Its an area of active development and research - https://youtu.be/5chk9Sory88

Note that this is an area that is rather specialized - a pepper picking robot isn't good for tomato picking or lettuce picking ( https://youtu.be/EFC3OvkVKaQ ). Compare that to the incredibly versatile human ( https://youtu.be/oxbJVqfIK1U ).

I think it's possible the whole system could be automated. The problem really ends up being one of cost.

It's similar to the "burger flipper robot" problem. Possibility solvable, but also gonna be costly and buggy for v1 of the robot.
