- After pivoting our design for the motor and eraser system, we expect a better performance for the screw motor because the movement mechanics is no longer significantly affected by the weight and friction exerted on the wheel. And as we start to work on the RPi and camera part, we notice some potential risks about the camera. It is an IP camera that can work under the same WIFI as the web app, and at current stage we are only able to obtain the JPEG format of the image captured through the camera by setting the camera and our laptop at the same WIFI (we have not deployed yet). Since we potentially won’t guarantee that things work the same once we deploy the web app, we see there’s some risk that could jeopardize the success of image capturing. To solve this issue, we investigated how the IP camera works and noticed the image is uploaded to the website provided by the company that sells the camera. We could look for potential APIs from the website or look into downloading the images from the website if our webapp cannot exist in the same WIFI environment with the camera.
- This week, we are working on writing code and exploring how to control camera and motor, etc. There is no major change in the design of the system. One change we are expecting would be that we want to add some protect around the screw rod and motor after our Ethics discussion because we feel the need to lower the safety concern as much as possible.
- Schedule change: we’ve moved camera to this week since it is part of the webapp backend code. Due to this change, we’re postponing the usability test for other webapp features.
