Plastic that didn't cut thru

Wooden track

Reflective statement

We watched a video which is a women draw something on sand with music. Than Eddie said we could do something similar with ink and water. We were supposed want to use strings or ropes tie above the tank. But our robot was like move, shake and almost drop into water. Than we found cog has bigger friction. However it still slippery on the string. It's good to have a track idea coming. It took us whole day to test different martial which contained two pieces of plastic. But none of them had been cut through. At the last we found a piece of wood. The risk of use this was flame caused by the laser. Luckily it still work fine. Another problem was how to drop the ink. We were thinking about make a dropper to squeeze it out, but squeezer was to hard to make and drop too much ink at once which will pollute water entirely. Instead we got rid of those thing only drop ink by gravity. The weak point was it drops randomly sometimes will lose control. Lastly in terms of drawing a picture, so we add a arm which going to push the remote of the camera by its own that make a sequence of image that illustrate how inks dissolved in the water.

Monday
We generated a few ideas which involved water pump, sand man, spider man holding pen, and decided what we gonna bring the next day.
Tuesday
Eddie brought 2 water tanks and several fish soy sauce dropper, Brandon brought fish strings,Robert brought a wooden square and food color which got blue black red and green. We tested robot on strings. But it was not strong enough to support the robot. Afterward we combined different colors in to water see which two work well.
Wednesday
James came n told us about the laser cutter. We took the whole day to make our track. Initially laser cannot cut through the plastic. We found another wood board instead. Brandon and me went to the laser cutter room. The guy said" the wood board won't work because the track is so fine to cut by laser. Between each slot only have 1mm distance. The wood will get crunchy." The process was scary. we just stand there n see the wood were burning by the blame. Fortunately, the flame was sucked away. Finally the product was all black. But still smells good. As long as we return, our people got out from the building because of fire alarm. Brandon said" the others gonna say, yeah! we can go home. but we could go home anyway if you want."
Thursday
Finally test on our track with ink squeezer. Just fix a bit program problem. We done!
