This week I worked on both the mechanic and software portion. On the mechanic side, I helped Vasudha with constructing the swinging door, we discovered that attaching the servos with the wood first may not have been the best idea, since the legs are curved in and we probably have to redo it when we attach the shaft.I think we should work with the lid and the bin directly instead of working with the legs for now. The platform itself seems too heavy, we are thinking of switching to plywood. Also the clamps we ordered were too big and we have to order smaller ones for the shaft to fit better. Schedule wise we probably have to figure out the swinging mechanism by the end of this week to be comfortable.
On the software side, I trained a trash dataset on top of our original model. Our class names were different for the same object for some of them, so the model was finding minute differences that it wasn’t supposed to learn. To fix this, Aichen wrote a script to change classes into 4 classes: trash class, 3 recyclable classes. Using this script, I retrained the trash dataset on top of our original model. We are testing this now, and currently it’s having trouble classifying recyclables as the right class. We will have to look into this after final presentations.
