So our team has an idea of making a crossbow luancher to launch the balls. We're thinking of using metal springs to luanch the ball and to pull the strings back we are using a motor that will pull the ball back then will attach to a hook that we can then release for luanching. Will this even give us a good distance and has anyone else tried this.
it wont neccesarily have limbs, we're looking at attaching the springs to a frame that will be connected to the ramp the ball goes down something with a board underneath that will connect the ramp and the frame and we will load the balls through the front with a conveyor belt that loads to the ramp and then a motor will pull back the springs and then WHHOOOOOOOSH.
My advice is anytime your intuition tells you something, double check it with physics. - tennispro9911 [more]
