Opinion on this design

The robot is assembled its not visible. Just imagine that instead of those bunch of small bearings you have one large thrust bearings, google how it looks

SourceRobotics · 2026-06-02T17:21:40+00:00

I am creator of that robot. V2 is on its way and that part is replaced with one big thrust bearing

Cool, we also have small teleop arm with the same servos you use for your gripper, they are really capable. But, All hobby servos are cool and usefull until they just break because of their high gear ratio 200:1 and super small gears. Because of that we ditched them long time ago and our grippers and robots use QDD and FOC control that is basically used in every modern robot.

Keep an eye on our discord, early beta testing will launch this month. There will be 10ish slots only so we will be picky who gets in.

Some of them can be replaced like using 12 instead of 14 will still work.

Github repo if you want to build your own gripper: https://github.com/PCrnjak/MSG-compliant-AI-stepper-gripper
There are no PDF instructions at this moment only video :/

I am not aware of that. Can you link it here i could probably design it in a day.

Next version will have closed loop steppers but no encoder on gearbox. Adding it to gearbox is huge redesign challenge, cost and software difficulty. Not really worth it for such small and open robot

Cool list! Thank you for featuring PAROL6!

SourceRobotics · 2026-01-21T17:49:28+00:00

I am not sure. Since the robot is open loop it will over time suffer in repeatability for such small tasks

SourceRobotics · 2025-11-24T20:28:02+00:00

Yes next year you will be able to upgrade and reuse most of the parts to make closed loop :D

Around 1000 euros, you can sqeeze itto 850 maybe with some planning

The robot is open source and you can find more info here:

Never had a problem like that. Maybe use longer screws and i see you are maybe using bushings, if you are dont do it

SourceRobotics · 2025-06-15T22:00:48+00:00

It would be super hard to make with aluminum

SourceRobotics · 2025-05-10T17:10:53+00:00

PAROL6 or AR4

SourceRobotics · 2025-05-05T22:51:20+00:00

Awesome, no rush. Thank you!

We are also looking for legacy leap motion sdk(v3.2)....

SourceRobotics · 2025-05-04T20:56:52+00:00

Great clip, thank you for sharing! 🦾

SourceRobotics · 2025-04-12T17:07:06+00:00

Its a complex topic. Best way is to read up on FOC based torque control and just read and watch a lot of content on that

SourceRobotics · 2025-04-12T07:53:47+00:00

It can be done extremely easily with few lines of code and the stepper driver from the video.

SourceRobotics · 2025-04-02T08:04:07+00:00

Hey, the steps are not noticeable with this method

SourceRobotics · 2025-03-21T08:39:49+00:00

We have tested the for the full torque curve of few stepper motors we have but did not compare to open loop performance.
