This week, we got the bigger servo as the machine shop suggested. And we talked to them again, and our mechanical structure should be coming out soon.
Also, the camera part is working. It operates on Raspberry pi which is connected to a local Ethernet. We can use an online platform called Weaved.com to share the desktop of the Raspberry pi with any phone or PC. This way, we can view the live video from the camera. It is not smooth, though. We will try to figure that out. And also the audio part. But the camera and speaker are separate from the rest of the feeder, and the actual feeding part of the project is performing everything we intended. We just need to adjust some parameters of the code when the actual mechanical design comes out.
