PAROL6 Robot arm Wrist and Forearm assembly

The wire routing and potential for chafing through the wire insulation is concerning here, particularly at 5:23. Might I suggest a 2.0 version with more consideration for wiring between and through rotating/moving parts?

[@source-robotics]

That is actually not a problem. We have now run the robots for a year and never had a problem. It rotates only 180 degree and has some sloop. If it were rotating more and there was not enough extra wire it would be bad I agree.

Wonderful project! Just started to build my own. Just to clarify, does it means that on the video j4 homing pin is in wrong position? It needs to be 90 degrees on the left?

[@source-robotics]

It needs to be rotated so that it points in the direction where the pneumatic connectors are located

[@source-robotics]

But yes 90 degree to the left

Is this stepper motor have close loop?, im trying to figure it out to get the "Home position" for my project

[@seventySixLab]

oh, nevermind, i shall these limit switchs

[@source-robotics]

@@seventySixLab they are not closed loop, we use limit switches for home position

Hows the torque of the total weight of this small motor + gearbox compared to a motor of the same weight?

[@source-robotics]

This was a design choice, but there might be some motors of similar size that could replace this small motor + gearbox.

Uhmm just to know ¿Did you make all calculations for mechanical deformations and sheesh? Because in my university we saw a little of it (and seems interesting but hella problem to do with all parts)

[@source-robotics]

You need to make cals for motor torques that will be enough to operate the robot. I ignored deformations for robot of this size

[@HeadNSV]

Not so easy at it looks in this Video😂 thanks from Germany

[@source-robotics]

@@HeadNSVIts a difficult build, at what part did you have problems?

[@HeadNSV]

@@source-roboticsmy ABS parts fits very tight. But I can fix this und it is very satisfying. I have no technical backround but I have successfully build a reprap 3d printer many years ago. It takes time but I love to assemble this robotic Arm.

[@HeadNSV]

@@source-robotics i have a question. How can I see how long the pneumatic tubes have to be?

[@jimbojones6206]

ABS / ASA tends to shrink to 99%

[@ruisuter6139]

Nah way bro 6 years of research... And i want to do a robot manipulator like this in 2 years (im still in bachelor's degree) pls tell me ure already have phd or something xD because this for me is crazy

[@source-robotics]

I designed my faze4 robot when i was still doing bachelor's degree. We are doing these robots as a company now.

@@source-robotics no way xD some day I will catch up with u bro xD sheeesh

@@ruisuter6139No need to worry, you will some day :D
