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.

Unitree A2 Pro Quadruped Robot with Advanced AI Power and Mobility Control

Unitree A2 Pro Quadruped Robot with Advanced AI Power and Mobility Control

43.999,00 €

The Unitree A2 Pro is the higher-feature configuration in the A2 industrial quadruped robot family, built for advanced AI development, sensing-heavy field robotics, industrial mobility research, and custom robotics integration. It keeps the same core A2 mechanical platform while adding a richer perception and expansion profile for teams that need stronger environmental awareness and more room for industry-specific development.

According to the official Unitree A2 product page, the A2 Pro uses a 12-DOF legged structure with about 180 N·m maximum joint torque, about 42 kg weight with batteries, dual hot-swappable batteries, and long walking endurance. The A2 Pro row specifically lists LiDAR × 2 + HD Camera × 1 and an IP56–IP67 ingress protection range, with core components rated IP67.

For robotics researchers and system integrators, Unitree A2 Pro is especially useful when the project needs a durable quadruped base, onboard development compute, official secondary development support, and stronger sensor coverage than the standard Unitree A2. It is a practical platform for autonomy, inspection, mobility control, and AI-powered robotics workflows that must move beyond lab-scale prototypes.

Features

  • Advanced A2 Pro configuration - Unitree A2 Pro is the higher-feature A2 family option for custom industry solutions, advanced robotics development, and demanding field use cases.
  • Dual-sided perception - The official A2 Pro row lists LiDAR × 2 + HD Camera × 1, providing richer sensor coverage than the standard A2 configuration.
  • Industrial-grade quadruped platform - The robot uses an aluminum alloy and high-strength engineering plastic structure for a balance of durability, weight control, and field-ready mobility.
  • High-torque 12-DOF motion system - A2 Pro uses 12 joint motors and is listed with about 180 N·m maximum joint torque for strong legged movement.
  • Long walking endurance - Official data lists more than 5 hours of continuous unloaded walking and approximately 20 km range under the stated no-load condition.
  • Payload-ready operation - With a 25 kg walking load, A2 Pro is listed for more than 3 hours of continuous walking and approximately 12.5 km range.
  • Hot-swappable dual batteries - The dual-slot, dual-battery architecture supports battery swapping without stopping the robot, helping extend mission workflows.
  • Expanded optional modules - The A2 Pro row lists optional expansion paths for wireless vector follow, GPS, 4G, and a high-computing-power expansion dock.
  • Enhanced protection rating - A2 Pro is listed with IP56–IP67 ingress protection, with core components rated IP67, making it better suited to demanding environments than the standard A2 rating.
  • Development-ready compute - The standard configuration includes an 8-core high-performance CPU for the platform and an Intel Core i7 for user development.
  • Rich integration interfaces - A2 Pro provides RS485, CAN, Gigabit Ethernet, USB3.0 Type‑C, and 12V / 24V / BAT power output options.
  • Secondary development support - Unitree lists secondary development as supported, making A2 Pro suitable for research teams, robotics developers, and industrial integrators.
