In the comments of the Instructable they say 1:10, but they probably mean 10:1.

I have chcked the instructables and only found int the comments that the stepper motors come integrated with a planetary gearbox. 10:1 doesn't seem like enough to get a good resolution without x32 microstepping. And that would reduce torque too much. Not much "source" on this so called open source robot...]]> realthor Polar Machines, SCARA, Robot Arms Tue, 27 Oct 2015 16:17:06 -0400 https://reprap.org/forum/read.php?185,559567,576076#msg-576076 Re: Not RepRap but neat ---- DOBOT https://reprap.org/forum/read.php?185,559567,576076#msg-576076 gmh39 Polar Machines, SCARA, Robot Arms Tue, 27 Oct 2015 10:27:25 -0400 https://reprap.org/forum/read.php?185,559567,574389#msg-574389 Re: Not RepRap but neat ---- DOBOT https://reprap.org/forum/read.php?185,559567,574389#msg-574389 I just stumbled upon this one http://www.sainsmart.com/diy-4-axis-servos-control-palletizing-robot-arm-model-for-arduino-uno-mega2560.html but looking more there are so many similar designs...

I wonder what gear reducer does Dobot use... It might be some sort of planetary compact gearbox but that would have too much backlash for the claimed accuracy... maybe some sort of cycloidal gearbox?]]> realthor Polar Machines, SCARA, Robot Arms Fri, 23 Oct 2015 07:21:08 -0400 https://reprap.org/forum/read.php?185,559567,569490#msg-569490 Re: Not RepRap but neat ---- DOBOT https://reprap.org/forum/read.php?185,559567,569490#msg-569490 Nevertheless impressive.]]> realthor Polar Machines, SCARA, Robot Arms Mon, 12 Oct 2015 07:13:33 -0400 https://reprap.org/forum/read.php?185,559567,566830#msg-566830 Re: Not RepRap but neat ---- DOBOT https://reprap.org/forum/read.php?185,559567,566830#msg-566830

DOBOT’S SERVOS BRING IT THE POWER TO MOVE FREELY WITH A REPEAT ACCURACY OF 0.2MM.

Sounds pretty good indeed.(tu)]]> realthor Polar Machines, SCARA, Robot Arms Sat, 26 Sep 2015 16:09:35 -0400 https://reprap.org/forum/read.php?185,559567,559567#msg-559567 Not RepRap but neat ---- DOBOT https://reprap.org/forum/read.php?185,559567,559567#msg-559567 DOBOT
