June, 1st-8th = 2d Design, Assembly, Tests
June, 8th-15th = 3d model and 3d print spring gears, test gears, test ultrasonic sensors
June, 15th-22th = tests, starting construct algoritm with GH and LadyBug
June, 22th-29th = Tests and documentation
1. WHAT IS THE DEADLINE? HOW MUCH TIME DO I HAVE LEFT?
Deadline will be on June, the 28th. I have not so much time to make my final project exactly I was imaging. Anyway I succeed to reach a good point.
2. WHAT TASKS HAVE BEEN COMPLETED AND WHAT TASKS REMAIN?
I have succeeded to produce the machine and the shading system. I have faced a lot of problems regarding the friction of the rotating gears, but I figured out the issue. I still need to create the algorithm and elcetronics and make everything moving smoothly.
3. HOW WILL I COMPLETE THE REMAINING TASKS IN TIME?
I will try to not be perfectionist. I will work in order to obtain a competed and working machine, then, if i will have time, I will improve some parts.
4. WHAT HAS WORKED, WHAT HASN'T?
Almost everything, but I needed a lot of time to correct everypart. For example I had to sand 3d printed gears to get the lowest friction possible and do a lot of tests to understand the behaviour of the machine.
5. WHAT QUESTIONS STILL NEED TO BE RESOLVED?
Programming! I understood that it is not so easy to get sunrays vectors and, depending on location, obtains a certain value of rotation. Moreover, all 3 Hc-Sr04 generate 3 different variable that interrupt the sun-following behaviour and create a new arrangment of the machine. I still have to study correctly that. I am starting to work on some simulation in Grasshopper.
6. WHAT HAVE YOU LEARNED?
So many things. Beyond digital fabrication, I understood that a good correct time plan is crucial. I also learned that unexpected issues are to be taken in consideration everytime.
