Guarantee & Return Policy

Effective Date: December 10, 2025

At OpenELAB, we are committed to providing accurate product descriptions and high-quality electronics. The following policy outlines your rights and obligations, designed to be fair to both our customers and our business operations globally.

1. Warranty Policy

A. Standard Limited Warranty (Global & US)

For customers in the United States, Asia, and other non-EU regions:

Warranty Period: OpenELAB provides a 12-month warranty from the date of delivery.
Coverage: This warranty covers defects in material and workmanship under normal use.
Resolution: We will repair or replace defective units at no charge.

B. Statutory Rights for EU/UK Customers (EU Compliance)

If you are a consumer residing in the European Union or the UK purchasing from our global site:

Statutory Guarantee: You are entitled to a 24-month statutory guarantee for conformity defects present at the time of delivery, in accordance with EU consumer protection laws.
Relation: The Standard Limited Warranty (Section 1.A) applies in addition to, and does not replace, your statutory rights.

C. Warranty Exclusions (Applies to ALL Regions)

Warranty coverage is VOID if the damage is caused by:

Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.
Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.
Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).
Normal Wear & Tear: Consumable parts (e.g., batteries), unless defective upon arrival.

Note: For non-warranty repairs (e.g., customer-induced damage), we may offer repair services for a fee. Shipping and diagnostic costs will be borne by the customer.

2. Return & Refund Policy

A. Return Window

Standard: You may request a return within 31 days of receiving your order.

B. Refund Conditions & Restocking Fees

To protect against policy abuse, the refund amount is strictly determined by the condition of the returned item.

1. Full Refund (100%)

The item is Brand New, Unopened, and Unused.
The original packaging is intact and sealed.
All accessories are present.

2. Partial Refund (Restocking Fee / Value Depreciation)
If the item is returned in a condition that prevents it from being sold as new, OpenELAB reserves the right to deduct a Restocking Fee (for US/Global) or Compensation for Loss of Value (for EU) from the refund amount.
Deductions apply if:

Signs of Use: Visible scratches, mounting marks on screw holes, or fingerprints.
Damaged Packaging: Original box is torn, written on, or missing.
Technical Modification: The device has been soldered, permanently installed, or flashed with unauthorized firmware.
Broken Seals: Anti-static bags or security seals have been opened.

Depending on the severity of the usage/damage, the deduction may range from 15% to 50% of the product price. Items damaged beyond repair due to misuse will not be refunded.

C. Shipping Costs

Defective / Wrong Item: OpenELAB covers the return shipping cost.
Customer Remorse (Changed Mind / Ordered Wrong Item): The customer is responsible for all return shipping costs to our designated return center (located in the US, Germany, or China, depending on your region). Original shipping fees are non-refundable unless required by local law.

3. Return Process (RMA)

To ensure a smooth return process, please follow these steps:

Authorization: Contact us at info@openelab.io before returning any item. Returns without prior authorization will not be accepted.
RMA Number: We will provide you with a Return Merchandise Authorization (RMA) number and the correct return address.
Packing: Ship the item back in its original packaging with the RMA number clearly marked on the shipping label (not on the product box).
Tracking: We strongly recommend using a trackable shipping method. OpenELAB is not responsible for returns lost in transit.

BrainCo Dexterous Hand Revo 3

The BrainCo Dexterous Hand Revo 3 is a next-generation robotic dexterous hand for embodied AI, humanoid robotics, manipulation research, and advanced end-effector development. Public launch reporting describes Revo 3 as a 21-degree-of-freedom hand built around a direct-drive, backdrivable joint architecture for more precise and compliant manipulation than simple open-close grippers.

The BrainCo Revo 3 dexterous hand is available in three configuration variants—U21, U21T, and U21VT—all built on the same 21‑DOF direct‑drive architecture, but differentiated by their tactile and interaction capabilities. The U21 variant provides the standard 21‑DOF configuration suitable for general integration needs. The U21T variant enhances this with tactile sensing for applications requiring contact or pressure detection. The U21VT variant further expands the system with a visual‑tactile fusion package, offering the highest level of interactive feedback. Before integration, please confirm the hand orientation (left/right) and the final interface package, and refer to the configuration sheet for tactile or visual‑tactile module details.

Features

21-DOF dexterous manipulation - BrainCo SDK release notes confirm Revo3 support with 21-degree-of-freedom motor control.
Direct-drive backdrivable design - Public launch reporting describes Revo 3 as using direct-drive, backdrivable joints for precise and compliant robotic manipulation.
Advanced tactile direction - Public launch reporting describes full-palm tactile sensing and fingertip visuotactile sensing on Revo 3 configurations.
Multiple store variants - Available in U21, U21T, and U21VT SKUs for different Revo 3 configuration choices.
Revo3 SDK support - BrainCo's official SDK changelog lists Revo3 Basic, Pro, and Ultra device support.
Python and C++ development - The official SDK documentation provides programming support for Python and C++ workflows.
Revo3 example programs - Official SDK release notes list Revo3-specific examples such as basic motor control, teaching mode, and high-frequency latency testing.
Control-mode development - BrainCo SDK release notes mention Revo3 control support for position, velocity, current, MIT impedance, and damping-related modes.
RS-485 SDK path - BrainCo's official SDK protocol table currently lists Revo3 support through RS-485.
Embodied AI ready - Suitable for humanoid robotics, teleoperation, imitation learning, manipulation data collection, and tactile-aware control research.

FAQ

What are the three variants for this BrainCo Revo 3 listing?

The Shopify product includes U21, U21T, and U21VT variants with SKUs BrainCo-Revo3-U21, BrainCo-Revo3-U21T, and BrainCo-Revo3-U21VT.

What does the 21 in U21 refer to?

BrainCo SDK release notes confirm Revo3 support for 21-degree-of-freedom motor control, so U21 is presented as the 21-DOF Revo 3 configuration family.

Does the official SDK support Revo3?

Yes. BrainCo's official SDK documentation states that the SDK supports Revo 1, Revo 2, and Revo3 series devices.

Which programming languages are supported?

The BrainCo Hand SDK documentation lists Python and C++ development support.

Which communication protocol should I plan for?

The current BrainCo SDK protocol table lists RS-485 support for Revo3. Confirm the final protocol and connector package for the selected U21, U21T, or U21VT configuration before integration.

Does Revo 3 support tactile sensing?

Public launch reporting describes Revo 3 configurations with full-palm tactile sensing and fingertip visuotactile sensing. Because the full first-party variant matrix is limited, confirm the exact tactile package for U21T and U21VT before ordering or integration.

What Revo3 examples are listed by BrainCo?

BrainCo SDK release notes list Revo3-specific examples including revo3_motor.py, revo3_teaching.py, and revo3_benchmark.py.

Is this suitable for embodied AI research?

Yes. A 21-DOF robotic hand with SDK support is suitable for humanoid robotics, manipulation research, teleoperation, imitation learning, and embodied AI experimentation.

Why are some mechanical specifications omitted?

Variant-specific Revo 3 dimensions, weight, payload, connector model, and complete electrical data were not confirmed from a first-party Revo 3 parameter table during this rewrite, so they are intentionally omitted to avoid mixing in unverified data.
