I want to control my ornithopter in such a way that I press keys on th
keyboard, and the signal is transmitted from the transmitter, which i
received by the receiver, resulting in bird motion. Is that possibl

I don't know of any off-the-shelf solutions to your question.
There is no reason in principle why you can't rig a TX
to be driven by output from a computer.
The devil is in the details. I've never succeeded in creating
my own control circuits, even though I think I know the theory.
A friend who really does know what he is doing with
circuits used to fly drones via portable computers
back in the Vietnam war. It was in the pre-PC days.
If they could do it then, you could do it now.
And, of course, lots of current drones are controlled
from the ground by computers ...
Having said that, there are easier ways to get RC
Sometimes, just knowing that something can be done is enough to provide
sufficient impetus for serious work on a project.
I'm guessing, but I suspect that the OP (original poster) is seeking a
vehicle that is capable of hovering as well as forward flight. The reason I
say this is that other than for novelty, there would be no other reason that
I can imagine for wanting an ornithopter, other than novelty.
If one wished to start from ground zero in developing flight software to
control all of the actuators in said ornithopter, might it not be easier to
do on a laptop than to worry about making the bird autonomous with its own
Unfortunately, the delay through the system would be problematic, if that
was his goal.
Computers are very fast, it's all that software that slows them down. If it
was programed in binary it would be faster than I am. Do they even program
in binary anymore?

Compilers are supposed to take care of that menial task. The problem
is now more related to the relative slowness of the interface. When
it comes to controlling an RC tank or car, the speed is far less
critical than trying to control a flying object where split second
timing mistakes can me a crash. Even USB 2 is slow enough to cause
serious delays in control. Remember the early digital proportional
systems and how much delay there was between stick and stab?
There used to be a web cam setup where you controlled an RC equipped
Tonka Toy dirt scoop. It was great fun but almost like using a
Martian rover from earth. The delays were phenomenal. I'm sure you
could rummage around and find other remote control items like it.
