09:54 treats how hard would it be to make a robot that I could code to automate smartphone gui's?
11:05 DarkDaemon Hey there
11:05 DarkDaemon i was getting help earlier in #electronics but i couldn't find a good solution, i was hoping to try my luck here
11:06 DarkDaemon i need suggestions on a relatively cheap (<$5) servo which is quiet
11:09 DarkDaemon it needs to be able to lift <50 grams
11:09 LoRez so 10g is enough?
11:09 DarkDaemon sure
11:09 DarkDaemon i can try reducing the size
11:09 DarkDaemon s/size/weight
11:10 DarkDaemon it needs to be quiet though is the issue, its going to be sitting on a computer desk beside a user and if its constantly in use, a usual servo would get annoying very fast :P
11:10 DarkDaemon i'm also open to other ideas, such as dc motor with position control/feedback
11:11 DarkDaemon but i don't think dc motors can retain the torque
11:32 LoRez stepper motor
11:34 DarkDaemon with microstepping?
11:34 LoRez why would it need microstepping?
11:35 DarkDaemon noise reduction
11:38 LoRez holding it in place doesn't make any noise other than the induced noise your pwm drivers may cause.
11:41 DarkDaemon LoRez: thanks for the help, but someone in #electronics just added to my other idea of a dc motor
11:41 DarkDaemon i think i'll try the dc motor + control/feedback
11:42 DarkDaemon and have it compensate for the movement in software
11:42 DarkDaemon and have it compensate for the movement caused by a hanging weight in software*
11:43 DarkDaemon this way i can get input too if i want to get/record the rough positions of the weight then replicate it

15:44 treats How hard would it be to program a smartphone ui automation robot? I have limited exposure to robotics
16:53 DarkDaemon treats, what do you want the robot to do?
16:55 treats version 1 - have up to two points of contact to recreate gestures, spell things out, etc.. version 2 would have the ability to tilt the phone to interface with the accelerometer
16:55 treats DarkDaemon:
16:58 DarkDaemon i'm sorry, im confused by both
16:58 DarkDaemon how do you intend to recreate gestures or spell things out?
16:58 DarkDaemon with a pen and some sort of robotic hand?
17:01 DarkDaemon also is this an existing robot device/toy that you just want to program? or is it one you want to develop
17:06 treats I assumed this is something I would need to create, but that would be awesesome if some hand type device existed.
17:07 DarkDaemon there are tonnes at hobby shops
17:56 Skwint treats - if you want gestures and a pen I recommend attaching a touchscreen smart phone to the robot
17:56 Skwint it can talk with bluetooth or something to the controller
