  Super cool and looks relatively simple!! But with my limited knowledge of using arduino, I'm sure I would get hung up if I try to make one. Wanting to build a simple head or eye movement devise to track the face as a person walks by. Not too concerned about jerking motion of servos. I'd like to compose the program and load to the arduino and remove from the laptop. Would use a typical webcam camera instead of laptop camera. Use 5v PS, relays if needed, etc. Is that possible? Your video shows using Nano 3.0 but circuit diagram shows Arduino UNO. Will either work? I made arduino controlled Halloween props last year that worked great, but I still have limited knowledge.

  To switch to a webcam is as simple as changing one line in the python code, the micro controller should not matter as long as the wiring is that same and the servos are connected to the same IO pins but I have yet to try it. Good luck lmk if you have any other question!

I could buy a tracking security camera from Amazon, but making this devise will be more fun! Besides, I want to learn more about this stuff so I can make more projects. Will let you know if I have any hiccups (I'm sure I will). Thanks

• 
  @owenobrien880421 күн бұрын

  When running the python script the serial monitor cannot be open along with the script trying to sends commands to the Arduino. To fix this you must only have one open at a time. In your case I think making sure to have the serial monitor closed before running the program will fix it

  Fix the axle on both sides. Modify the pen servo holder to a linear actuator that can lower or lift the pen from the paper. Make sure the belts are as parallel with each other as possible

• 
  @randohorsleyАй бұрын

  Keep at it. Even a wooden dowel would work well as a shaft, . Even better if you had a top/bottom roller that were mated with gears to provide opposing drive function, but that would add to the mechanical complexity. At the minimum constrain the opposite side, and for added results, constrain the back of what the paper slides on to the shaft with some springs or something to make sure you get good traction. Your pin could also stand to be transposed a little bit off axis so that the rotation results in more upward movement of the tip, and less horizontal movement of the tip. That would require the servo actively apply torque to push the tip into the paper. Conversely, just print a little channel, and put a rubber tire or whatever on the servo so it acts like a rack and pinion. Put the pen into the vertical channel, which constrains it into just moving up and down, and then the servo can push down on it as needed, though that will likely result in some slippage. This could be fixed with gear teeth or with a linkage.

• 
  @blacklabel6223Ай бұрын

  Making the belts parallel with your axis instead of on an angle will increase your accuracy a lot. You could also put the pen in a tube to travel vertically up and down and have the servo arm drive a pin on the side of the pen up and down.

  @owenobrien8804Ай бұрын

  This works by first having the laptop take an image and generate that into gcode instruction that can then tell the motors to move to specific cordinates on the paper and then when to move the pen up and down. The calculations are done in the universal gcode sender application, and then these instruction are sent to the arduino microcontroller where it then controls the motors with the instructions resulting in movement. This was a fun project to work on the most engineering was definitely in the 3d printed parts and deciding on materials to use!

  For those confused as to what a pen plotter is and what it can do, when hooked up to a computer it can draw out whatever file you ask it to draw, so if it's a bunch of text, it will write that. Same with drawings. However, the most useful feature that isn't making it a knock off DIY printer, is setting it up to follow the contour of a physical object. Doing that will give you a precise template of that object, allowing you to make an exact copy the first time. This is especially great for restoring things that aren't in production anymore

  Hey brotha, just commented on the short but this provided good insight for me to get some ideas. The coat hanger should work as long as you fix it on the right. Still not sure on the necessity of the servo unless you definitely want a dotter, in which case it would work better with the pen on a 1 inch horizontal lever, then drive the servo way less. This will simultaneously allow the pen to overpower the servo a few mm with the torque from being offset (should increase your success rate of pen contact) as well as allowing you to more accurately affix it to the system since the pen itself will rotate much less. Im by no means a pro but I finished mechatronics with a 100 if you have any specific questions 😎😂

•

  Sub the paracord for a large O-ring or plastic tread and gear wheels instead of pulleys. Also theres nothing keeping the paper held to draw it from what I can see, duplicate the paper driving system underneath and run the sheet between 2 lego tires like a two-high rolling mill. Should draw the paper through. Once you have that you can fix your base way easier and just feed it. Also not quite sure of the use of the servo in this application other than removing the pen from the page when youre done

• 
  @owenobrien8804Ай бұрын

  The servo is supposed to pick up the pen when drawing so that it can create drawings that have white space between the lines. I plan to use belts in the next version. Good eye on the lego wheels haha I found they work pretty well. I had to look up a rolling mill and that seems like a great approach im going to try out!

  It's just a DIY printer for CNC enthusiasts. You can use it to turn PDF files into printed texts of course, but you can also use it to draw for you or set it up to follow the contour of another piece, allowing you to make a precise template of that piece, which is arguably the most useful feature of a pen plotter imo

  Can anybody shed some light on a persistent problem I encounter? With code attached to this video and all of the similar face tracking videos, as soon as the python detects a face, the servo motors instantly move away from the target. I know how servo motors work and I can see how the code is supposed to work, however, every Arduino code gives the same result, the servo motors rapidly move away from the identified face.

• 
  @owenobrien8804Ай бұрын

  Could it be that the servo's are wired backwards, like ground goes to positive and positive goes to ground, in that case switching the wiring might switch the direction of the way to motor turns but im not sure. A way to fix this in the code would be reflecting the image before doing the image processing of finding the face

•

  @@owenobrien8804 Thanks, but I have tried both of these. Added code in python to invert the image. Checked the wiring and reversed it. No difference. I know it’s something in my setup, but I can’t see where. Even connected a picoscope and could see the PWM signal changing as the serial buffer was filled, but the servos still flip out and go to odd and arbitrary position.

  The first parameter is string of the file path of the usb device in my case it was /dev/cu.usbserial-110, and then the 9600 is the baud width, this is declared in the arduino code as 9600 and shouldn't have to be changed. To find the first parameter on your own computer when you select ports in the arduino IDE it should say which one you are connected to and by copying that path it should work.

  0:58 - U can C how it's jerking, and that's because of the servos - they've got min 1 degree steps and nothing you can do. maybe only bldc gimbal motors or steppers with microstepping can do it smoother. I'm bashing my head on similar to get my gopro to rotate left/right with the steering wheel of a car, and with servos, even for 50 euros, the image is terrible, jerking like here

• 
  @theredstormer807825 күн бұрын

  Like he said steppers are probably better, but I'd just gear the servos down (or use a linkage) and call it a day. Depends on the use case ofc but I think you'd only need 2/3x to 1/2x the range of motion. Just a thought.
