Anyone know how the accuracy of this compares to the similar-cost adamb314/ServoProject arm? [1] It utilizes a servo mod adding dual encoders to compensate for backlash and achieves accuracy of +/- 0.05mm (enough to thread a mechanical pencil lead in and out of the tip of a pencil). [2] He's been working on the project for 5 years, with significant improvements still in the last year. [3][4]

- serf 3y agoit should be similar given similar construction; one of the reasons dynamixels tend to be pricey is the dual inboard encoder setup. if price is a factor then a servo+encoders setup will always be cheaper; there are some dirt cheap encoders out there for the creative hacker. dynamixels offer a crappy value compared to DIY solutions, they're just easy to use off-the-shelf and have nice features that aid construction.. but hardly anything game changing.

When I worked on liquid handlers a decade ago the fully integrated servos were at least ten times as expensive as they are now. Every time I step away for a few years and jump back in, there seems to be at least a half dozen game changing pieces of hardware on the market.
