It's so brilliantly simple yet very effective. Who needs whirling lasers and cameras photographing the ceiling?!!
I noticed those and was wondering what they were used for!! I didn't see anything below them, so I didn't suspect. Quite clever to detect a bump. That's why when it hit the tennis ball trying to dock, it barely moved. At first, I thought it would:
1) push the ball into the dock;
2) push the ball harder and then back up.
Here is the picture with the magnets circled in red:
