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:

  1. Misuse: Incorrect installation, reverse polarity, or exceeding voltage limits.

  2. Unauthorized Modification: This explicitly includes soldering, cutting pins, modifying the PCB, or flashing unauthorized/beta firmware that "bricks" the device.

  3. Physical Damage: Drops, moisture/water damage, or electrical surges (lightning).

  4. 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:

  1. Authorization: Contact us at info@openelab.io before returning any item. Returns without prior authorization will not be accepted.

  2. RMA Number: We will provide you with a Return Merchandise Authorization (RMA) number and the correct return address.

  3. Packing: Ship the item back in its original packaging with the RMA number clearly marked on the shipping label (not on the product box).

  4. Tracking: We strongly recommend using a trackable shipping method. OpenELAB is not responsible for returns lost in transit.

The Unitree Go2W U4 is a wheeled robotic dog platform for AI navigation, smart mobility, and compact robot development. Based on Unitree's official Go2-W family, it gives developers and educators a practical mobile robot for navigation logic, patrol demonstrations, smart control experiments, and AI robotics training.

The official Unitree Go2-W product page lists the platform at about 70 cm x 43 cm x 50 cm, about 18 kg, 33.6 V, about 0-2.5 m/s speed, and 7-inch pneumatic tires. It also lists about 8 kg recommended payload, about 12 kg maximum load, about 1.5-3 hours of endurance, and about 45 degrees slope capability.

Go2W U4 is a good choice for labs, classrooms, and developers that need a compact wheeled quadruped-style robot for AI navigation workflows and smart mobility projects. For software development and integration, Unitree's official SDK ecosystem, including the Unitree SDK2 repository, provides a useful development starting point.

Features

  • AI navigation platform - Go2W U4 is suited for compact navigation, route control, and mobile robot behavior experiments.
  • Official Go2-W family specs - The description uses verified Go2-W platform data from Unitree's official product page.
  • Compact wheeled robotic dog - The robot is listed at about 70 cm x 43 cm x 50 cm and about 18 kg.
  • Smart mobility focus - The wheel-leg layout helps the robot move efficiently on suitable surfaces while supporting robotics control experiments.
  • 0-2.5 m/s speed range - Official speed data supports practical indoor and controlled outdoor route testing.
  • Payload-ready for accessories - Unitree lists about 8 kg recommended payload and about 12 kg maximum load.
  • 7-inch pneumatic tires - Pneumatic tires support smoother movement for wheeled robotic-dog applications.
  • Useful terrain capability - Official data lists about 23 cm stair-climbing capability and about 45 degrees slope capability.
  • 1.5-3 hour endurance - The listed endurance range supports classroom sessions, lab testing, and demonstration workflows.
  • Official SDK resources - Unitree's development ecosystem supports custom software and integration projects.

FAQ

Q1: What is the difference between Unitree Go2W U4 and Unitree Go2W U3?

Both are based on the official Unitree Go2-W platform. Unitree's public Go2-W page does not publish separate U3/U4 parameter tables, so core specifications should be treated as shared Go2-W family values unless a package-specific source confirms otherwise.

Q2: What is the difference between Unitree Go2W U4 and Unitree A2-W?

Go2W U4 is a compact wheeled robotic dog at about 18 kg. Unitree A2-W is based on the larger A2 industrial robot family.

Q3: How fast can Unitree Go2W U4 move?

The official Go2-W page lists about 0-2.5 m/s.

Q4: What is the official Go2-W endurance?

The official endurance range is about 1.5-3 hours.

Q5: What payload is listed for Go2-W?

Unitree lists about 8 kg recommended payload and about 12 kg maximum load.

Q6: What tires does Go2-W use?

The official tire specification is 7-inch pneumatic tires.

Q7: Does Go2W U4 support custom development?

Unitree provides official SDK resources for custom robot software and integration workflows.

Q8: Is Go2W U4 suitable for AI navigation projects?
