What Im trying to accomplish is high speed linear motion using a 360 deg hacked servo, driven with conventional PWS servo control. Will this do what I'm hoping it will?
Hi,Quote from: Bart_at_Haunted_High on November 11, 2011, 07:34:11 PMWhat Im trying to accomplish is high speed linear motion using a 360 deg hacked servo, driven with conventional PWS servo control. Will this do what I'm hoping it will?Depends on how you define "high speed", but I wouldn't use that description in relation to servos, as they're typically around 60RPM give or take. With "PWS", I assume you mean PDM a.k.a. a standard hobby servo signal?Why not stick to your first thread and give us the numbers we need to help you?
Thats just it..I dont have any numbers.Except that the linear length I need is about the full length of a guitar neck. so for arguement lets say 18 inches.As for speed, how qyickly does one change frets from one to another when they're playing power chords in a rock song.? A slide down the neck from top to bottom fret should take 2 second. ( 1 second would be ideal )Thats seems fast, and most ( say 98% of the time ) fret movement is only a few inches every 1/2 second to every 1 second.
We need some info/metrics on guitar as well as hand to help.Like...Is it a real guitar that should remain functional?If not, what is it made from and what are the dimensions of the fret board?The hand is made of what?And weighs (approximately) how much?Of what material?
No, Not at all.. I'll probably manufacturer the body and neck around what ever infrastructure that is created for the movement, and not the other way around.
I'm not so foolish to think I'm following everything, and not foolish enough to refuse a helping hand. heck yes, I would greately appreciate a drawing.You totally lost me on the flagging , or stopping at each fret.
wait, so the average unhacked servo turns a bit over 180 degrees. If I want 11 inches of travel, I would need a drive pully mounted on a heavy duty servo of about 22 inches in Circumference? or about 7" Diameter? Would that work?
( My head hurts )
Now I have to start all over.
I have Brookshire VSA 4.0, and will probably upgrade to the latest version buy programing time for this project.
So if your original calculations were off by a factor of 10... I'm back to asking if an RC servo will do the trick. ( Don't throw anything at me, just asking )LOL
