The rapid evolution of mobile robotics and embodied artificial intelligence has intensified the demand for compact, power-efficient, and highly reliable perception hardware. In response to these industry requirements, Benewake has officially introduced its new SR Series of compact, power-efficient 360° 3D LiDARs. Designed specifically to address the spatial and energy constraints of modern mobile robots, the initial product lineup features the 18-channel SR18 and the 96-channel SR96. With the SR18 model already entering mass production, this launch represents a significant step forward in making high-performance 3D spatial perception accessible for commercial and industrial robotic platforms.

Next-Generation Perception for Autonomous Mobile Systems

The SR Series is engineered to serve as the primary perception system for a wide range of autonomous applications. These include commercial cleaning robots, robotic lawn mowers, quadruped robots, embodied AI platforms, last-mile delivery robots, and industrial mobile robots. By providing a comprehensive 360° horizontal field of view, these sensors enable robots to map their surroundings, localize accurately, and avoid obstacles in real time.

In complex operational environments, mobile robots frequently encounter challenging conditions such as highly reflective surfaces, tight spaces, and sudden changes in terrain. Benewake's proprietary sensing architecture is designed to mitigate these issues by reducing inter-channel crosstalk. This architectural focus ensures stable perception and consistent ranging data, which are critical for preventing localization failures and ensuring safe navigation.

Technical Specifications and Architectural Design of the SR18

The SR18 model is characterized by its compact form factor and low power requirements, making it highly suitable for integration into smaller robotic platforms where space and battery life are at a premium.

  • Physical Dimensions and Power Efficiency: The SR18 measures 71.8 mm in diameter and 64 mm in height, with a total weight of 190 g. Its average power consumption is kept at or below 5 W, allowing developers to implement advanced 3D sensing capabilities without placing an excessive burden on the robot's power budget.
  • Integrated Transmitter-Receiver Architecture: To address the common industry challenge of optical interference, the SR18 pairs each individual laser emitter with a dedicated photodetector. This integrated design minimizes crosstalk between channels, preserving the precise contours of detected objects and maintaining reliable ranging data even in highly reflective environments.
  • Detection Range and Field of View: The sensor is capable of detecting objects as close as 15 cm and extending up to 30 m at 10% reflectivity. It offers a full 360° horizontal coverage combined with a vertical field of view spanning from -8° to +40°.
  • Terrain Adaptation: The inclusion of downward-angled channels is specifically optimized for detecting low-lying obstacles and sudden terrain variations. This capability is particularly beneficial for robotic lawn mowers and outdoor platforms navigating uneven ground, where early detection of drop-offs and descents helps prevent falls and mechanical damage.

Environmental Resilience and Lifecycle Management

To support reliable operation across both indoor and outdoor environments, the SR18 is built to withstand harsh physical conditions.

  • Environmental Protection: The device features an IP66-rated enclosure, protecting the internal optics and electronics from dust and water ingress.
  • Temperature Tolerance: It is rated to operate reliably within a temperature range of -20°C to +60°C, ensuring stable performance in diverse climates and industrial settings.
  • Remote Maintenance: A key feature of the SR Series is its support for remote firmware updates. This capability allows operators to deploy feature enhancements and performance optimizations over the air, eliminating the need for physical hardware replacements or on-site servicing.

Market Strategy, Pricing, and Global Distribution

Benewake's commercial strategy for the SR Series emphasizes affordability and global accessibility to encourage widespread adoption.

  • Pricing and Availability: The SR18 is priced at US$299, positioning it as a highly competitive option for developers and original equipment manufacturers. Global availability is scheduled to begin on November 30, 2026.
  • Distribution Network: To facilitate global procurement, Benewake is partnering with major international distributors and online platforms, including Mouser Electronics, Amazon, Robu.in, and Alibaba.com.
  • Corporate Background: Founded in 2015, Benewake has established itself as a provider of AI-native perception solutions, utilizing a model-defined hardware approach that integrates optics, mechanical engineering, electronics, software, algorithms, and chip design. The company currently serves customers in more than 90 countries and regions, supporting the global expansion of physical AI and robotics.
