Mechanism of throwing a shuttle with the help of string attached to it

akashm.m
akashm.m over 8 years ago

Please suggest me the mechanism of throwing a shuttle having string with the help of bot.

I want the mechanism of rotating the arm of bot

& The timing of releasing the shuttle.

    Hello Akash,

     

    I can suggest something I have experimented almost in depth and it worked with very good results on Arduino board(s). A cheap weight sensor. You can see this post to have an idea on how it works. Then if you agree with this solution I can help you further. Let me know.

    Now things are more clear. I think that despite the kind of motorisation you plan to use you should consider to study the math of vectors. There are two vectors; one is the rotational (non Euclideal) and the other is linear. The target is the result of the 3D sum of the two vectors. Then you should transform them in the angular Pi-ro for every motor and then convert this motion - supposing to use stepper motors that in my opinion is easier to manage - in steps and eventually microsteps to reach more precisely the axial values.
