MiraBot Lite is our modern reinterpretation of the classic OSR2+ 3-axis concept.
Rather than changing the motion style players already enjoy, we rebuilt the surrounding structure to make the experience smoother, quieter, and more polished—while maintaining the open, mod-friendly spirit of the original.
A Smarter, Cleaner 3-Axis Architecture
The OSR2+ remains a favorite in the DIY community, but its open-frame layout naturally brings limitations such as tight clearance between the pitch link and arm, and occasional contact between the Twist module and the chassis.
MiraBot Lite addresses these points with a compact, enclosed design that preserves compatibility while improving real-world usability.
If you like the OSR2+ motion style but want a cleaner, quieter, and more refined version of it, this sits exactly in that space.
Key Improvements at a Glance
• Compact, Balanced Body — Mountable or Handheld
By relocating the pitch servo inside the chassis and refining the geometry, MiraBot Lite achieves:
- A compact, refined body with universal 75mm VESA mount support
- Balanced weight distribution that makes handheld use surprisingly comfortable
- An optional ergonomic grip for those who prefer extended handheld sessions
The enclosed shell minimizes protrusions and increases structural rigidity.
• Smoother Motion With Significantly Lower Noise
The internal mechanics were redesigned to reduce friction and acoustic output.
Pitch link – arm spacing increased from 20mm → 50mm, eliminating rubbing and providing noticeably smoother travel—even at higher speeds.
The pitch arm now stays fully within the chassis footprint, preventing rearward collisions during backward tilt.
Together with a reinforced structure, optimized mechanical clearances, redesigned Twist internals, and 35kg coreless servos, the Lite delivers a much quieter, softer, and less “mechanical” sound profile in real-use conditions.
Measured noise:
≈ 45–55 dB during full-range motion including Twist.
< 40 dB with Open Receiver
(Recorded at 50 cm with a 400g onahole load.)
• User-Friendly Maintenance & Modding
The simplified internal layout makes modding and repairs straight forward:
- Servo replacements require only a few screws
- Clean, durable internal wiring
- Hot-swap Twist module—instantly removable and replaceable with the open-receiver
Ideal for tinkerers and long-term reliability.

Built Together With the Community
MiraBot Lite reflects real user feedback and the qualities many of us look for in a refined 3-axis robot.
If you have ideas, suggestions, or feature requests, we’re always interested in hearing them.
We’ve also put considerable effort into improving the SR6-style architecture, and the response so far has been very encouraging.
As a way to give back to the community, we’ll continue releasing free software tools, utilities, and other useful resources.
