It uses direct time of flight (DTOF) to deliver angle-and-distance measurements for environmental perception. With 40 m ranging at 70% reflectivity and a 115 g typical mass, S3 brings wide-area sensing to a small robot footprint. Separate dark-target ratings of 15 m at 10% and 5 m at 2% reflectivity make it easier to plan realistic detection envelopes. The 3.3 V TTL UART, 1 Mbps interface supports integration into a suitable host controller. Review the model-specific electrical requirements and official technical documents below, then evaluate the sensor on the actual surfaces, lighting and robot mounting arrangement. Features Model-specific ranging - 0.05-40 m at 70% reflectivity; 0.05-15 m at 10%; 0.05-5 m at 2%. Dense scan acquisition - 32,000 samples/s provides the range measurements used by mapping and perception software. Controlled scan timing - 10 Hz typical; adjustable 10-20 Hz supports repeatable updates of the surrounding scan plane. Angular sampling - 0.1125° typical; 0.1125-0.225° across the scan-rate range defines the sampling detail at the stated scan setting, not guaranteed object-detection accuracy. Controller interface - 3.3 V TTL UART, 1 Mbps; use the corresponding electrical interface and driver profile. Compact mechanical integration - 55.6 × 55.6 × 41.3 mm with 115 g typical mass supports enclosure and mounting planning. Distance-dependent accuracy - The current S3 datasheet separates near-range accuracy from longer-range accuracy. These figures are tested at 25 °C on targets with 10-90% reflectivity, rather than being a uniform ±30 mm specification. Official development tools - SLAMTEC provides C++ and ROS-family integration resources. Use the relevant model and transport configuration, then validate scan output before connecting navigation logic. Laser classification - Class 1 under the manufacturer's specified operating conditions. The lidar is a perception component, not a substitute for a certified machine-safety system.

These are range sensors; the host controller supplies SLAM, path planning and robot-level decision making. Application Service and Commercial Robots Integrate the scanner into a delivery, reception or inspection base when the detection range, environmental rating and mechanical envelope match the site. Test narrow corridors, moving people and low-reflectivity surfaces using the assembled robot. Mobile Robot Mapping Use S3 scan data to build occupancy maps and match successive scans against stable walls or structures. Its 0.05-40 m at 70% reflectivity specification helps define the scale of the mapping workspace; a host-side SLAM algorithm and a correctly calibrated sensor frame are still required. Obstacle Awareness and Local Planning Feed range returns into a local cost map to identify objects intersecting the scan plane. Set the mounting height around the obstacles that matter to the platform and combine other sensors for overhanging objects, low obstacles and drop-offs. Robotics Education and ROS Development Teach laser scans, coordinate transforms and localization with the corresponding SLAMTEC driver. Configure 3.3 V TTL UART, 1 Mbps, inspect scan timing, and verify the base-to-sensor transform before testing autonomous motion. Environmental Surveying Prototypes Collect repeated 2D profiles for layout studies and mapping experiments. Building a three-dimensional reconstruction from a moving scanner requires an independent motion estimate and appropriate registration; the scanner alone does not output a complete 3D map. Embedded Perception Integration Check the optical-window clearance, cable routing, supply ripple and startup current before enclosure design. Validate scan continuity with motors and other high-current electronics running, rather than judging performance from an unloaded bench setup. Reference Documents Manuals and Specifications S3 Datasheet S3 User Manual Software and Development Support Downloads RPLIDAR C++ SDK RPLIDAR ROS 2 Driver Packing List SKU Item Quantity Slamtec-S3 Slamtec S3 RPLIDAR S3 LiDAR Sensor 1 FAQ What is the rated measuring range?0.05-40 m at 70% reflectivity; 0.05-15 m at 10%; 0.05-5 m at 2%. Maximum distance depends on target reflectivity, ambient conditions and the selected operating mode.What is the difference between sample rate and scan rate?Sample rate is the number of individual measurements: 32,000 samples/s. Scan rate is how often the rotating scanner updates a full sweep: 10 Hz typical; adjustable 10-20 Hz.Which communication interface does this model use?3.3 V TTL UART, 1 Mbps. Match the host connection and software profile to this exact model, not a similar-looking version.What power supply is required?4.9-5.2 V DC; 5 V typical. Allow for startup current and check voltage at the sensor while it is running.Does this sensor perform SLAM by itself?No. This product supplies laser scan measurements. A host processor running suitable mapping and localization software turns those measurements into maps and robot pose estimates.Can it detect obstacles at every height?No. The laser scans a plane. Mounting height and pitch determine which objects intersect that plane; additional sensing is needed for obstacles or drop-offs outside it.Is the S3 accuracy the same at every distance?0-8 m: ±25 mm; at and beyond 8 m: ±50 mm. The manufacturer tests accuracy at 25 °C on 10-90% reflectivity targets; resolution and accuracy are separate specifications.Which software can I use?Use the official C++ SDK or ROS-family driver in Reference Documents. Select the correct transport, speed and model configuration, inspect live scans, and configure coordinate transforms before using a navigation stack.What is included?Slamtec S3 RPLIDAR S3 LiDAR Sensor: 1 unit. The Packing List records the physical contents of this listing.What should I verify before deployment?Test representative targets, glass, dark surfaces, moving objects and lighting changes. Confirm temperature limits, optical-window clearance, power stability and scan continuity; use independent safeguards wherever people or machinery could be at risk. Show more
