The machine ready to get a can.

The machine opening a Kal Kan can.

The automatic dog feeder was one of Emmett Brown's inventions that he built to feed his dog Einstein in his garage. He would put cans of Kal Kan dog food on it and then it would dump the food into Einstein's bowl. When Marty returned to Doc's garage in 1986, as stuff at Doc's garage were being sold, he turned it on, but there were no cans in the gripper arm.
