Team Status Report for 02/27/21

We worked on the project proposal and finalizing our mechanical design this week. We decided to not use the rotating plate for placing the fruit anymore as it would not support non-round fruits, like bananas, very well. We, instead, are planning to use a diagonally placed 2-camera system to take pictures of the fruit. We have also decided to use pistons to push the fruit in the right direction to physically sort it.

We researched pistons, specifically solenoid-type pistons, on Prof. Savvides’s suggestion, but we found them to be quite expensive. We are a little worried about using pistons as none of us have much of a mechanical background so we will discuss our mechanical design again tomorrow.

As of now, we are slightly behind schedule as we had wanted to order the parts this week but we think it is better to talk and share our parts list and reasonings to the professor and our TA on Monday before buying things. So, this is not too concerning as it is better to double-check before spending too much money. Ishita Sinha and Ishita Kumar have started looking at color analysis and image segmentation and should code up a simple working sample by next week. Kush will meanwhile take pictures for training data. If we get all this done next week, we will be very well on track.

Ishita Kumar’s Status Report for 02/27/21

This week I helped my team prepare for the project presentation. I researched papers on automatic rotten/fresh fruit sorting to propose better ideas for our mechanical design. We decided to get rid of the rotating plate idea for now due to it not working well with non-round fruits such as a banana. We plan to go for a diagonally placed 2-camera system.

I also researched pistons and in particular, solenoid-type pistons due to Prof. Savvides’s suggestion. They were more expensive than expected, ranging from $245 to $436. I also have started looking up code samples for image segmentation and plan to implement a simple one in the first half of next week. I think we may be slightly behind schedule but not too shabby. The mechanical design, particularly the pistons worry me. So, I plan to meet with the team to go over our design again.

 

Ishita Kumar’s Status Report for 02/20/21

This week, in our initial meeting with Prof. Savvides and our TA Uzair, we were recommended to implement FarmFresh MVP with bananas as they rot quite quickly and noticeably. Since our FarmFresh design as of now plans to use a rotating plate for fruits to be placed on, I researched ways to hold up a banana. I found a banana holder that could fit our needs in the market, but we may have to design a transparent or thinner version of this. Alternatively, there are hammocks or hangers for bananas that can also hold a single banana. For now, we plan to just manually take top-view pictures but different angles will be important later on.  We are on schedule as of now. For next week, I plan to research ML models, that will work well with recognizing fruits. Specifically, I will look into Image Segmentation and try to implement a simple program that can detect bananas in Google images of them.
