Фром зэ боттом оф май харт, комрад. Ох, уж этот непередаваемый шарм акцента из фильмов 80-х

[@RomaxSinergy]

Почему сейчас вся точная механика доступна только на этих грубых шаговиках и неточных сервоприводах ? Почему высокоточные абсолютные энкодеры до сих пор доступны только концернам с астрономическими бюджетами? Под заказ море таких вещей, но они даже близко не по карману большинству DIY-щиков. Это сильно упростило бы разработку подобных устройств и позволило питать их кинематику от любых силовых агрегатов от простейших коллекторных DC-моторов до гидравлики и пневматики, или пружин с переменным гуковым коэффициентом.

anyone else hear the powersupply slowly ramping up as more and more motors started to move, and start to think that their computer's cpu fan was ramping up instead?

Great project and videos, thank you for that. I was wondering: do you have end stops or limit switches to reference a home or start position for the stepper motors?

[@theodornitu]

Nice! You could have changed just the motor wires (invert the phases) by connector on RAMPS, this way the program would be compatible with the trinamics one :) Nice work, keep it up!

Great Project! Clean and works as designed!! - - - - I have a question about heat: What does it mean when the motors and the motor driver get kind of hot? It works as programmed on the Arduino for a minute and then starts to malfunction in timing/delay. Is it possible the wire gauge is too small? Should I run a wire from the Arduino pin Vnn or 5v or both?? I am running a 17HS08-1004S pancake NEMA 17 (only 20 mm thick motor) and L298N driver with an Arduino UNO separate power supplies. Thanks for any suggestions.

I think this robot arm is significantly precise to be more than just a toy. But I did not yet find the good application for it. If you have a good idea, please share. I plan to add a gripper to it, and, probably, some computer vision (I already bought depth camera, but this is for future).

Don´t you have any interference problems with all those unshielded cables in parallel? What about homing switches on each axis? What´s the repeatable and absolute accuracy? How stiff are the axis at nominal load? keep up the good work! Love every part of it

[@jamesclerkmaxwell6196]

Nevermind, just found your vid regarding accuracy

[@Skyentific]

Thank you for you comments. Fortunately, I don't have a problems with unshielded cables. I wanted to use shielded cable at the beginning, but soon I realised that I don't have much space for shielded cables. I don't have homing switches. And for the moment it works just fine without them.

[@Almog6k]

Your work is amazing. You are truly an inspiring person. Can you share where did you learn 3D design and electronics? Again, amazing work.

[@Skyentific]

Thank you for your kind words. I don't have one place where I learned this. I used 3D design and electronics for many years, and only recently I decided to share this on youtube. I think that, the best way to learn this is to start building something. And when you have a problem try to learn and overcome this problem. Because learning without concrete project is complicated.

[@Alexsshittyelectricals]

Please can you give a wiring diagram that's easy to follow, showing things going from Arduino to drivers and stuff

[@JamesKruseArtist]

do you have a detailed schematic of the ramps/tb6600 wiring and resistors list? I found the DB25 pin out on your github for inside the robot. thanks!

[@eoadev2602]

Hi, first of all a bravo for your great engineering work! I am gathering the materials needed to build a copy of the robotic arm you designed. I am working on an open source project where the idea is to have a robotic arm co-operate with a 3D Printer and as soon as the print is over, have the robotic arm pick the pieces and place them on a box nearby so that the 3D Printer can continue to the next print. I have some questions about the build: 1. What awg wiring did you use for each stepper motor? 2. Do you think, if i print the carbon fibre components in ABS would be ok? 3. Do i have to drill the holes on the metal rods or can i order them drilled? 4. What type of glue do you use to glue the plastic parts together? Thank you in advance

Very nice little guy. I will start to design my own based on this one, I will just upgrade some parts, make it more pocket robot if thats no problem. I like the 4th axis motion delivery, you have room in-axis to take the wires out. Mine big one have there a planetary gearbox and i have a lot of wires outside, that doesnt look that nice. Keep up the good work. I'm sorry that i didnt watch every your vid, because i do not have a lot of time. Maybe the anwser is somewhere but... are those steel plates with carbon sticker or carbon plate?

[@manoxyde]

Hello, I'm french and I have finished the robot but i'm stuck with the wiring ! On the video, it seems you have wires from pins 39 (blue one) to pin 53 (black one) but I don't see any correspondence in the arduino code v1.2 or V2. Can you tell me which code I have to use with the news electronics (Ramps 1.4 and TB6600) and what is the correspondence to your wires black and brown (53,51) ? I think on your video the brown wire (Pin 51) is the ENA for the motors 1,2,3 and the black one (Pin 53?) normally should be the ground for ENA - DIR - PULL -. I really don't understand if i'm wrong or if there is mistake on the video. Can you help me or someone reading my comment because i'm really stuck. Thank you very much

[@grandecatastrophe]

Hey, Thanks again for this amazing series of videos. I am going to build one myself and have already ordered all the necessary parts. Can you please tell me about the power supply I can get?

[@Skyentific]

Hi. Thank you for your kind comment. You would need power supply with the voltage between 12V and 19V and with the power higher than 60W. For one robot I use 19V 60W power supply (from old laptop), and for another robot I use 14V 200W power supply (from battery charger).

Have you looked into modifying the arduino's timers in order to change the sound and volume of the system?

[@matthewferos]

would the belts be a weak point in this design. You have a very bulky frame with these thin belts supporting the weight.

[@dekutree64]

With so little gear ratio, the motors would probably overheat before reaching the belt's torque limit.

Hi Skentific! Love the robot. I’ve designed an arm which is quite different to this, but uses the same electronics.

[@damlic11]

Your acceleration curves are a bit strange, does it have a purpose?

[@Skyentific]

What is strange about my acceleration curves? :) They are not optimised, but why do you think they are strange?

[@damlic11]

I might be wrong but it seems to me that it is a smooth acceleration till around 2/3 the final speed and tham it jumps instantly to fhe finall speed

[@damlic11]

You can see it best at around 13:14

[@Skyentific]

I see! Now I understand what do you mean! :). This is nonlinear acceleration. It does not jump, but it accelerates slowly at the beginning and afterwards it accelerates faster. This first movements are there just to bring the robot to the home position (movements of joint 2, joint 3 and joint 5). That is why I did not bother to make proper acceleration. So it uses this non constant acceleration only to go to the home position but during other moves (down, forward, backward, left, right, right, left, upward) it uses proper acceleration.

super super super idee...100% Best...

[@pd.dataframe2833]

if the belt and pulley system can give zero backlash... why do industrial robots use harmonic and cycloidal gears which are very expensive

[@dekutree64]

Much higher gear ratio. Robot arms typically don't need high speed, but do need high payload capacity. This design is excellent for being low cost and high precision (most other affordable arms use planetary gears, which are pretty useless for this application due to backlash), but it can't carry much weight.
