In the beginning I tried to position the disc precisely over the tray using an overhead webcam and opencv. This was not reliable enough because the robot arm is stit so I just used brute force. It turned out that a few attempts to open and close the tray get the cd in place every time 😉. The only failure mode right now happens when the tray pushes the CD on the top of the drive and closes correctly. But this error can be easily detected.
