12:43 PM Samian: What do you call a claw that's hanging from a horizontal bar by which claw's arm can move across?
12:48 PM Tom_L: gantry
12:48 PM Tom_L: ?
12:48 PM Tom_L: crane?
01:00 PM zhanx_: Tom_L, gantry crane?
01:20 PM Samian: aha thanks
01:22 PM Samian: I need a super miniature version of that
01:23 PM Samian: for a conveyor about 10 inches wide
01:23 PM Samian: I want a gantry crane about 10 inches over the conveyor
01:27 PM Samian: something light and fast
01:30 PM Samian: hmmm maybe instead if I had an array of pencil sized poles that I could programmatically make go up and down
01:30 PM Samian: that would be ideal
01:30 PM zhanx_: continuous servo for the lift
01:31 PM Samian: continuous servo?
01:32 PM Samian: I have fries going over a conveyor belt. If any are crossed, I want a pin to drop that'll push the top fry off as it goes through the conveyor
01:32 PM Samian: I want an array of pins.
01:32 PM Samian: doesn't need to be pins, could be pencils for all i care
01:34 PM Samian: rods
01:35 PM Samian: something that can drop and go back up very quickly
01:36 PM Samian: in a 10th of a second
01:39 PM Samian: high speed linear actuator? is that what I need
01:40 PM Samian: yesss something like this: https://www.youtube.com/watch?v=bh5q1eW_LSc
01:40 PM Samian: except not in a tube
01:41 PM Samian: can I build one myself?
01:41 PM Samian: maybe I need to buy a book on how actuators work?
01:44 PM Samian: hollly crap
01:44 PM Samian: https://www.youtube.com/watch?v=08zM0pswP14
01:44 PM Samian: bingo
02:05 PM Samian: where can I get cheap high speed micro linear actuators?
02:27 PM zhanx_: you mean air bursts?
02:51 PM Samian: i guess blowing the fries could work
02:51 PM Samian: it would be less controlled
03:02 PM Samian: zhanx_ I was thinking the rod drops down, and the fry runs into the rod while the fry under keeps moving. So the fry on top skoots off
03:03 PM Samian: as opposed to the rod actually hitting the fry
03:03 PM Samian: like playing pool
03:04 PM Samian: Rather I invisioned something like rods dropping vertically acting likes gates controlling what passes
04:33 PM Tom_L: https://www.youtube.com/watch?v=_HbA8RQKAcg
04:33 PM Tom_L: mmm too late for him i guess
04:34 PM Tom_L: aparently he doesn't know how fast mericans can eat fries!
08:38 PM rue_mohr: heh
08:38 PM rue_mohr: Samiam1999, what have you built before?
08:38 PM rue_mohr: I get the impression this fires project is way over your head...
08:47 PM Tom_L: not a clue
