Day 01
With only an afternoon to work with on the today we decided just to sit down and brainstorm what we would do rather than just rushing in. I thought this was a good idea as we would start with a solid base to work with. We broke up and made our way home to some research
Day 02
Today we decided that we would use an ink based art form. We will have a trolley which moved along tracks to distribute ink in a line. The movement would be constant and the amount of ink dropped would be determined by a catch that moved back and forth across the end of the dispenser in relation to the sound level. This seemed like the easiest way to distribute ink as we will only need to program a linear relationship between sound levels and catch movement to make it work. At the end of the day we started to build the frame and got a basic rig that could move forward at a constant rate. Over the weekend I will work on the program and see if I can get it working as none of us were able to do it during the day.
Day 03
After the weekend I was unable to program the linear relationship. We quickly changed the programming as this was an integral part of our system. By changing the programming to move to the beat of the music and drip at a constant rate we could still make a robot that would make a pattern based on music. Today we also had to decide on a medium and we did some research and came up with the idea of using water. We did some tests to check what the ink would do when it hit the water. These produced very interesting results that would create a unique image.
We worked well today and got all the final ideas set in place as well as building a simple track and reprogramming the system.
Day 04
We decided today to make a new set of tracks that would better support our robot. With the help of the 3D Lab technicians we were able to build a frame from a few piece of steel bar. No skill was required as we only had to bend the ends to 90° and then spot weld them in place. The previous night we had also collected a few bottles to use as the dispenser and we decided we could use a Ch’I bottle for this purpose. We did a dry run of the dispenser using water colour paint and paper. The results came out very pleasing
When I got home I found out from a family member about marbling inks. These are slightly insoluble in water and would be perfect for our project.
Day 05
With the addition of water to the project we had to make a suitable container to hold the amount of water we would require to make a good image. We once again went up to the 3D Lab and with the help of the technicians built a box. Last night I had driven in with a sheet of glass to use for the side of the box so that we could get clear images of our robot in action. After measuring and cutting the pieces we nailed and screwed it together and then preceded to water proof it with silicon. Once this was complete we decided to test it but found when we did this it had 2 leaks. We decided to leave fixing this till tomorrow so it could dry.
With the addition of the marbled ink our range of colours also increased and we decided to try to incorporate all of them at once into the final images. We made a new dispenser out of the original Ch’I bottle that would house all6 of the marbling ink canisters. This would let us use the inks own canisters as the dispensers.
After we constructed this we added an extra motor that would rotate the dispenser so the colours would fall in different areas each time.
At the end of the day we all felt confident that we would get this finished tomorrow
Day 06
When we arrived this morning we were all in high spirits.
We finished patching the box and got ready to start the first test. When we ran the program we were a little surprised to find that we couldn’t get that ink to drop.
We had assumed the motion of the robot moving back and forth would be enough to cause the drops to fall. After this was discovered we were a little stumped with what to do. We tried pricking a small hole in the back of the bottles to allow air flow and to break the vacuum. This was partially effective as it allowed ink to flow but could accidently cause it to flow to fast releasing all the ink in too short a period of time. After this we talked to some of the year 2’s and they suggested changing the rig so that it flicked the ink. The back and forth motion created would create enough G force to make the ink drop. We chose to change to this method and it turned out to work ok. The rig was simple enough to change as we only had to switch the motor into a vertical position.
Now that we had a working robot we could record the final outcomes. We recorded one using all the marbling ink. Although it took a long time to run the outcome was very interesting and we were able to get some good pictures.
We did our 2nd in a dark room with glow in the dark ink. I found these images to be even more interesting and strange.
We decided on these images as our final pictures.
