MiraBot Lite — A Compact, Quiet, and Refined Evolution of the 3-Axis Stroker Robot

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
  • For hands-free use, the compact desk mount provides adjustable angles and supports a variety of stable setups.

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.

Looks good, I’m hooked! But from where is the device shipped - Japan? Do you by any chance have a partner in EU to handle the customs or is the importing process left on the shipping company (and therefore charged extra)? Boring questions, but I’ve recently had some bad (and costly) experiences with import of adult goods from Japan unfortunately. :frowning:

Thanks for the question — and I totally understand your concern.

To improve delivery speed and reliability for our international customers, we now use an overseas fulfillment center for EU orders.
All items still go through our usual in-house quality control before shipping, so there is no change in product standards.

Our logistics partners handle the import process smoothly in most regions, and customers in Europe generally do not need to pay any additional customs fees.

If you’d like, feel free to send me your country and region via private message, and we can double-check the exact delivery conditions for your area. :grinning_face:

That handle looks pretty cool.
I tried making something similar for my OSR2+ before, but honestly it didn’t feel great to use. :joy:
This Lite’s shape looks a lot cleaner and seems like it would be easier to hold.I’m just curious what it’s like in actual hand-use , does it feel comfortable? And is it tiring to control it that way?

6

Thanks for the comment!
With the handle attached, the MiraBot Lite weighs around 900g for the Twist version, and about 600g for the Open Receiver (non-Twist) version — plus the weight of the onahole, of course. It’s lighter than it sounds, and holding it is no problem at all.

For most adults it should be pretty easy to hold, and the symmetrical design makes it more stable and easier to control while it’s running. We’ve tested this thoroughly on our side as well.

I’ll post a demo video a bit later so you can check out how it looks in actual use.

Do you guys ship to Australia?

I want to buy your products, especially the SR6 with the full set. Unfortunately, I need to save up since I’m planning to upgrade some things. :upside_down_face: … I will 100% buy it :sweat_smile:.

9

Yes, absolutely — we ship to Australia!
Delivery usually takes around 9–12 days, and we’ll provide a tracking number once the package is on its way.
If you have any questions about shipping times or accessories, feel free to ask!

Thanks so much ! I really appreciate your interest!
And no worries at all, upgrading your setup takes time and planning. Take it at your own pace. :blush:

Whenever you’re ready to order, just let me know — I’ll make sure to include a little extra gift in your package as a thank-you for your support. :raising_hands:

I am intrigued with this product. I may be looking to purchase a new device soon.

I have no experience with OSR. How well does this work with the Quest 3? Will it connect with DEOVR and Heresphere?

What shipping company do you use for the US? I am wondering if i can divert the package to a pickup location, if needed.

12

Thanks for the questions — happy to clarify!

1. Quest 3 Compatibility & VR Support
Absolutely — Quest 3 is the most common headset among OSR users, and pairing it with MiraBot gives you excellent immersion.
You can use it with DeoVR and HereSphere via MultiFunPlayer just like any OSR/SR6 setup.
(There are several helpful setup guides on the EroScripts forum, and we’ll also publish our own instructions on our official website soon.)

2. Shipping to the US
We mainly ship through USPS, though depending on your region the final delivery may switch to FedEx or UPS.
I’m sorry — we can’t designate a pickup point on our side, but once your local carrier contacts you, you can usually request pickup options directly with them.

If you have any other questions or need help getting started, feel free to ask anytime — happy to help. :slightly_smiling_face:

This looks fantastic. Does it connect to intiface?

14

The site states the max load on the open model is 900g and the twist model is 700g (without the twist). Does that mean it is even less with the twist?

My only experience is with fleshlight and keon sleeves. I get the impression those will be incompatible based on weight. I would like to get a better understanding of the sleeves. I enjoy the depth of those and this seems like the compatible options are more shallow.

15

Thanks! Glad you like it. :grin:
At the moment, MiraBot doesn’t support Intiface (since it’s primarily single-axis), but we’re definitely exploring possibilities for broader compatibility in the future.

If we move forward with Intiface support, I’ll share updates here.

17

Thanks for the comment — and sorry for the confusion! :sweat_smile:
Just to clarify, the recommended load limit is the same for both the Open and Twist models. The Twist module itself weighs about 200g, so that weight is simply counted into the usable load.

In other words, the overall structural capacity is identical — the Twist unit just takes up part of that allowance. Based on our testing, the Twist model can handle a Fleshlight without any problems, so you should be able to use it normally. The recommended limit also isn’t a strict cutoff; going a bit above it or using a heavier sleeve for reasonably short sessions is generally fine.

If you have any other questions about sleeves or compatibility, feel free to ask anytime — happy to help! :grin:

Thank you so much for the support!
I just noticed a new Lite order come in — there wasn’t a forum ID in the notes, but I’m guessing that’s probably you. The handle will be included in the package as promised.

By the way, your work is awesome. Already followed you.Looking forward to seeing more from you!:wink:

Hello. I have been getting more interested in possibly upgrading to a multiaxis device recently. Both the Mirabot lite and the S6 seem attractive. They both seem like they would make some things I find intimidating with the multi axis devices a bit easier. The app looks really useful too. I am very intrigued, and will be thinking intently about this one. I think I might be your target audience to a T.
