EM4 + E1: The Preferred Configuration Accelerating Robotaxi Commercial Deployment

RoboSense's EM4, the industry's only automotive-grade, high-channel-count digital front LiDAR in mass production, pairs with the E1, the only automotive-grade, fully solid-state digital blind-spot LiDAR also in mass production, to form the optimal LiDAR pairing. Together, they provide long-range precision and near-field blind-spot elimination, delivering a dual-perception safeguard that accelerates the large-scale commercial deployment of Robotaxis.

Since the beginning of this year, policy support, capital injection, and industry collaboration have collectively accelerated the commercialization of Robotaxi services. Leading Robotaxi companies have entered large-scale validation stages, scaling their fleets to the thousand-vehicle level. The capital market also offers positive outlooks: Frost & Sullivan predicts the global Robotaxi service market will reach $66.6 billion by 2030 and expand to $352.6 billion by 2035. Goldman Sachs expects that by 2030, more than 500,000 Robotaxis will be in operation across over 10 cities in China, with top-tier cities potentially achieving profitability as early as 2026. All signs indicate the tipping point for large-scale Robotaxi commercialization has arrived, ushering in a trillion-yuan market boom.

Scaling Robotaxi Deployment Demands Enhanced perception

1.Upgraded Omnidirectional Perception for Dynamic Scenarios

Take roadside passenger pickup as a typical scenario: to safely pull over, a Robotaxi must accurately predict the paths of cars and two-wheeled vehicles approaching from the rear-right side. In such cases, the vehicle moves slowly, and the lane-changing process takes time—requiring it to avoid potential conflicts with fast-approaching traffic behind. Traditional solutions like corner radars or rear-view cameras are insufficient due to their limited perception data. Even short-range LiDARs often fail to capture the precise speed and trajectory of nearby moving targets, hindering the Robotaxi’s ability to make proactive decisions and posing risks to operational safety.

Currently, RoboSense combines four EM4 LiDARs with four E1 blind-spot LiDARs to build a high-definition, no blind-spot perception system that solves Robotaxi’s sensing challenges. The EM4 sensors are installed on the front, rear, and sides of the vehicle, accurately detecting distant cars, two-wheeled vehicles, and other road users around the Robotaxi. Even during slow, time-consuming lane changes, they continuously provide precise positioning data, offering reliable input for the vehicle’s system to make proactive decisions and ensuring safe and comfortable driving in dynamic traffic. Meanwhile, the four E1 blind-spot LiDARs focus on the 360° short-range blind spots around the vehicle, eliminating perception blind spots with dense point cloud coverage. This dual-layer solution—“long-range precise detection plus short-range blind-spot elimination”—not only meets the continuous, full-range perception needs of roadside passenger pick-up scenarios but also demonstrates strong advantages in Robotaxi’s ability to generalize across diverse environments.

2. Breaking Through Small Object Detection Limits

3. Enhancing Operational Capability in Complex Scenarios

These scenarios represent just the tip of the iceberg in the complex operational environments Robotaxis must navigate. Efficient and safe commercial deployment requires not only handling well-lit roads with stable traffic, but also frequently responding to unstable flows, shifting lighting, and unexpected events. This places urgent demands on high-performance, highly robust LiDAR to ensure operation under all conditions and continuously improve perception stability and reliability.

Mature Technology Enabling Scalable Robotaxi Operations

RoboSense’s high-performance digital LiDAR, exemplified by the EM4, has proven its technological maturity. In the second half of 2025, customized LiDAR products built on the EM platform entered mass production and are being deployed in multiple passenger vehicle models set for official market launch. With a high level of product readiness, they fully meet the stringent demands of large-scale Robotaxi deployments — once again setting the industry benchmark for high-channel-count, long-range digital LiDAR.

The mass-produced EM4, combined with the world’s only fully solid-state blind-spot LiDAR in large-scale vehicle production—the E1—delivers precise, omnidirectional perception capabilities for Robotaxis in 2025. This powerful combination ensures continuous support for Robotaxis as they expand into more cities. Thanks to RoboSense’s continuous innovation in core technologies, strong in-house chip development capabilities, and the EM platform’s highly customizable architecture, the company is able to respond swiftly to the evolving functional and scenario-based requirements of Robotaxi applications.
