I need help writing a function with one input and one output

Im trying to write a function 'walk'. My input is 'number_of_steps' and my output is 'steps_made_successfully'. Im trying to instruct my robot to take a 'number_of_steps' and it return how many 'steps_made_successfully' before the robot would run into a wall. This is what I have so far but I dont know what I'm doing.

The syntax for defining a function is:

function steps_made_sucessfully = walk(commanded_steps)
% insert your code here
% ...
    steps_made_sucessfully = ..  % make sure that the output parameter is always defined
end
