tack we had one light on each side of the main brain box. And one light in the front between the two ultrasonic sensors to act as a guide in the dark helping the robot recognize objects. This proved to be the most successful with the most vibrant and powerful result. Using shutter speed and time we managed to absorb 30 seconds of light in the dark room as the robot roamed about without hitting a single wall.

All in all we came out of the day managing to not only finish our robot of many trials and errors but all three artworks ready for our demonstration the next day.
