Hi all,

I'm going to design a ball launcher machine, but i've no idea where to start from..
this is the ball type: http://en.wikipedia.org/wiki/Sepak_Takraw

how do i judge the power and rpm required for the motor??
as i know, there is a initial velocity required for the roller, so the ball could achieve certain distance.


please enlighten me, thank you vey much =)

for this tennis ball launcher, the power required for the motor is 154W
http://www.ece.uvic.ca/~dwolowic/MechProgress.pdf [Broken]

so perhaps it has to be slightly higher than that, since the size and weight is bigger..

Probably the best place to start is to carefully read the report that you already have in hand that details a similar design problem. It gives you quite a lot of information, and it describes a lot of possibilities. Ultimately you will have to go through a similar process for your problem, and your results will probably not be identical to what is in that report. Never the less, it is an excellent place to start.

I don't think you need help nearly as much as you need motivation to start. You have a very good report that lays it all out for you.

If you really need to study projectile motion, this topic is described in countless mechanics texts (dynamics).
