I am attempting to design a component to remotely control the throttle on a mini petrol powered ATV as a little project. Initially I have had the idea to adapt a standard cruise control unit to do the job but was wondering if anyone had any other suitable ideas? (Obviously this will not go out on the roads purely for uses on my private land) but ultimately I would like to remotely operate the brakes, throttle and steering. Also what would be the best way of testing the forces needed to operate or turn the butterfly valve? Obviously it is connected to a spring so that it the butterfly valve always closes when your foot comes of the accelerator. I have attached a picture of the throttle cable and where it is attached to the carburettor.
