Its official specification combines a full 360° horizontal field of view with 30° vertical coverage for continuous environmental point-cloud acquisition. The sensor provides a 0.2 m to 150 m measurement range, including 90 m at 10% NIST reflectivity, and a typical ±2 cm ranging-accuracy reference. It supports configurable 10 Hz or 20 Hz scanning, single and dual returns, UDP output over Ethernet, and time synchronization for integration into mobile and fixed sensing platforms. RS-Helios-16P delivers calibrated reflectivity measurements, 3D coordinates, and timestamps in its data stream. The current RoboSense development repositories identify this model as RSHELIOS_16P and support it through the official driver and ROS or ROS 2 SDK workflow. Features 16-beam 3D sensing - Sixteen laser channels capture structured multi-layer point clouds for robotics perception, mapping, localization, and obstacle-awareness development. 360° horizontal and 30° vertical coverage - The vertical field spans +15° to -15°, supporting broad surrounding-scene perception. Long-range measurement - The official manual specifies 0.2 m to 150 m measurement range and 90 m at 10% NIST reflectivity. Precision reference - Typical ranging accuracy is specified as ±2 cm using a 50% NIST diffuse reflector under the documented test conditions. Configurable scan density - Horizontal angular resolution is 0.2° or 0.4°, vertical angular resolution is 2°, and frame rate is 10 Hz or 20 Hz. Single and dual-return output - The manual lists 288,000 pts/s in single-return mode and 576,000 pts/s in dual-return mode, with strongest, first, last, and dual return options. Ethernet point-cloud stream - The sensor specifies 100M-Base-T1 Ethernet and UDP packets containing 3D coordinates, calibrated reflectivity, and timestamps. Synchronization options - The official manual lists $GPRMC with 1PPS, PTP, and gPTP for time-synchronization workflows. Industrial operating envelope - The LiDAR body is specified for -30°C to +60°C operation with IP67 protection. Wide supply input - The sensor accepts 9 V to 32 V input and lists 11 W typical power consumption. RoboSense software workflow - Official resources support RSView visualization, PCAP recording and replay, the cross-platform rs_driver kernel, and ROS or ROS 2 point-cloud integration. Point-Cloud Coverage and Configuration The RS-Helios-16P combines 16 channels with 2° vertical angular resolution across 30° of vertical coverage. Select the documented horizontal angular-resolution and rotation-speed settings to balance the required coverage, scan rate, and data volume for the target system. The LiDAR supports strongest, first, last, and dual return modes. Single return provides the documented 288,000 pts/s data rate, while dual return provides 576,000 pts/s. Choose the return mode and host processing budget together, especially when recording PCAP data or operating several sensors on one network. Integration and Data Output The RS-Helios-16P outputs UDP packets over 100M-Base-T1. The official manual defines MSOP as the main data-stream output protocol and DIFOP as the device-information output protocol; the data includes 3D coordinates, calibrated reflectivity, and timestamps. For the documented factory network configuration, the manual lists MSOP port 6699 and DIFOP port 7788. These settings are configurable, so integration software should be aligned with the actual unit configuration rather than assuming factory defaults after deployment.

Robotics mapping and SLAM - Feed calibrated XYZ, reflectivity, and timestamp data into mapping, localization, and sensor-fusion pipelines. Intelligent vehicles and research platforms - Evaluate 16-beam sensing for surrounding-scene perception, road-edge context, and object-awareness algorithms in controlled testing workflows. Industrial automation - Use configurable scan profiles and Ethernet data output for spatial awareness, vehicle guidance, and workcell-monitoring research. Outdoor surveying and spatial capture - Record PCAP data for offline point-cloud review and coordinate-based analysis when the project requires repeatable datasets. ROS and ROS 2 development - Configure the RoboSense SDK with RSHELIOS_16P, then validate the host network, point type, frame settings, and ROS distribution before integration. Multi-sensor timing experiments - Evaluate the documented GPS, PTP, or gPTP synchronization option with compatible external timing hardware and the system-level clock design.
