A fishing rod that can fly or hover over the water to grab a fish. Once the weight is increased on string it automatically rolls back and put it into a box attached behind it .
If we want to use semi-automated fishing rod.
We can just disable automated rolling of string and control it by using remote control.
We can install camera mounted on the fishing rod so that we can see what is happening beneath or above the water.
Then fishing would get interesting by controlling fishing rod with remote controller.
