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.
